40Y Helium Down Jacket Man

Peak Performance Men's 40th Helium Down Jacket

Peak Performance marks its 40th anniversary with this special-edition Helium Down Jacket, the lightest and most packable insulation layer in the line. Designed as an indispensable go-to for high-alpine adventures, freeride skiing, and everyday winter wear, it delivers versatile warmth whether worn as a standalone outer layer or styled underneath a technical shell. This anniversary edition is distinguished by the exclusive 40th Anniversary R&D logo.

Pertex® Diamond Fuse & ExpeDRY Active Down Technology Crafted from ultra-lightweight 38 gsm 20D Pertex® Diamond Fuse ripstop fabric, the outer shell provides exceptional wind resistance, light weather repellency, and superior durability against abrasion. Inside, premium 700-fill power 90/10 duck down is treated with ExpeDRY FUZE® gold-particle technology, which actively accelerates evaporation to keep the down dry and lofty even during high-exertion activity. Peak Performance’s signature "powder 8s" wave-quilting pattern secures the down in place to eliminate cold spots. Cut in a regular fit with extended sleeves for full coverage when reaching or pole-planting, it offers optimal layering room over base layers without adding bulk under shell jackets.
