Stay cool and dry all summer with the sphere short sleeve Crewe, our best hot weather tee ever. Combining 65% Merino with 20% plant-based Tencel and 15% nylon, we created Cool-Lite, Icebreaker lightest, most breathable fabric. Cooler and faster drying than pure Merino, Cool-Lite still retains Icebreaker signature odor resistance and soft feel. We use a heathered version, with casual set in sleeves and understated tonal logo to create sphere, the summer shirt that's equally at home on a long hot climb as it is on a really slow, deserted beach.
