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. 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. Gusseted underams gives you freedom of movement to reel in a record breaking northern pike. Open the neck zipper when you need a little air to cool down. Even if week long winter camping isn't your idea of fun, the longer length lets you tuck it in without sporting tails. The next to skin fit lets you sport a trim profile complete the look with jeans and driving loafers.
