Triathlon Shorts - Mens triathalon apparel by Aero Tech Designs. We have a selection of men tri shorts that feature a thin chamois that dries quickly. Swim, bike, run. Men's triathlon shorts are a comfortable and lightweight. We offer a couple different styles that you can wear while training or on race day. Both shorts are aerodynamically designed so you can perform at your best. Tri shorts are definitely a must whenever you have a race. Tri shorts are a necessity in any swim, bike run event. The pad that is in the shorts is just thick enough that it will keep you comfortable on the bike but will dry very quickly after the swim. This is where bike shorts and triathlon shorts differ. Bicycle short fabric usually isn't designed to stand up to chlorine. A cycling short pad is also thicker which will not dry as quickly as our Triathlon short pads. A main part of the triathlon where racers want to save some time is during the transitions between the swim, bike, run. Since these shorts offer support on the bike, comfort while running, and ready to swim in, you will not have to worry about wasting time changing.
