The ION L/S Slash_Amp is an exceptionally robust and abrasion-resistant cycling jersey for big-mountain adventurers and freeriders. The jersey is made of polyester, which is extremely durable and breathable. Plus, it has quite the baggy fit, allowing for maximum freedom of movement for all those aerial manoeuvres! There is also an integrated pocket for a lift pass, so the jersey is perfect for the bike park. Lastly, ION has used antimicrobial material to inhibit the growth of odour-producing bacteria, making the ION Tee Slash_Amp quite comfortable.
