After an outdoor adventure, nothing beats unwinding by the river. Their Serotonin River Graphic Short Sleeve Tee aims to bring that same sense of calm and comfort, with a relaxed feel and organically grown cotton next to skin. The structured silhouette of this standard fit tee gives it a more put-together look, with all the moisture management, temperature regulation, and odor resistance of Merino wool to help you feel good wherever the next adventure may be.
