There are few things as disappointing as gutting out a workout and then, drenched and dehydrated, finally reaching for your water bottle only to suck down a stream of lukewarm water. Or accidentally taking a swig of beer that's been sitting out too long at a summer barbecue. Or taking a sip of coffee that's gone ice cold (not in a good way) less than an hour after you brewed it. None of those things happen when you carry your liquids in a Hydro Flask.

We're big fans of these vacuum-sealed bottles, and were excited to hear that Hydro Flask is offering 25% off sitewide until December 3 with the code HYDRO-25. Hydro Flask products range from 12-ounce water bottles to a 64-ounce beer growler and lots of other options in between, including coffee mugs, food flasks, and wine bottles.

What exactly sets these vessels apart? First of all, they're crafted from nearly indestructible stainless steel and BPA-free plastic that can withstand all sorts of abuse. But it's Hydro Flask’s proprietary TempShield insulation that works the magic. The company promises its vessels will keep your drinks cold for up to 24 hours, even in scorching temps, and our (admittedly unscientific) tests prove they actually do. Case in point: One of our editors left a HydroFlask bottle of cold brew coffee in a hot car in the middle of the summer. Hours later, the liquid was still cold, and the ice cubes were even still intact.

6 Innovations for Your Next Outdoor Adventure:

Hydro Flask products make perfect holiday gifts—that's why they wound up on our lists of the best gifts for outdoorsmen, gifts for beer lovers, and whiskey gifts. You won't find such a wide variety of discounted Hydro Flask products again this season, so shop before December 3 to take advantage of the sale. And if you don't know anyone who enjoys a cold beer (unlikely), check out the rest of our gift guides and Black Friday coverage for inspiration. Maybe a gift guide for guys who are impossible to shop for will do the trick.
