Why Backpackers Need Rain Shells
Backpacking inherently involves venturing into unpredictable environments, and Mother Nature rarely adheres to a pre-set schedule. One of the most common and potentially detrimental elements backpackers face is rain. A quality rain shell isn’t just an optional piece of gear; it’s a fundamental necessity for comfort, safety, and overall enjoyment of the backcountry. Without adequate rain protection, even a light shower can quickly turn into a miserable experience, leading to chilling temperatures and potential hypothermia.
The primary function of a rain shell is to keep you dry from external moisture, whether it’s precipitation or wind-driven spray. This might seem obvious, but the implications are far-reaching. Staying dry is crucial for regulating your body temperature. When your clothing gets wet, it loses its insulating properties, allowing heat to escape from your body much faster. In cool or cold conditions, this can lead to hypothermia, a dangerous and potentially life-threatening condition. A reliable rain shell acts as a barrier, keeping your core body temperature stable and your spirits high.
Beyond direct rain protection, a good rain shell also offers windproofing. Wind can significantly increase the rate at which your body loses heat, a phenomenon known as wind chill. Even on a dry day, a strong wind can make temperatures feel much colder. Many rain shells are designed with wind-resistant fabrics that block out the wind, adding an extra layer of warmth and comfort, especially during exposed ridge walks or at higher altitudes. This dual functionality makes them an indispensable piece of equipment for any season.
Ultimately, investing in the best backpacking rain shells is an investment in your ability to comfortably and safely pursue your adventures. It allows you to stay out longer, push through challenging weather, and truly experience the wilderness without being constantly hampered by the elements. The right rain shell is a versatile tool that contributes significantly to your well-being and allows you to embrace whatever the trail throws your way.
Key Features to Look for in a Backpacking Rain Shell
When selecting a backpacking rain shell, several key features will significantly impact its performance and your comfort in wet conditions. Foremost among these is the waterproof-breathable fabric. Look for technologies like Gore-Tex, eVent, or proprietary membranes that not only keep precipitation out but also allow perspiration vapor to escape, preventing you from becoming clammy and overheated from the inside.
Beyond the fabric itself, consider the construction and design elements. Seam taping is crucial for true waterproofing; ensure all seams are sealed to prevent water ingress. Adjustable hoods are essential for a secure fit, often featuring a brim to keep rain off your face and a cinch cord to minimize wind intrusion. Pit zips or underarm vents are also invaluable for regulating temperature during high-exertion activities, allowing you to release heat without fully exposing yourself to the elements.
Finally, pay attention to the weight and packability of the shell. For backpacking, every ounce counts, so a lighter shell that compresses down easily into your pack is highly desirable. Look for features like a dedicated stuff sack or a pocket that doubles as a stuff sack. Durability is also a factor; while lighter is often better, a fabric that can withstand some abrasion from your backpack straps or rough terrain will last longer and provide more reliable protection over time.
Materials and Technologies Explained
The heart of any good rain shell lies in its material and the underlying waterproof-breathable technologies. The most well-known is Gore-Tex, which utilizes a microporous membrane that is both waterproof and breathable. Different variations of Gore-Tex, such as Gore-Tex Paclite or Gore-Tex Pro, offer varying levels of durability, breathability, and packability, catering to different backpacking needs.
Other manufacturers have developed their own proprietary technologies. For example, brands like Marmot utilize MemBrain, while The North Face employs Futurelight, and Patagonia has its H2No Performance Standard. These technologies often involve a coating or laminate applied to a fabric, creating a barrier against water while still allowing moisture vapor to pass through. The effectiveness and feel of these materials can vary, making it worthwhile to research specific brand technologies.
Beyond the primary waterproof-breathable layer, the face fabric also plays a role. A DWR (Durable Water Repellent) coating is applied to the outer surface to cause water to bead up and roll off, preventing the fabric from “wetting out” and maintaining its breathability. Over time, this coating can wear off, but it can often be replenished with specialized wash-in treatments.
Proper Care and Maintenance for Longevity
To ensure your backpacking rain shell provides reliable protection for years to come, proper care and maintenance are essential. The most critical aspect is cleaning. Rain shells, especially those with DWR coatings, can accumulate dirt, oils, and residues from sweat and sunscreen. These contaminants can hinder the fabric’s ability to breathe and cause the DWR to break down prematurely.
When it’s time to wash your rain shell, use a specialized technical wash or a mild, non-detergent soap. Avoid fabric softeners, bleach, and harsh detergents, as these can damage the waterproof membrane and the DWR. Most technical washes can be machine washed on a gentle cycle with cool water. It’s often recommended to wash your shell inside out to protect the outer fabric.
After washing, the DWR coating often needs to be reactivated, which is typically done through heat. You can tumble dry your rain shell on a low heat setting for about 20 minutes, or iron it on a low, no-steam setting with a towel placed between the iron and the shell. If the DWR has completely worn off, you can reapply a DWR treatment following the product’s instructions, which often involves washing the garment and then spraying or washing in the treatment.
Understanding Waterproof vs. Water-Resistant
It’s crucial to differentiate between “waterproof” and “water-resistant” when choosing a rain shell for backpacking. A water-resistant garment will shed light moisture and brief showers, but it will eventually soak through in prolonged or heavy rain. These often have a DWR coating but may not have a fully waterproof membrane or sealed seams.
A truly waterproof rain shell, on the other hand, is designed to withstand sustained exposure to heavy rain. This is achieved through the use of specialized waterproof-breathable membranes (like Gore-Tex, eVent, etc.) coupled with fully taped seams. These features create an impermeable barrier against water, ensuring you stay dry even in challenging weather conditions.
For backpacking, especially in areas prone to unpredictable weather or where extended periods of rain are possible, a fully waterproof rain shell is non-negotiable. While water-resistant options might suffice for very casual day hikes in mild conditions, they will quickly prove inadequate for the demands of multi-day trips, potentially leading to hypothermia and a miserable experience. Always prioritize a genuinely waterproof and breathable option for serious backcountry endeavors.
The Ultimate Buyer’s Guide: Finding the Best Backpacking Rain Shells
When you’re venturing into the wilderness, the weather can be your greatest ally or your fiercest adversary. For any serious backpacker, a reliable rain shell is an indispensable piece of gear, offering a critical barrier against the elements. But with a dizzying array of options on the market, how do you navigate the choices to find the absolute best backpacking rain shells for your needs? This guide will break down the essential factors to consider, ensuring you invest in a piece of equipment that will keep you dry, comfortable, and safe on your adventures.
Waterproofness and Breathability: The Essential Duo
The primary function of any rain shell is to keep water out, but achieving this without trapping sweat is equally important for comfort during strenuous activity. This is where the interplay between waterproofness and breathability becomes paramount. Waterproof fabrics prevent liquid water from penetrating, while breathable fabrics allow water vapor (sweat) to escape.
The level of waterproofness is typically measured by hydrostatic head, often expressed in millimeters (mm). A higher mm rating indicates greater resistance to water penetration. For backpacking, a rating of at least 10,000mm is generally recommended, with 15,000mm to 20,000mm offering superior protection. Equally crucial is breathability, commonly measured in grams per square meter per 24 hours (g/m²/24hr), often referred to as MVTR (Moisture Vapor Transmission Rate). A higher MVTR means more sweat can escape, preventing that clammy feeling that can lead to chilling. Aim for a minimum MVTR of 10,000g/m²/24hr, with higher numbers being preferable for active pursuits.
Material Technologies: Membranes vs. Coatings
The way waterproofness and breathability are achieved in rain shells largely comes down to the underlying material technology. The two primary approaches are waterproof-breathable membranes and waterproof coatings. Membranes, such as Gore-Tex and eVent, are typically microporous or monolithic films laminated to the outer fabric. Microporous membranes have tiny pores that are too small for liquid water to pass through but large enough for water vapor to escape. Monolithic membranes are solid films that allow water vapor to diffuse through the material itself.
Waterproof coatings, often made of polyurethane (PU), are applied to the inside of the fabric. While generally less expensive, PU coatings tend to be less breathable and can degrade over time, especially with repeated washing and exposure to UV rays. For serious backpacking, investing in a shell with a reputable membrane technology will generally offer superior long-term performance in both waterproofness and breathability, especially under demanding conditions.
Weight and Packability: The Backpacker’s Priorities
For those carrying everything on their back, every ounce matters. A lightweight and highly packable rain shell can make a significant difference in overall comfort and carrying capacity. Ultralight shells prioritize minimal weight and small packed volume, often achieved through thinner fabrics and fewer features.
Consider the intended use of your shell. If you’re aiming for fast-and-light endeavors or are particularly weight-conscious, an ultralight option might be ideal. However, ultralight fabrics can sometimes be less durable. For general backpacking, a balance between weight and durability is often the sweet spot. Look for shells that pack down small enough to fit easily into a hip belt pocket or the side pocket of your pack, allowing for quick deployment when the weather turns.
Durability and Construction: Built to Last
A rain shell is an investment, and you want it to withstand the rigors of the trail. Durability is influenced by the denier (D) of the face fabric, which indicates the thickness and strength of the yarn. Higher denier fabrics are generally more resistant to abrasion and tears. Seam taping, the process of applying a waterproof tape to the inside of seams, is also crucial for maintaining waterproof integrity.
Look for shells constructed with robust face fabrics, often 30D or higher, especially in high-wear areas like the shoulders and cuffs. Double-stitched or fully taped seams are essential for ensuring that water doesn’t seep through the stitching. Reinforced cuffs, hem, and hood areas can also add to the longevity of the garment. Consider how the shell is constructed – a 2-layer construction with a separate rain-repellent coating on the inside is a common and effective approach, while 2.5-layer and 3-layer constructions offer increasing levels of durability and performance.
Features and Fit: Tailoring to Your Needs
Beyond basic waterproofness, the features and fit of a rain shell can significantly impact its functionality and comfort on the trail. A well-designed hood that cinches down properly without obstructing peripheral vision is essential for protecting your face from driving rain and wind. Pit zips, or underarm ventilation zippers, are invaluable for releasing excess heat and moisture during strenuous activity.
The overall fit of the shell is also critical. It should be roomy enough to accommodate a few insulating layers underneath, such as a fleece or puffy jacket, without feeling restrictive. Articulated sleeves and a dropped hem can provide better coverage and freedom of movement. Consider whether you prefer a more minimalist design with fewer pockets and adjustments for weight savings, or a more feature-rich shell with multiple pockets, adjustable cuffs, and a wire-brimmed hood for enhanced protection.
Environmental Considerations and Sustainability: Making a Responsible Choice
As backpackers, we have a vested interest in preserving the natural environments we explore. Increasingly, brands are focusing on sustainability in their manufacturing processes and material choices. When selecting a rain shell, consider the environmental impact of its production.
Look for shells made with recycled materials, such as recycled polyester or nylon. Many brands are also moving away from PFC-based DWR (Durable Water Repellent) finishes, which can have environmental consequences, in favor of PFC-free alternatives. Researching a brand’s commitment to sustainability and looking for certifications like Bluesign or Fair Trade can help you make a more informed and environmentally responsible purchase.

How do I determine the right size for my rain shell?
The right size for your rain shell is one that allows you to comfortably wear it over your other layers, such as a fleece or insulated jacket, without feeling constricting. It should offer enough room for movement but not be so loose that it creates excess flapping in the wind or allows water to easily seep in.
It’s advisable to try on the rain shell with the types of mid-layers you typically wear while backpacking. Pay attention to the sleeve length and torso length to ensure adequate coverage. Refer to the manufacturer’s sizing chart, which often provides body measurements corresponding to specific sizes, and consider reading reviews for insights into how the jacket fits compared to other brands.
What is the difference between a 2-layer, 2.5-layer, and 3-layer rain shell?
The primary difference lies in their construction and the materials used for the waterproof and breathable membrane. A 2-layer shell consists of an outer face fabric and a waterproof/breathable membrane. A separate lightweight liner is often attached loosely to the inside to protect the membrane, which can feel a bit clammy against the skin.
A 2.5-layer shell uses the same as a 2-layer but adds a protective semi-coating or print on the inside of the membrane, eliminating the need for a separate liner and reducing weight and bulk. A 3-layer shell integrates the waterproof/breathable membrane between the outer face fabric and an inner fabric lining, creating a more durable and comfortable construction that is also highly breathable. 3-layer shells are generally the most robust and comfortable for strenuous activity but also tend to be heavier and more expensive.
How do I care for my backpacking rain shell to maintain its performance?
Proper care is essential to ensure your rain shell continues to repel water and breathe effectively. Regularly clean your shell according to the manufacturer’s instructions, typically with a mild detergent and cool water. Avoid fabric softeners, bleaches, and harsh detergents, as these can degrade the waterproof coating and clog the breathable pores.
After washing, it’s often recommended to tumble dry on a low heat setting. This heat reactivates the DWR treatment, restoring its water-repellent properties. If the DWR seems to be failing, you can reapply a spray-on or wash-in DWR treatment specifically designed for outdoor gear to revitalize its performance.
What is DWR and why is it important for a rain shell?
DWR stands for Durable Water Repellent. It’s a chemical treatment applied to the outer surface of the rain shell’s fabric that causes water to bead up and roll off rather than soaking into the material. This is crucial because even if the underlying membrane is waterproof, if the outer fabric wets out, it can significantly reduce breathability and make you feel colder due to evaporative cooling.
Over time and with repeated use and washing, the DWR treatment can wear off. You’ll notice water no longer beads up but instead soaks into the fabric. Reapplying DWR is a simple process that can restore the shell’s ability to shed water and maintain its optimal performance and comfort.
Are there eco-friendly options for backpacking rain shells?
Yes, many brands are increasingly offering eco-friendly backpacking rain shells made with recycled materials or bluesign® approved fabrics, which ensure responsible and sustainable production practices. Some shells also utilize PFC-free DWR treatments, which are more environmentally friendly than traditional treatments containing perfluorinated compounds.
When looking for eco-friendly options, check product descriptions for certifications like bluesign®, Global Recycled Standard (GRS), or OEKO-TEX®. Supporting brands that prioritize sustainability in their manufacturing processes and material sourcing contributes to reducing the environmental impact of outdoor gear.
