Rab Men's Merino 120 Long-Sleeve Zip Tee

Providing plenty of warmth while remaining breathable, the Rab Merino 120 long-sleeve zip tee is a go-to midlayer for year-round adventures in the mountains or around town. Made with superfine merino wool and polyester, it’s moisture wicking and dries quickly in the event of a downpour. The fabric has also been treated with 37.5 Technology, which actively responds to body heat by turning liquid into vapor. The deep YKK chest zipper provides ventilation on balmy days and can be zipped all the way up to give you extra insulation around your neck. Finally, the flatlock, low-bulk seams prevent chafing and pack wear, while the close-fitting collar offers a form-fitting feel and prevent drafts from slipping through.

Rab was founded by Scottish mountaineer Rab Carrington in 1980 Sheffield, England. Drawing from his experience expeditioning in the Alps, the Himalayas, the Andes, and elsewhere, Carrington began making down sleeping bags and clothing for the climbing community. Production started in his attic, and as demand grew, moved to a factory in Sheffield. Since then, the company has expanded its offerings to include a full range of climbing and mountaineering apparel—most notably its rain jackets and down parkas—plus sleeping bags, shelters, gaiters, and gloves. Featuring innovative insulation technologies and some of the lightest materials out there, Rab’s products are hardwearing, no-nonsense, and built for adventure.
