40Y R&D Long Gore-Tex 3L C-Knit Shell Jacket Man

Peak Performance Men's 40th R&D Long GORE-TEX® 3L C-KNIT™ Shell Jacket

First introduced in 1993, the iconic R&D Long returns for Peak Performance's 40th Anniversary as the benchmark for high-alpine modular outerwear. Built as a versatile 2-in-1 shell-and-liner system, this special edition merges four decades of heritage design with modern material innovations to adapt seamlessly to changing mountain conditions.

3-Layer GORE-TEX C-KNIT™ Shell & Polartec® Alpha™ Direct Liner Engineered with an exclusive 4-way stretch GORE-TEX 3L C-KNIT™ fabric, the outer shell delivers total waterproof, windproof protection with exceptional breathability and a soft, quiet handfeel. Inside, a snap-in detachable liner utilizes lightweight Polartec® Alpha™ Direct insulation (42 gsm 20D ripstop) for active thermal regulation without bulk. Wear the shell and liner together for deep-winter cold, or separate them for spring touring. Cut in a relaxed, seat-length silhouette with a dropped hem, articulated sleeves, and an adjustable waist, hem, and cuffs, it offers total mobility. Advanced features include a 3-way Cohaesive™ helmet-compatible hood, underarm pit zips, a insulated Solarcore® phone pocket to prevent battery drain, an integrated RECCO® rescue reflector, and an anniversary design package.
