I just read a great review on this Hydro Flask Vacuum Insulated Stainless Steel Water Bottle, Wide Mouth w/Straw Lid. You can get all the details here http://bridgerguide.com/hydro-flask-vacuum-insulated-stainless-steel-water-bottle-wide-mouth-wstraw-lid/. Please repin this. :)
I would so love to fill up a Hydro Flask growler with fresh cold beer from a brew pub and then crack it open and share it with friends around a backcountry campfire. Cold liquids stay cold for 24 hours, and having seen these things in action, I can say that's no exaggeration.
