Made for high-intensity activities, the Icebreaker 200 Zoneknit Long-Sleeve Crew is equipped with ZoneKnit body mapping technology to regulate your temperature and promote breathability when you’re working up a sweat. The drop tail hem gives you extra coverage when you’re movin’ and groovin’ while the thumb loops keep everything in place. There’s just something about a good shirt with thumb loops, ya know? It’s best suited for mild to cool conditions, with a low profile fit that’s ideal for comfortable layering.
