Look good, Smell good, and stay good and warm. Whether you're ice fishing for a week or entering a team in the Iditarod, you won't be doing laundry for a while. The Arc'teryx Men's Long-Sleeve Rho LTW Zip-Neck top was designed with you in mind. Rho LTW provides a close-fitting garment that maintains its shape and aids in transferring moisture away from the body. Made from New Zealand Merino wool, this top naturally regulates your temperature and minimizes bacterial growth so the shirt won't stink like a football locker room after a day on the trail. The touch of elastane lets the shirt bounce back, day in and day out, for extended wear.
