The Supertech line is the absolute top tier of Alpinestars: motocross gear developed with and for factory riders. Every detail comes straight from SX and MXGP competition, from the athletic race fit to the well-thought-out ventilation. The result is an outfit that moves with you like a second skin and gives you maximum freedom of movement when you're riding on the limit — the choice for anyone who wants the very best.
