Breathable base layer for sled days. 20% merino blended with 80% performance polyester keeps warmth when damp, fights odor, and dries fast. 180gsm stretch knit with a contour fit wicks hard without bulk. 1/4 zip dumps heat on the trail, longer drop keeps coverage on reach, and thumbholes lock sleeves under your mid-layer. Flat-lock seams reduce rub under armor or packs.
