A reusable water bottle as healthy as the water you put inside it. The KOR ONE Hydration Vessel ($30) is BPA-free (good for your body) and cuts down on the amount of water bottles you throw away each year (good for the planet). The KOR ONE features a pretty stunning industrial design, topped off with a just-right spout and a hinged cap (screw you, screw-on caps) for quick one-hand opening and closing.
Forget the basement boxing ring — if you really want to spend your Friday nights in bloody battles, check out these Throwdown Pro Series MMA Cages ($16,500 and up). Available in three shapes — circle, hexagon, and octagon — the cages feature patented heavy-duty framing, closed-cell polyethylene foam padding, extra-wide corner bumper pads, all-steel stairs, and vinyl skirting. All you need is an announcer, some bleachers, and an opponent.
It used to be that the best soccer cleats featured filthy-soft leather uppers. Not any more. The Cristiano Ronaldo-approved Nike Mercurial Vapor SL Firm Ground Soccer Cleats ($400) are made almost entirely from carbon fiber, from the molded carbon fiber upper to the seven-layer outsole plate made from carbon composite interwoven with TPU and polyurethane. If you're looking for the world's most advanced boot, this is it. [Thanks, Ben]
