Emily B. ★★★★★ Oct 22, 2026

The interior fleece is so cozy I wore it as a mid-layer on a cold hike and never felt chilly. The nylon outer blocks wind nicely without feeling stiff or noisy.

Riley ★★★★★ Oct 20, 2026

The inside fleece is so warm I don’t need a midlayer on chilly morning hikes, and the nylon face sheds light rain without soaking through. Fit is trim but not restrictive for active movement.

I’ve been wearing this softshell for a few weeks now—the stretch woven fabric moves with me during hikes without feeling restrictive, and it’s held up well against light wind. The warmth is just right for chilly mornings.
