Nike 3 pack web belt includes one buckle and three straps, one-size, 38mm width. The original package stated it fitted up to 42 waist. We found this not to be the case which is why we are selling them. I would say up to 40 waist, 38 waist would probably be the more desirable “up to” size! All are new, never worn. Out of the original package due to trying one on. The belt itself measures 48 1/2 inches in length. Feel free to ask any questions.
