Smartwool specifically sources high-grade Merino that bends easily, preventing the scratchy sensation associated with older wool garments. The fabric is smooth enough to be worn comfortably as a base or mid-layer.

This is a major advantage over synthetic polyester garments that tend to retain body odor after heavy sweating. You can wear a Smartwool Merino sweater for multiple days on a hiking trip without it smelling.
