The Alpinestars Atom racing suit features a soft and comfortable 2-layer construction that is certified to the SFI 3.2a/5 standard. The attractive and durable twill outer layer is paired with a soft inner lining for comfort and breathability. Driver comfort is improved with stretch panels through the crotch and back, along with pre-curved arms and legs to enhance mobility. Extended, full-float shoulders provide a relaxed fit, while elastic cuffs on the legs and arms keep things in place, and a boot-cut flap keeps things stylish.
