Today our semi-surly UPS guy brought us a new batch of Hub Bicycle t-shirts. Printed on Alternative Apparel Basic Crew (aa1070). I put one on as soon at they came in (just like our tune-ups, I always take t-shirts for a test ride before sending them out the door) and I can assure you they are very comfy.
One thing to note, in addition to feeling good on your bod, these shirts come from a company with social responsibility policies that'll make you feel good on the inside too.
$22, sizes S-XL, in the shop or by mail (call or email [infoathubbicycledotcom] for shirts-by-mail).
