The original artwork on this Tech Lite Tee is a drawing of the Tongariro Alpine Crossing in New Zealand. Simple, natural elements combine to form an abstract version of this beautiful place, captured by artist William Carden Horton. Kind of like the simple, natural beauty of merino wool, and the ethos we share at Icebreaker. And the Tech Lite Short sleeve is another illustration of this ethos. Made from 150gm merino jersey, this simple tee keeps you cool when it's warm, warm when it's cool, and fights odor when you're trekking or traveling for back to back days. For this season, we've used a Nylon core wrapped in merino wool construction to enhance durability and longevity of your tech lite tee.
