EVA foam, even the high-density foam we use in our grips, is naturally porous to some degree. Depending on where and how you ski, moisture can work its way into the surface of the foam and contribute to snow and ice buildup.
Where we developed and tested our grips in New England, this was rarely an issue. Deep powder days are less frequent, humidity is generally lower during the coldest part of winter, and consistently cold temperatures help keep the grips relatively dry.
In other mountain climates, conditions can be very different. Deep snow, higher moisture levels, and changing temperatures can cause snow and ice to stick to untreated foam surprisingly quickly. While it doesn't affect the function of the grip, the buildup can become an unnecessary annoyance during a day in the backcountry.
To help prevent this, we've started treating our grips with a wax-based waterproofing treatment, similar to the treatments commonly used on leather ski and work gloves.
All new grips now come pretreated.
Like any wax treatment, it will gradually wear away with use. How often you need to reapply it will depend on how frequently you ski and the conditions you encounter. Fortunately, refreshing the treatment is simple.
How to Reapply the Waterproofing Treatment
- Apply the wax
Wearing gloves, work Sno-Seal or a similar wax-based waterproofing treatment liberally into the surface of the grips. Make sure the foam is evenly coated. - Gently warm the grips
Heat helps the wax penetrate the surface of the EVA foam. We recommend using a hair dryer on high, held at a safe distance, while continuously moving it around the grip.
A heat gun on its lowest setting can also be used, but it should be kept well away from the foam and constantly moving.
If using an oven, use only a low temperature of approximately 150–200°F (65–95°C) and heat the grips for approximately 2–4 minutes, monitoring them continuously.
IMPORTANT: EVA foam can soften, deform, or melt if overheated. Never leave the grips unattended while heating them, and use the minimum amount of heat necessary to warm the wax. The color of the grips will naturally darken with wax treatments.
- Work the wax into the foam
While the wax is still warm, use a gloved hand or clean cloth to massage it back into the grip. Wipe away any excess wax from the surface. - Allow the grips to cool
Let the grips return completely to room temperature before using them. Once cool, the surface should feel treated tacky to the touch.
When Should You Reapply?
There isn't a fixed schedule. Reapply the treatment when you notice the grips beginning to absorb more moisture or when snow and ice start sticking to them more readily.
A few minutes of maintenance can restore the water-resistant finish and help keep your grips clear of unnecessary snow and ice buildup throughout the season.
