Atsko – so your ski and outdoor gear stays in top condition season after season
Atsko is an American brand specializing in equipment care that has relied on two classics for decades: Sno-Seal, a beeswax-based waterproofing treatment for leather, and Sport-Wash, a residue-free detergent for technical fabrics. Both products share the same goal—to preserve the functionality of your gear rather than burdening it with fragrances, optical brighteners, or softeners that eventually compromise membranes and waterproofing. For skiers, this means: leather boots that stay waterproof even in wet powder, and hardshell jackets that let water bead off again after washing instead of soaking it up. At ski-shop.ch, you’ll find “ Atsko ” as a handy combo product to keep all your gear in top shape before and during the season.

Beeswax Waterproofing
Leather that stays waterproof even in firn and wet snow
Sno-Seal is a beeswax-based waterproofing paste that penetrates deeply into vegetable-tanned smooth leather and suede, forming a durable, water-repellent film. Unlike many sprays, Sno-Seal doesn’t wash out after just a few uses; it remains effective even after hours of contact with wet firn or puddles in the parking lot. It’s best to apply the paste thinly and evenly to clean, slightly warmed leather using a cloth or brush, let it soak in for a few minutes, and then buff off any excess wax. This treatment pays off noticeably before the first snowfall, especially for fur-lined boots, leather mountaineering boots, or the outer materials of some ski boot liners. A side effect that many appreciate: The leather is simultaneously nourished and kept supple, rather than drying out and becoming cracked over time.
If you’re using Sno-Seal for the first time, the easiest way to start is with the Sport-Wash Sno-Seal 1890ml, which combines waterproofing directly with the right detergent for the rest of your gear. Since one tube usually lasts for several pairs of shoes over multiple seasons, it’s worth the purchase even if you only have one or two pairs of leather shoes in your closet. By the way, the waterproofing appears darkest on light-colored leathers; a quick test on an inconspicuous spot will show you in advance how much the color changes. Combined with regular care, a pair of shoes that’s been properly waterproofed once will often last several winters before needing another treatment. You can find the complete Atsko range, along with additional application instructions, collected on the Atsko brand page at ski-shop.ch.
Residue-free detergent
Technical fabrics require technical care
Regular delicate-wash detergent often contains fragrances, optical brighteners, and fabric softener residues that can become lodged in the pores of membranes like Gore-Tex and noticeably reduce breathability. Sport-Wash deliberately avoids all these additives and cleans hardshell jackets, softshells, down jackets, and merino base layers without damaging the fiber structure or the water-repellent treatment. Because the detergent contains no fragrances, it’s also well-suited for people with sensitive skin or fragrance allergies who often can’t tolerate conventional detergents. In practice, just a small amount is needed per wash cycle, so experience shows that a larger bottle lasts for many washes. After washing with Sport-Wash, water beads off technical fabrics noticeably better than after washing with regular detergent, especially when the water-repellent treatment is additionally refreshed with a separate water-repellent treatment.
Sport-Wash Sno-Seal 1890ml comes with a generous amount of detergent, enough for numerous wash cycles and suitable for the whole family when multiple jackets and pants need to be cared for. For best results, wash technical clothing separately from cotton items to prevent lint or residue from other fabrics from sticking to the membrane. A low spin cycle and avoiding fabric softener round out the proper washing routine and further extend the lifespan of your gear. Especially at the start of the season, when your ski jacket has been stored in the basement since last winter, it’s worth giving it a thorough wash with Sport-Wash before heading back out onto the slopes.

Care Routine for the Entire Season
Ready for action from the first run to the end of the season
Whether it’s a ski tour in powder snow, a winter hike around a frozen mountain lake, or a day on the slopes—your gear is constantly exposed to moisture, cold, and mechanical stress. Atsko Therefore, view care not as a one-time measure, but as a routine that’s best planned before the first snowfall and repeated as needed throughout the season. If you thoroughly treat your leather boots, gloves, and hardshell jacket once in the fall, you’ll avoid many wet feet and clammy hands throughout the winter. Even in the middle of the season, it’s worth checking your gear—for example, if water no longer beads off properly or if the leather around the seams is darkening again because it’s absorbing moisture. That way, your focus stays where it belongs—on the next run or the next climb—rather than on soaked or damp gear.
For a complete care starter kit, the Sport-Wash Sno-Seal 1890ml is usually sufficient, as it covers both the waterproofing for leather parts and the detergent for all technical textiles. If you’re often out in wet snow or rain, it’s best to re-waterproof your boots and gloves before every extended touring season, even if they still look intact on the outside. For families with multiple pieces of gear, it’s worth scheduling a dedicated care session on the weekend before the first snowfall to go through the entire wardrobe at once. Even after particularly muddy or salty outings—such as on groomed slopes in the spring—a thorough cleaning helps prevent residues from settling into the membrane or leather.
