When temperatures begin to fall but breathability and dry times are still concerns, the Men's Fuse Long John is your go-to base layer.
Featuring a comfortable, jacquard waistband and a fully articulated fit designed to leverage the structure and stretch of our Aerowool fabric, the Fuse Long John epitomizes versatility in the field.
Lightweight 200 Aerowool construction combines the finest, 17.5 micron merino wool available with 37.5-activated nylon fibers to create a super-charged fabric with incredible performance benefits. What you get is enhanced odor resistance, exponentially improved dry times, increased durability and moisture wicking, and a fabric that can cool you down when you're heating up and warm you up when it's cooling down.
