The "Runathon" Variation has the pictured Runathon logo on the back, rather than the "Standard" Tree logo that is on the back of all other items. *This is a larger, looser-fitting shirt. Therefore, it may be wise to order 1 size smaller than normal. This is a North Face "Velocitee", and is sold (unprinted) by for-profit businesses for $25 plus tax. We are able to offer it for only a $20 donation to the GIVE shirt movement (plus, as always, a $5 donation to another charity of your choice), due to a special Sponsorship/Partnership we have with The North Face. The $20 donation pays for the shirt, shipping to and from the printer, environmentally-friendly reflective print on front and back, and all other expenses of the GIVE shirt movement!
