The men’s Tech Top Long Sleeve Crewe is a midweight version of Icebreaker’s best-selling Oasis base layer. The tops’ heavier fabric weight makes it more than warm enough for mid-winter ski trips, cold weather hiking in excursions, and everyday winter layering. This crew neck is made from soft, breathable, and naturally odour-resistant 100% merino wool. It features offset shoulder seams that reduce friction when carrying a backpack, while forward-set side seams and flatlock stitching prevent chafing during high-intensity pursuits.
