After testing the flow, the 5/16th diameter tubing really stands out, delivering a high-volume stream that prevents that annoying thirst-driven struggle mid-trail. Since it is manufactured by HydraPak, the build quality feels incredibly robust and dependable. I particularly love the slide seal design. It opens wide enough to make refilling a breeze and seals tight enough to prevent any messy leaks in your pack.

The dual-sided adjustment and single speed hook make it incredibly easy to secure, while the no-slip breathable webbing keeps heat from building up. You get two included BPA-free UltraFlask 550 bottles, but the real versatility lies in the 4-way stretch mesh and tuck-away straps that easily accommodate a jacket or Z-poles.
