How to Keep Your Snowboarding Jacket and Pants Waterproof Season After Season

Hey there, fellow powder hound. If you’re like me, your snow gear isn’t just equipment—it’s a trusted companion for every storm chase, every tree run, and every cozy lodge moment. That waterproof shell is your first line of defense against the elements, keeping you dry and focused on the ride. But after a few seasons of face shots and chairlift rides, that legendary waterproofing can start to whisper for a little TLC. The good news? With some simple, consistent care, you can absolutely preserve that “day-one” dryness for years. Let’s break down the how and why.

Understanding Your Waterproof Shield

First, a quick primer on what you’re maintaining. High-performance snow gear uses a durable waterproof/breathable membrane combined with a Durable Water Repellent (DWR) finish on the outer fabric.

• The Membrane: This is the permanent, microscopic barrier inside the jacket or pants that blocks water from entering while allowing sweat vapor to escape. This doesn’t wear out with proper care.
• The DWR: This is the magic coating on the outside of the fabric. It causes water to “bead up” and roll off. This is the part that degrades with use, dirt, oil, and time. When the DWR fails, the fabric soaks through (wets out), which doesn’t mean you’ll get wet inside, but it does reduce breathability and leaves you feeling clammy and weighed down.

Maintenance, therefore, is a two-part mission: cleaning the membrane and replenishing the DWR.

The Golden Rule: Clean Gear is High-Performing Gear

This is the most crucial step. Dirt, body oils, sunscreen, and lodge french fry grease clog the pores of the waterproof membrane and coat the DWR.

1. Prep: Close all zippers and Velcro tabs. Use a technical gear cleaner or a very mild, non-detergent soap. Never use regular detergent, fabric softener, or bleach. These contain additives and surfactants that permanently clog the membrane and strip DWR.
2. Wash: Use a front-loading washing machine (the agitator in a top-loader can be harsh). Run a gentle, warm-water cycle. An extra rinse cycle is a great idea to ensure all soap residue is removed.
3. Dry: Heat is essential. Tumble dry on a low or medium heat setting for about 50-60 minutes. The heat helps reactivate the existing DWR and re-distribute the durable water repellency across the fabric. Never use high heat or iron. Never use dryer sheets. Always air dry first if instructions call for it, but for most technical snow gear, the dryer is your friend.

Replenishing the DWR (The Re-Proofing Step)

Even with proper washing and drying, DWR will eventually need a boost. You’ll know it’s time when water stops beading and instead soaks into the fabric face, creating dark, wet spots.

1. Choose Your Proofer: Use a wash-in or spray-on DWR treatment designed for technical waterproof/breathable fabrics.
2. Application:
   • Wash-In: Great for an all-over refresh. Add it to the wash cycle (following the product’s instructions) instead of detergent, then dry as usual.
   • Spray-On: Ideal for targeting high-wear areas like shoulders, sleeves, and seat patches. Apply to clean, dry gear in a well-ventilated area. Spray evenly until the fabric is lightly saturated, then tumble dry to activate.
3. The Dryer is Key (Again): After applying any DWR treatment, the heat from a tumble dry is non-negotiable for curing and bonding the finish to the fibers.

Storage & Spot Care for Longevity

• Never Store Dirty or Damp: Always clean your gear at the end of the season before storing it. Mildew is a membrane killer.
• Store Properly: Hang your jacket and pants in a cool, dry closet. Avoid compressing them in a stuff sack for long periods, as this can stress the laminate layers and DWR coating.
• Spot Clean: For small stains, use a damp cloth with a tiny bit of technical cleaner. Rinse with a clean, damp cloth and let it air dry, then toss in the dryer on low for 10-15 minutes to re-activate the DWR in that spot.

What to Avoid: The Quick Killers

• Dry Cleaning: The chemicals used can permanently damage the membrane.
• Laundry Detergents & Softeners: As mentioned, these are the arch-nemesis of waterproofing.
• Excessive Abrasion: Be mindful of backpack straps, ski edges, and rough surfaces. While quality gear is built to be enduring, minimizing unnecessary friction extends life.
• Ignoring Minor Repairs: A small seam tape lift or puncture can become a big leak. Use appropriate repair tape or send it in for service before the problem grows.

Built for the Long Run

We believe great gear is built not just to perform on day one, but to be your reliable, enduring partner for countless seasons of discovery. The materials and construction are chosen with longevity in mind, but even the best gear thrives with a little love.

By integrating these simple care steps into your seasonal routine, you’re not just maintaining fabric—you’re preserving memories and ensuring you’re ready for whatever the mountain throws at you next time. Now get out there, breathe deep, and find your next line.
