Width: 2.5cm, Length: 30cm. Set of 2. I prefer wider belts as thinner ones can feel constricting. They are not stretchy, so you don't have to worry about them being too tight. Those with slender ankles may be able to use them on their ankles. Please measure before purchasing. There's a difference in the amount of water that gets in when you fall, depending on whether you're wearing them or not. *Ankle straps (35cm long) are also available. No price reduction.
