The Nathan VaporAir is an excellent alternative to wearing two chest-mounted water bottles. It's our Top Pick of all bladder hydration systems. Our testers appreciated the features that make this pack a joy to wear, including a magnetic hose clamp, a Hydrapak water bladder, and a bungee for lashing on a wind breaker jacket. Several convenient pockets make storage and organization a breeze so you can keep your gels from your gadgets. Top it off with lightweight comfort for many miles and you've got a pack that you might find hard to take off after your run. It's a well-designed pack that clearly deserved an award.
This model wasn't the only bladder hydration system that caught our eye. The Patagonia Fore Runner Vest 10L is ideal if you need to carry tons of stuff, but its large size is also heavier.
Nathan makes a women's version of this hydration vest. Called the VaporAiress 2L, it has all the accessible features of the men's model with a fit designed to anatomically fit a woman's body better. With less material, the VaporAiress also weights less at 13.2 oz. Women's packs tend to fit women better, and we're stoked Nathan created a version of this great pack with lady runners in mind.
