Size S. Leg loops are fixed, approximately 48cm. I used it with a waist of 73cm, and I think the usable range is about 69cm to 73cm. I bought it 10 years ago and used it a few times. I stored it in a dark place with good conditions, so I think there are no problems with use. Please refrain from purchasing if you are concerned about safety. If you're interested, please consider purchasing. - Brand: Misty - Color: Black - Type: 1 buckle - Features: Fixed leg loops (indoor use) - Size: S Thank you for viewing.
