The PERFECT bottle for a day outdoors!!! It has larger volume, but still fits perfectly in my hand. For me, kayaking is an all day adventure, and this 34 oz Classic Steel Bamboo bottle is ideal for keeping me hydrated. It's also great to bring with me camping and off roading since I don't have to fill it up as often as I do smaller bottles. My favorite flavors to bring with me for outdoor hydration are Vibe and Boost. I drop two cubes in this bigger bottle and have great tasting water! This awesome bottle gets packed each time I load up my Jeep for a day of outdoor exploring.
