If youve ever worked on your own motorcycle you know this anxiety! That moment when the rider realizes he failed to tighten the axle and things are going bad in a hurry. The Biltwell Oops tanktop is a 3.5 oz. 65/35 polyester/combed cotton in a relaxed fit blank. Hemmed with oversized armholes and 1x1 baby rib set-in collar. Slight taildrop hem with side seams and a lightly screen-printed label.
