The Sea to Summit X-Cup is the collapsible camping cup that disappears into your pack when you don't need it and springs back to a sturdy, freestanding cup when you do. Made from food-grade flexible silicone, it handles hot coffee at the campfire just as well as cold water on the trail — and collapses to a flat disk that fits in the palm of your hand.
Part of the Sea to Summit X-Series camp kitchen range, the X-Cup pairs perfectly with a collapsible pot for camping — together they make a complete, ultra-packable cooking and drinking kit that takes up almost no space in your pack.
