Soft, seamless comfort for working out or chilling out. When you pull the PULSE SEAMLESS LS TEE over your head, you'll realize that this might be the most comfortable shirt you've ever worn. Its blend of merino and polyamide is knitted into one seamless tube, with breathability knitted into the fabric. Chaffing is impossible in this shirt, making it your favorite baselayer, running layer, or ski jersey. And it resists odor naturally, so you can wear it again tomorrow.
