PRELIGHT SUNCOOL LS M

No more bulky layers underneath. The fabric breathes surprisingly well even when I'm pushing hard on an uphill climb, and the freedom of movement is much better than my old cotton tee. Wore it for a full day on the trail and didn't feel restricted once.

Took this on a weekend hike and the slim fit really stays put under a pack without bunching up. The fabric moves well and breathes enough to keep from feeling clammy on the uphill sections.

Used this as a baselayer on a chilly morning hike and the slim fit really allows for full range of motion without any bunching. The fabric breathes surprisingly well, kept me comfortable even when I started sweating.
