Everything you need, right where you want it. Sure, it's a simple idea on paper, but there's a reason why there isn't anything else like our Mountain Vest with SWATâ¢ on the market today. To start, it features three integrated pockets that keep your trail essentials right where you want themâon the body. This way, you can leave the stifling, sweaty backpack at home, without having to leave a thing behind. Keys, phone, pumps (there's a special loop for that), tubesâyou name it, and it'll probably fit in one of these pockets. Now, you're probably thinking, "Won't this be hot?" The simple answer is no, but here's why. We made this vest from an extremely lightweight, highly breathable mesh material called VaporRizeâ¢. In fact, if you even notice it at all, you'll find that its added moisture management properties make it feel more like a base layer than a portage device.
