Control the heat with the Boulder 125 1/4 Zip top. Made from premium Nuyarn merino fabric technology, the 125GSM Australian merino wool is surprisingly warm without adding weight, making it a great option for a long sleeved base layer. The Nuyarn has incredible stretch and recovery, and because it is machine washable and 5x faster drying, it is reliably durable. The YKK Zipper is a simple way to cool down without removing layers if the trail gets a bit hot, and the no-chafe flatlock seams make movement frictionless and smooth. The easy fit cut of the fabric gives full coverage and it is available in sizes XS - XXL.
