When I first put it on, thought it may be too big as it was so easy to get into. I think that’s because I was comparing to my 2XU full tri suit. Took a chance and swam at beach and it felt perfect and gave me buoyancy I needed. Love the zip pocket to carry goggles and swim cap riding to beach. Before purchasing I made an enquiry with 2xU about whether Pro-Swim run suit was suitable for riding bike as entering Adventurethon where bike leg before swim. impressed that the staff at 2XU made the effort to ask around for me. Response said not suitable, but wanted to let you know that, apart from being bloody hot to wear in tropical Australia, it’s comfortable on bike seat. Love this product!!
