This velvet-feel microfleece top is one of our best sellers all year round for good reason. The classic design features a half-zip fastening – perfect for slipping on when the temperature cools. An easy-care insulating layer in a rainbow's-worth of seasonal colourways. Made from 100% recycled microfleece.

An all-season favorite, the Classic All-Season Merino Base Layer Long Sleeve can be sported as a base layer in the fall or summer when it's time to go backpacking.

This base layer features Core Spun technology—which features Merino wrapped around a nylon core for added durability while still keeping the comfort of ultra-soft, responsibly sourced Merino next to skin.

Smartwool's Raglan sleeves eliminate shoulder seams for perfect comfort under a pack, and smooth merrow stitching wraps from side to front to keep you looking as good as you feel.
