The Merino Seamless Long Sleeve Base Layer is the holy grail of base layers. As cozy as your favorite pair of wool slippers, yet it transfers moisture like water going through osmosis. It's the perfect recipe for a cool-weather layer courtesy of its Merino and synthetic fabrics. The science behind it is pretty simple. The synthetic yarns pull moisture away from the skin and distributes it across a large surface area where it can be rapidly evaporated. So when you think about it, no moisture buildup means that you won't experience any clammy chills as a result of dramatic temperature swings, and your skin, jersey, and jacket are going to remain dry in order to leave you comfortable. So, when you need to remain consistently warm on chilly days, look no further than this cool weather staple. - Merino and synthetic yarns are blended to create a soft, insulating, and moisture-wicking layer, while also retaining a compressive feel. - Targeted stretch and support areas are built-in, ensuring it moves with your body while you're riding. - Seamless construction provides the best fit and eliminates chafing. - Form Fit closely and precisely conforms to the curves of the body, ensuring an unrivaled level of fit.

You might say that you love your pack, but the massive sweat stain on your back says otherwise. It's time that you carry your trail essentials in the most logical manner possible—carry them with our Mountain Liner Bib Shorts with SWAT. With them, we were able to create a patent-pending design that houses five integrated SWAT pockets on the shorts themselves. The pockets sit flush against the body, and they're shaped and structured to ensure that their contents won't ever come bouncing out. Additionally, the pockets vary in size and location, which means that you'll always have a perfectly shaped pocket for your big and small items, alike. As for the shorts, we designed them to stand on their own, not literally, but in the sense that you'd love wearing them with or without the nifty pockets. To do so, we made them from our beyond lightweight VaporRize mesh fabrics for the utmost in comfort and breathability, while the 9.5-inch inseam (size Medium) plays nicely with shorts when you're layering. For the chamois, you'll get our fan-favorite 3D Chamois insert that's shaped for your body ensuring that it keeps pressure off of soft tissue like nothing else on the market, while also providing enhanced blood flow and plenty of support while in the saddle. We could go even further with medical explanations on why it's so awesome, but what's more important to you is that it's extremely comfortable. - VaporRize mesh fabrics are extremely cool, comfortable, and lightweight, while creating a dual benefit of being highly effective at moisture wicking and evaporation. - Patented & integrated SWAT pockets house all of your trail essentials, putting everything you need right where you want it. - Fold-over leg cuff prevents pinching and discomfort by providing an even, low-volume, and compressive fit over the leg. - 3D Chamois is pre-molded to match the shape of the body for exceptional comfort. - 9.5" inseam (size Medium).

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 Men's Mountain Vest with SWAT on the market today—it rules. To start, it features three integrated pockets that keep your trail essentials right where you want them: on 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), tubes, you 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 and highly breathable mesh material called VaporRize. 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. - Fabric Content: BODY: 88% Polyester, 12% Elastane; POCKET: 77% Nylon, 23% Spandex - Full-length front zipper allows you to control the fit and dump built-up heat on-the-fly. - Slim Fit closely & precisely conforms to the curves of the body, ensuring an unrivaled level of fit and comfort.Three integrated SWAT pockets keep your trail essentials right where you need them, plus there's a dedicated pump loop to keep things safe and organized. - VaporRize mesh fabric construction permits the maximum level of breathability, while still remaining efficient at transferring moisture away from the skin.
