The Sea To Summit Frontier UL Collapsible Bowl combines a clever design with durable food-grade materials to help us enjoy functional dinnerware in the backcountry. This bowl is made from glass-reinforced nylon and silicone rubber to ensure it withstands constant jostling in our backpack and won't shatter at the campsite, while the collapsible design allows it to fold down to less then two centimeters for space-conscious storage on the trail.
