Adam T. ★★★★★ Oct 22, 2026

I've worn this on three freezing morning hikes now and the 100% merino wool keeps me warm without any of that scratchy feeling. The long sleeves are long enough to stay tucked under my jacket, and it's become my go-to layer every time I head out.

This thing breathes way better than my old synthetic base layers. Wore it for a chilly morning run and stayed dry and comfortable the whole time.

Ryan ★★★★★ Oct 20, 2026

After a full day of hiking I barely noticed I was wearing it, the merino wool doesn't itch at all like I'd worried. The long sleeves fit perfectly under my flannel without bunching up.
