I/O Biocompatibles Contact Zip T-Shirt - Men's
The 100% merino wool I/O Biomechanics Men's Contact Zip T-Shirt keeps you cool, dry, and smelling like a rose no matter how long you sit out beneath those radio telescopes listening for communications of the third kind. This extremely versatile, long-sleeve merino base layer takes over as your favorite layering piece for anything from a warm alpine day hike to a January morning ride through the great white deep. I/O's Enigma knit keeps things light so you can wear the Contact Zip T-Shirt under a shell or mid-layer on chilly days, or alone when the sun is actually working. I/O's merino wool not only regulates temperature unlike any other textile, I/O uses P-9 wool—a vertically-integrated supply chain that ensures quality performance and equality in the marketplace. The Contact Zip T-Shirt features friction-reducing raglan sleeves and side panels, a form-fitting ribbed knit, and I/O's signature contrast stitching.
Bottom Line: Don the I/O Biomechanics Contact Zip T-Shirt and say goodbye to all your old reeking base layers.
