Up, up, and away! Sometimes a canoe just doesn't cut it. When you can't get there with a paddle, we want you to be able to fly with us. We want you to look and feel your best at all times. The Travel Tube is 60ml and well within TSA limits. Plus, it is made of reusable silicone. We hate waste. Give it a rinse when you get home and fill it up for your next trip.
