Britt Whitakerwrote a review of Hydro Flask 40oz Wide Mouth Water Bottle on July 17, 2019
Familiarity: I've put it through the wringer
I bought this bottle to replace my 32oz Nalgene and have absolutely zero regrets, I carry it with me everywhere and never have to worry about being dehydrated (because that's something I worry about constantly.) It's also rugged enough to be thrown around the trails and camp. My hydroflask has also kept water cold for 10+ hours in a hot car in summer, which just blew my whole mind. I will say that it's not the lightest water bottle there ever was , as its stainless steel and probably wouldn't carry it with me on longer hikes, rides or backpacking trips.
