XS sweatpants are offered in thermal, fleece, and jersey fabrics.
Common materials include polyester/spandex blends (for example, 90% polyester/10% spandex and 85% polyester/15% spandex) and cotton/polyester blends (for example, 80% cotton/20% polyester). Some listings list only “Polyester, Spandex.”
Most XS sweatpants are tapered-leg with a relaxed fit. Several joggers note a relaxed drop-crotch silhouette, and a few thermal bottoms are described as straight or athletic fit.
Most XS sweatpants use a pull-on closure with an elastic waistband, and many include an adjustable drawstring for a customized fit.
Inseam lengths shown include 26, 27.25, and 28 inches. Garment lengths are described as short, ankle, or full depending on the option.
