Never miss a moment out there with the world’s first built-in micro hydration solution! The 686 Hydrastash Reserve Men's Jacket is a 2-Layer infiDRY® 20K fabric with fully taped seam sealing and 60 grams of insulation built to take on the cold and comes complete with the patented Hydrastash® Powder Skirt. A 4-Way stretch connection band and suspension straps support a 25 oz bladder with an easy rolltop opening for filling and PVC Free and BPA Free micro-Tubing with a Microbite™ valve. Your own body heat keeps this from freezing up for a never-miss-a-chance-to-sip system built into an impressively technical jacket. It’s the forward thinking, no boundaries, styling that makes 686 so impressive. Naturally you’ve got a helmet compatible hood, thumbhole glove links, the pass pocket, and a good half dozen other impressive features you have to read through to appreciate, but suffice it to say you’ve never seen anything more efficient when it comes to packing hydration on the mountain. Ditch the pack which can unbalance you and is cumbersome on the lift for this perfectly designed system and you’ll never look back.
