The Sea to Summit X-Cup is the perfect drinking companion, especially designed for those with smaller hands. This compact and flexible silicone cup collapses effortlessly, making it a pocket-sized drinking cup that you can carry with you wherever you go. Its rigid rim ensures a comfortable and secure grip, and it even serves as a calibrated measuring cup, adding a practical touch to your outdoor dining experience.

With a volume of 1 cup (250 ml), the X-Cup is not only convenient but also versatile. Crafted from BPA-free, food-grade flexible silicone, it's a safe choice for your daily hydration needs. The collapsible design makes it incredibly easy to pack, and the calibrated ridges on the sides help you with precise measurements for your beverages.
