This looked really comfy and breathable, and also not very synthetic material. But it only last the first time I put it on. I washed it on a 'Delicate' wash program with cold water and let it dry on the rack (so absolutely no tumble dry). And then now it doesn't stay at waist! Rolls over down my hips and waist constantly! So absolutely not working as an active wear and going to be my pyjama probably. Very disappointed!
