We asked Specialized to make us a custom Purist water bottle featuring our blue and orange stripes. Purist shields the bottle from odor, staining and mold build up, so all you taste is the water. Our custom bottle uses the MoFlo Cap which is easy to open, effortless to use and leak proof when closed. The Purist bottle is made of food-safe LDPE # 4 plastic. It is BPA-free and top-rack dishwasher safe. 22 oz.
