Vapur 1-Liter Anti-Bottle

Tested from the Rockies of Colorado to the Wrangells of Alaska, the beaches of Indonesia to the jungles of Sri Lanka, the Vapur 1-Liter Anti-Bottle is a space age, space-saving flexible flask that our team can’t get enough of. The bottle is straightforward and easy-to use: the carabiner-equipped top unscrews for quick refills, and clips onto backpack loops without difficulty. When filled, the bottle is still slender compared to your average 1-liter water bottle and can be compressed and jimmied into awkward angles to fit various water bottle pockets and backpack configurations. The true magic of the Anti-Bottle, of course, reveals itself with every sip. As you drain the bottle, the flexible plastic bladder reduces in volume. By the time you finish, the bottle weighs next to nothing and can be folded flat to slide in your pack or rolled up to be stuffed into your pocket.

Tester Comment: “I love snowboarding with one of these in my pocket. I don’t usually like carrying water or even wearing a camelbak when I’m riding at the resort. Riding with a full Vapur encourages me to chug fast and hydrate, and then once I’m finished, I don’t even notice the bladder’s in my pocket! Backpacking, splitboarding, international travel—you name it and I’ve done it with my Vapur. Of course, I prefer a stainless-steel bottle in hot weather, as these Vapur bottles don’t insulate at all. That said, I recommend getting two 1-liter bottles for bigger trips—that usually does it for me. Also, they make a flask now, too, which is pretty neat when bringing whiskey into the woods.”

Bottom Line: Vapur saves weight and slashes volume—two things that every adventurer can get behind.

Best for: Daily use, travel, backpacking, everything under the sun
