Nikwax Skin Proof - 125ml Waterproofing
Keep your skins fast, dry, and ice-free on big days in the mountains.
This high-performance, PFAS-free waterproofer stops moisture from soaking into your skin plush, preventing ice build-up and that dreaded heavy “snowballing.” It boosts glide, reduces drag on the uptrack, and keeps your setup moving efficiently from dawn patrol laps to long traverses.
Why mountain athletes love it:
-
Adds reliable water repellency and stops skin saturation
-
Prevents ice from bonding to fibers—goodbye snow clumping
-
Improves glide and reduces kick for smoother touring
-
Works on all skin materials (nylon, mohair, and blends)
-
Easy sponge-on application—safe to use indoors
-
Water-based, non-flammable, PFAS-free, eco-friendly
Perfect for skimo racers, ski mountaineers, and anyone who wants faster, lighter skins in cold, wet, or variable conditions.
IMPORTANT: Shake bottle before use. Press sponge applicator in center to break seal.
1. Apply to either wet or dry skins while attached to skis.
2. Start at the front of the skin and work liquid into fibers. Ensure the whole skin has been cov-ered.
3. After 2 minutes, remove excess with a damp cloth.
4. Allow to dry naturally before use.
Note: If treating skins before attaching to the ski, ensure adhesive side of skins is not exposed to waterproofing.
