Water bottles for the arm may not be a novel concept, but the Hydrosleeve is the first water bladder I've seen that caters to the upper body's favorite appendage. For runners and people seeking a way to kiss their massive guns without looking like a narcissist, the Hydrosleeve holds 7 ounces of H20 just a few inches north of the elbow with hands-free access, and without the bulbous protrusion of a plastic container.
The Hydrosleeve's MO is to provide adequate hydration over the course of a run without forcing imbibers to disrupt their cadence or rhythm. Just make sure you keep your eyes on the road while sipping, kids, because I can find no indication that the ergonomically-designed upper arm garter will alert you of potential collisions with SUVs or puggles gallivanting just outside your cone of vision. Available in sizes S, M, and L, the Hydrosleeve adjustable arm band houses its reusable bladder snugly enough to minimize water sloshing, and also includes a supplemental pocket for stashing keys or energy packs.
Running as an Indiegogo crowdfunding campaign through March 24, 2013, the Hydrosleeve still has some early-bird backer units left for the claiming at $30 apiece. Regular price thereafter will be $39 for the buyer's choice of size and color.
Fill a Hydrosleeve with blk. bottled water and...uh...be the guy who drinks black water.
December 2013 Update: Hydrosleeve funding was unsuccessful, and while the company maintains a Website, at present it does not appear that they have proceeded with producing it for the public.
