    Simplicity is the name of the game. It carries fluid, and it does it well with no gimmicks or bells and whistles. The flask is easy to grip and squeeze, and the hand retention system is snug, breathable, and extremely comfortable. I had no hesitation using it during at the Devil Dog 100k, and it never left my hand. Highly recommend!

    My go-to handheld. The harness is really comfortable for long runs and holds the bottle for you with zero thumb effort/numbness. The bottle itself is easy to squeeze, flows well and doesn’t leak. It has a big enough opening to get drink mix/ice in without too much hassle and if you need to stash it in your shorts for a bit there aren’t any zippers to cause discomfort. I have tried squeezing it to reduce sloshing on the go but it doesn’t conform to my hand after doing that so I just leave the bottle un-squeezed (the sloshing isn’t bad anyhow). If you want a really simple and comfy handheld with no bells or whistles this is my top pick.

  3. Rated 5 out of 5


    By-far the best handheld. My hands are somewhat small, but the bottle conforms well and the strap adjusts to fit perfectly. It doesn’t move while I’m running nor does it cause any discomfort in my hand. Easy to drink out of and really lightweight. Love this handheld!
