Odyssey's Air Supply tubes are specifically sized to fit modern BMX tires, and they are manufactured with a stronger emphasis on quality versus simply chasing the lowest possible price. On average, the Air Supply BMX tube retains air significantly longer than others currently available on the market. This is down to both the rubber that is used, and because of strict quality control during manufacturing. It is normal to assume that a “tube is a tube,” but a higher-quality tube will always last longer than a cheap tube during comparable everyday use.

Not all liner shorts are created equally, and with a patent-pending design, our Mountain Liner Shorts with SWAT intend on keeping it that way.

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 also creating a dual benefit of being highly effective at moisture wicking and evaporation. - Patent-pending & integrated SWAT pockets house all of your trail essentials, putting everything you need right where you want it. - 3D Chamois is pre-molded to match the shape of the body for exceptional comfort. - 8.5" inseam (size Medium). - Fabric Content: 88% Polyester, 12% Elastane
