SE Pro Pant - Myth. SE Pro balances performance and durability for a kit that stays strong race after race. Four-way stretch materials meet articulated construction and durable panels, delivering flexibility and toughness where it matters most. Ergonomically designed for a precise on-bike fit, the SE Pro Pant combines four-way stretch panels with durable materials in key areas. Features: Race Fit. TLD DuraTech fabric combined with durable ripstop paneling creates moderate stretch performance while enhancing durability and overall function. TLD "stealth" belt and secure ratchet system with YKK Vislon "Invisible" zipper system keeps the pant in place while offering more adjustability than more standard waistbands. Dual-panel, full-grain (heat stamped) leather knees with abrasion-resistant internal panels protect from wear and abrasion.
