Whether you enjoy hiking, sports, or simply keeping things light when you travel, Mad Man’s Collapsible Water Bottle is a great accessory to have on hand. It’s light, has an easy-to-drink straw built-in to the cap, and a handle for even easier carrying. But the true genius of Mad Man’s Collapsible Water Bottle is its ability to roll up small, so you can toss it in a bag or fanny pack and just go. Dimensions: 10.5 x 2.5 x 2.5
