Thank you for viewing. Cross-strap design M size (for height 135-160cm, weight 27.5-45kg) posture correction belt. *Please do not mistake this for clothing size M. I purchased this as size M, but it was recommended for up to 160cm in height, so I tried it on, but the size didn't fit, so I'm selling it. It's a like-new item, only worn about 3 times. - Material: 15% Polyester, 70% Neoprene, 15% Nylon - Size: M *Different from clothing size - Design: Cross-strap design - Color: Black - How to use: Hand wash at 30°C
