GU Pajamas Lounge Wear Dark Brown Worn a few times, there are no noticeable stains, but there is a feeling of use such as fluffing and pilling. The surface is not made of a material that is prone to pilling, so it still looks like it can be worn. (The back side has noticeable pilling.) The cuffs have elastic, which was helpful when doing housework. The pants have pockets.
