What Our Gearhead(R) Experts Are Saying:"When temps drop but I still want to hit the trail, this is the tight I grab. It's warm, wicks fast, and the zip pocket actually keeps stuff dry. The bottom zips and reflective hits make it perfect for early starts or late finishes."For frosty trail runs and winter tempo days, the Primal Pant keeps us warm without weighing us down. These thermal tights are purpose-built for movement in cold conditions, with a slim-fitting profile and soft brushed lining that traps heat while letting moisture escape. Flatlock seams reduce chafing during high mileage days, and the waistband features inner mesh for breathable comfort and security. Side stash pockets keep essentials close, while the sweat-proof zip pocket ensures your key or phone stays dry no matter the effort. Bottom hem zippers and reflective accents add function for those pre-dawn starts and dusk finishes.
