This undershirt has been designed with comfort in mind. Wearing it will keep you cooler than going without an undershirt, even on a hot day. Sounds strange doesn't it?
It's made from moisture wicking material that ensures your core temperature stays at an optimal level on long hot rides or quick races at the track.
When it's not quite cool enough for thermals, but you need an extra barrier for the initial cold shock on early morning rides coming in to winter, this will keep you happy on the bike...happy and comfortable.
It also creates an extra added layer in case of a mishap with the ground, helping save your skin from becoming one with the road or track.
Plus all the cool people wear them.
