Kids riding base layer underwear.
PAUL in CA
I live in SoCal and use this vest for all my Desert riding and hot days at the track. It really does help you push harder, longer. It can be quite a shock to the bod when you first put it on but it's well worth it. I wear it under all my gear (chest protector and jersey). Air movement really helps some; if you're going slow it's not as effective and high humidity has the same effect.Read All Reviews
