Hi folks, Received this for Christmas and the thoughtful soul that bought it for me can't find the receipt, so it's up for sale as I'm too long in the back for it. Is a size large, which fits a waist to shoulder measurement of 38-46cm. So I'd estimate if you're between 5'9" and 6'1" or 2 you'll be fine, but double check the measurements before buying please. Believe its the latest model, with shoulder straps and integrated kidney belt. Ideal under a one-piece suit. See attached pics. £45 posted via courier. paypal friends payment please.
