The slim fit is spot on—snug without feeling restrictive, so it layers cleanly under a shell. I wore it on a breezy ridge walk and stayed comfortable the whole time, no bunching or ride-up. It’s become my go-to for days when the forecast can’t make up its mind.

I wear this as a midlayer on chilly morning hikes and the zipper glides smoothly, plus the slim fit doesn't bunch under my shell. Perfect weight for staying warm without overheating when I'm moving.

The slim fit is exactly what I wanted—it layers under my shell without any bunching. Wore it on a chilly morning hike and stayed comfortable the whole time; just wish the zipper pull were a bit easier to grab with gloves on.
