base layer pants

Many listings use polyester–spandex blends; examples include 90% polyester/10% spandex, 87% polyester/13% spandex, and 95% polyester/5% spandex.

Listings include thermal fabrics and velour, and several descriptions call out fleece-lined construction for added warmth.

Available fits include straight‑leg (athletic), slim‑leg, and skinny‑leg styles; listed rises include Regular, Mid Rise, and High Rise.

Many items use moisture‑wicking fibers or fabrics and quick‑drying construction to pull sweat away from the skin and help keep you dry.

Most are pull‑on styles with an elastic waistband that keeps the bottoms in place without excessive tightness.

Many list stretch or 4‑way stretch fabrics, which provide room for easy movement and help support activity and layering.

Listings reference Midweight and Lightweight fabric weights for base layer pants.
