Enjoy your favorite backcountry beverages in the Sea-to-Summit X-Cup Collapsible Cup. The X-Cup is constructed of high quality food-grade silicone, which won't impart plastic taste into your drinks. A rigid nylon ring gives the Cup some stability and prevents scalded fingertips when you partake in hot drinks. The X-Cup nests with the X-Bowl and X-Plate to fit compactly in your backpack. The X-Cup is dishwasher- and microwave-safe so you can clean it up when you get out of the backcountry.
