Most are cotton fleece or cotton blends. Some listings use recycled polyester or recycled cotton, and a few include a small spandex content (about 4%).
Inseam lengths vary by listing and include examples such as 10.5", 20", 22.5", 24.5", and 27".
Common options shown in listings include front drawstrings, full elastic waistbands, and fold-over waistbands.
Most listings specify machine wash and tumble dry. Some give more detail, for example machine wash cold and tumble dry on low.
Listings commonly use terms like 'Year Round' (a lighter, all-season construction) and 'Midweight' fleece, so you’ll see both lighter/year-round options and midweight options.
You’ll find relaxed/regular fits, more fitted options, and wide-leg or loose-fit styles across different listings.
Some listings explicitly include spandex (for example 4% in one listing). Many also note 'stretch' or use full elastic waistbands to provide flexibility.
