From my 11 year old surfer girl to my husband who is 6'7" we all have "the" gloves. The XS size fits my daughter and son and we wear M and L and XL. I took the time to write this because we had shopped in stores and could not find gloves that would last more than a 1/2 a season and that felt like our skin NOT gloves. We are in the water all the time and our hands get cold. We wear gloves and these have lasted season after season and do the job. You really may consider a wetsuit wash to kill the bacteria from you gloves boots and wetsuit. They sell it here at Pleasure Sports by body glove and other brands like rip curl, oneill and mirazyme. It is a must have to have your gear last. We love our gloves and your site. Thanks
