The men’s Tech Lite Short Sleeve Crewe is icebreaker’s go-anywhere adventure Tee. Its super-comfortable feel and fit are thanks to its construction – 87% merino wool and 13% nylon. Durable Corespun fibers with a nylon core wrapped in wool add strength while placing soft merino next to your skin. Merino wool is naturally odor-resistant, quick-drying, and comfortable, making this the perfect top for summer outside.
