VaporKrar 12L 2.0 Insulated Hydration Vest

Once you've signed up for that ultra, it's time to step up your gear game with the VaporKrar 12L 2.0 Insulated Hydration Vest from Nathan. With an ultra-distance race your hydration needs to be on point, along with your snack game and all other items that help you perform on race day—like water-resistant layers and a dialed playlist. Thankfully, there are plenty of pockets on this leveled-up hydration vest to organize everything you need on mile 3 or mile 73 to help you feel prepared at the starting line.

With a next-to-skin feel, the VaporKrar vest hugs your body like a t-shirt, and the side-body compression straps dial in the fit to help reduce pack movement on the trail. The pack will inevitably move with your body, but the updated hourglass shape of the insulated hydration pack will keep water from sloshing around as you maneuver scree fields or overgrown trail on your way to the finish line.
