I bought these for my 16 and 18 yr old son. I ordered a small and a medium and they fit perfectly. On our holiday they wore them every day in the sea body boarding and they still look brand new. My only negative is that they smell a bit funky when warm.
I use the wetsuit to train in my local swimming pool/gym as i have a problem spine
and the suit keeps me warm.
great feel to the suit not restricting at all
