A bottle is only as good as its cap, which is why we brought the best parts of our Rambler® Chug Cap to the brand new Yonder™ Cap. Spin the top off when you need a drink from the controlled spout, twist off the bottom when you're ready to refill or wash it. No more sloshing water all over your face and because it's 100% leakproof, maps and socks stay dry in your bag.
