Sleeves trump bare arms when it comes to aerodynamics, but most skin suits are sewn with only the aero bike position in mind. Danish company Fusion Sports developed this tri-specific speed suit to function for both the bike and the run. The back is made from fatigue-reducing compression fabric, while the front utilizes a lightweight, breathable Lycra that disperses sweat quickly to keep you cool and dry. The whole thing is SPF 50 for added sun protection and it comes in five color options. [$266; fusionsportsuk.co.uk]
