Most rain shells announce the mountain before the forecast turns. The Peak Performance Treeline HIPE 2.5L Shell Jacket takes a quieter route, placing credible wet-weather construction inside a relaxed, city-compatible silhouette.

The men’s jacket uses a 50-denier ripstop face with Peak Performance’s 2.5-layer HIPE membrane, rated to 10,000mm for waterproofing and 10,000 g/m²/24h for breathability. Fully sealed seams handle the main entry points, while concealed zippered hand pockets keep the front visually clean. The full-length closure is a reversed YKK coil zipper—not an AquaGuard zipper—and the hood, cuffs, and hem are adjustable.

At roughly 13.7 ounces, the Treeline is light enough to carry but more substantial than an ultralight emergency shell. That middle position suits trail-to-town gear: the ripstop has enough texture to signal utility, yet the relaxed, boxy proportion leaves room for a sweatshirt or light insulation without resembling expedition equipment. Understated chest and sleeve prints keep branding secondary, and a women’s cut applies the same 2.5-layer brief.

The Treeline HIPE 2.5L Shell Jacket is priced at $250 on Peak Performance’s U.S. site. Availability varies by color and size: the live product selector currently shows purchasable combinations alongside sold-out options. A matching women’s version is also listed at $250.
