Keep your bum nice and dry with The Ass Gasket seat warmer. If you’re a skier or snowboarder, you’ll love that this gives you a totally waterproof barrier between you and the wet chairlift. Made of YULEX plant-based tree rubber, this accessory keeps you totally dry. So, whether you’re sitting in snow to buckle in or riding on a chairlift, you won’t be cold and wet when you’re done. In fact, it can even keep your bum up to 25º warmer after a 5-minute chairlift ride. This means you’ll be so much more comfortable as you sail down the mountain. Because most waterproof outerwear is only water resistant, water can still permeate it. That’s why you want this 100% waterproof seat warmer, which uses closed-cell insulation to be totally impermeable and maintain warmth. Finally, it’s super easy to put on and take off without removing your other clothing.
