Ella ★★★★★ Oct 22, 2026

The 3-layer Gore-Tex is noticeably lighter than my old shell, and it still shrugs off a full downpour during a bike commute without any wet-out. Folds down small enough to live in my pack, which is exactly what I wanted for an all-mountain layer.

Daniel ★★★★★ Oct 21, 2026

Packed this for a week of rainy trail hiking and barely felt it in my pack—the 3-layer GORE-TEX kept me bone dry through a downpour while staying surprisingly breathable on the climbs. It’s the lightest shell I’ve owned, which makes it easy to throw on without thinking twice.

Ella ★★★★★ Oct 20, 2026

Finally a shell that's genuinely light enough to forget in my pack but still handles everything the mountain throws at it. The three-layer Gore-Tex breathes well enough that I don't soak through from the inside on a climb.
