This shirt is for the the little ladies twisting the throttle or wrenching in the garage. This design was hand drawn one summer night and picked out of our sketchbook to become a part of the TDSC lineup. The Throttle Down Speed Co. Flying Piston T-shirt is all about speed and style. This shirt is perfect for summer nights in the garage or at the track. The 100% ringspun cotton purple shirt features a grey design with pink accents. This is a unique offering from TDSC, as it features a set-in 1x1 baby rib collar and a longer length.
