There are many reasons to replace several of your favorite tee shirts with the Tech Lite Short Sleeve Crewe when you pack for an adventure. The first is comfort. A customer favorite since Icebreaker's early years, the Tech Lite Short Sleeve Crewe now features our corespun fabric, soft merino wool fibers wrapped around a nylon core, for enhanced durability and longevity. Because it's merino, you can wear it several times between washings, because the one thing you probably don't want to look for when you're sightseeing is a laundromat.
