125 Cool-Lite Long Sleeve T-Shirt

[This review was collected as part of a promotion.] wore the Sphere Tee on a mix of trail runs, day hikes, and a backpacking trip through the Grand Canyon. It handled warm-weather effort really well. Even in black, it felt surprisingly cool and breathable, with good airflow during sustained climbs. It dried fast when sweaty and never got that heavy, clingy feeling. It was comfortable against my skin even when I was pushing hard, which isn't always the case with merino. I didn't expect how often I'd wear it off the trail. The fabric is really soft, and the fit looks good without feeling too tight or restrictive. It's become a go to for hanging at home, working, or running errands. I received this product for free in exchange for my honest review, but already want it in another color!
