Typically buy these from coofandy. This was my first from jmierr. Great purchase. Good material. Great fit. Not super thin material or super thick. Good and comfortable. Would purchase again!

Solid 2pc set
Hubby recently had hip replacement surgery & needed some comfier clothes while he's recuperating.
These are really comfy but they fit well and the subtle stripe just looks a little more "put together" than a standard sweat suit. This isn't his normal style but he's becoming a fan 🙂
Wash and dry well- no special treatment and no wrinkling or shrinkage. Warm but not hot, seem to be well made... not seeing pilling or strings unraveling, etc 👍👍
