Sea to Summit wants to make sure you can eat your oatmeal comfortably on backpacking trips, which is why the Delta Bowl has a Protex hex pattern at the base to keep your food nice and toasty for a long time. Made out of food-grade nylon, this bowl is both lightweight and safe to eat out of. There are measurement increments on the inside to help you cook, and an thumbhole gives you a good grip on the bowl.
