Absolute horrible quality
Color: Black, Size: Medium
Do not purchase this track suit even if its on sale. The fabric material is so cheap, it feels like a tacky uncomfortable plastic bottle that's been stretched out over your body. The stitching feels very off and the thickness is somehow too bulky and looks baggy and at the same time feels too tight. Do yourself a favor and avoid, I'm returning this product.

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 👍👍
