User Review and Pictorial – Hydro Flask in Action

Since picking up my ingeniously designed Hydro Flask several weeks ago, I’ve taken it on more outings than I can easily recount. Not only that, I’ve subjected it to all the customary conditions and treatment my outdoor gear usually receives in the Wasatch Mountain Range. The Hydro Flask has been shaken inside my hand or backpack for long distances while running, hiking, and mountain biking, and it hasn’t leaked so much as a drop. The disclaimer here is that I’ve only been using a narrow mouth loop cap, not the sports cap. For further details, I’m regularly using the 24 ounce size – in Everest Blue, if you’re curious.

I have dropped my flask (accidentally, of course), added flavored powders, performed iodine water treatments, jogged with it in hand, camped with it in freezing temperatures (it’s already snowed in the Wasatch), taken it on bike rides, and used it to transport hot chocolate & brandy, as well as using it indoors. It performs as the company states, with virtually no problems in sight. There has been zero staining nor any flavor transfers between any of my variously flavored concoctions. Temperature transference between the environment and the fluids inside has been negligible. Zero metallic, or even plastic-y taste has crossed my lips, since there’s no liner. All that, and the bottle easily rinses clean between uses!

I haven’t yet subjected the flask to the temperature extremes of Wyoming’s sub-zero winters where I often head to ski in the chilly Tetons, but I will, and will report back on the performance when winter finally rolls around. In the meantime, the bottle has performed through several 100+ degree Salt Lake City days in an admirable fashion. Picking up my Hydro Flask after it’s been in my car in bright sunshine with the windows closed, and finding the vessel hot to the touch, I’ve been awed to discover my beverage still pleasantly chilled – and I rarely use ice!

One user tip to point out so far: When the bottle is filled and taken to an altitude several thousand feet above the filling elevation, pressure does build up since the flask’s metal walls don’t expand as do softer components. It is useful to twist the cap off slowly for the first ¾ turn, which cuts down on spray. There’s still a bit of pressure blow off using this technique – even with plain water – but it’s not enough of an issue to detract meaningfully from the Hydro Flask’s substantially larger number of positives. Following are some photos of this vessel in action, and at rest.

Another day drinking by White Pine Lake after another trail run. How can you tell it's a different day? The water is ten feet lower than the previous lakeside shot!

The Wasatch Crest Trail is worth doing again and again, just like drinking out of a Hydro Flask!
