O'NEILLMen's Premium Skins UPF 50+ Shorts

I wear them under my board shorts or in my wetsuit, I’ve been wearing them for 15+ years and don’t surf without them.

Must buy for any tropical surf trip imo.

works so well bought a second pair

6'3" 230lbs and my waist is a 37" so some 38" shorts fit okay and some are loose and I can get a 36" on, but they are too tight.Now that you have an idea what size clothes I wear maybe this will help you make a size choice since the sizing charts don't apply to these.A 2XL was too Loose for me. These are suppose to fit like a second skin and not bunch up or move around too easy, just like a performance fit rash guard. The top 6" of the waistband was loose and the hips were loose as well. only the bottom of the legs fit snug enough, but I could tell these would be moving all over and bunching up if I went into the water. I read just about all the reviews to try to gauge which size I should order, but I still guessed wrong.They appear to be very well made, but the lack of a proper size chart can make choosing the correct size a guessing game. This is a product that needs to be tried on to purchase properly because different brands may fit differentlyWhen I ordered these they were $25 with Prime, but when I went to re-order they went up to $40 plus shipping WTH. I am returning these and getting and XL in a different brand name and hopefully I have better fit.

These are great. They provide excellent protection against chaffing and rash under a wet bathing suit. Perfect for a long day at the water park. I am 6’ and 195 and the large is a little tight. They are light weight and easy to wear under a bathing suit.

This ONeil rash guard bottom is amazing. It provides a little warmth as well so it can be used when it's too warm for a wetsuit, but too cold for board shorts alone. It does not restrict at all and moves well with my demanding water sports. I can highly recommend and wish I had these years ago.

I purchased the O’Neil Premium Skins shorts to use under my board shorts and they worked great keeping everything in order and drying fairly quickly. I tried both large (my regular size) and found them too tight. So I opted for x-large. They’re also tight but work better for me.

Pretty comfy. I wear them under board shorts. They stay in place, dry fast and keep by butt crack from showing. A win for everyone, except for those who like to see my butt crack... I do wish they where a bit shorter. They go down to about 3" above my knee but the extra length is probably what keeps them in place. Overall.... Very happy with them.
