What Our Gearhead(R) Experts Are Saying:"This piece lives at the top of my layering drawer. The Summit Crew is lightweight but handles sweat like a champ, and the vented pits plus thumbholes make it perfect for layering under a shell or wearing solo on high-output climbs."The Summit Crewneck Top is our go-to base layer when temps drop and output ramps up. Designed with versatility and breathability in mind, this lightweight piece thrives in alpine pursuits-from dawn patrol skins to full-day mountain missions. Made with VERSA(TM) fabric, it manages moisture, blocks odor, and delivers buttery-soft stretch that keeps us comfortable when we're on the move. We appreciate the thoughtful features: vented armpits regulate airflow, flatlock seams reduce chafing, and a dropped hem gives extra coverage under packs. Finished with thumbholes and a tapered fit, the Summit Crewneck layers like a pro and performs just as well on its own during high-exertion sessions.
