Most items list machine wash. Drying instructions vary: some recommend tumble drying (often listing tumble dry low), while others advise line drying or explicitly recommend against tumble drying.
Listings highlight reinforced seams, full or comfort elastic waistbands, pull-on pant styles, shoulder snaps or buttons on tops, easy-zip hoodie fronts, and ribbed cuffs to help pieces stay in place.
