Big Zip™ EVO Reservoir

The faster flow rate is no joke, I drained half of it on a steep climb without feeling like I was fighting the bite valve. Took it on a 12-mile hike and there was zero plastic aftertaste, which was my main gripe with my old reservoir.

The wide opening makes filling it at a campsite sink so much easier than my old bladder, and I love that there's zero plasticky aftertaste even on a hot day. Water flows fast enough that I don't have to suck hard to get a drink mid-hike, which honestly sold me on it.

The flow rate really is noticeably quicker than my old bladder—no more sucking hard mid-climb just to get a sip. It’s been on three rocky hikes so far and not a single hint of plastic taste, which honestly surprised me.
