Reddit mentions: The best diving rash guard shirts

That depends how much skin you want to show, and what style you're going for.

For tops, there are lots of options. The sports bra type look, which shows your belly but not much chest. There's a cropped rash guard which covers even more chest but still shows the belly. Then you've got the bikini that shows the most of everything, or the tankini, which covers the belly but is low cut at the top like a bikini. There's an even longer version of tankinis now called a swim dress that I think is cute. I love this long sleeved, belly-showing rash guard too.

Now, if you don't want to show a lot of skin there's a short sleeved rash guard, or long sleeved rash guard that all cover the belly and chest completely. They have all kinds of colors of these things.

For the bottoms, there are always plain old board shorts for everyone. There are shorter ones too. There are tons of colors and lengths for those.

You could wear a bikini bottom by itself or under your board shorts. There are a zillion colors and styles of those. There are swim boxer briefs that you can wear alone or under shorts too. If you want the bikini look but are concerned about the shape of your genitals, there are plenty of bottoms in the men's clothing section that look fantastic and would be easy to match to a bikini or tankini top.

Sanabul's are pretty basic and cheap, but might not be as thick as you want. Their fight shorts are the best I've tried too. I got this one: https://www.amazon.com/Sanabul-Essentials-Sleeve-Compression-X-LARGE/dp/B01M6Z44H9/ref=sr_1_1?ie=UTF8&qid=1485981028&sr=8-1&keywords=sanabul+rash+guard

i wore the purple shirt here to a no-gi class and at least one person assumed that meant i was a purple belt. they figured out pretty quickly that wasn't the case. I didn't even realize the colors were all the belt colors. i just like purple. whoooooops.

Appreciate it, doridori!

Found one on Amazon I really like: Sanabul Funk Strike Long Sleeve Compression Training Rash Guard for MMA BJJ Wrestling (Small, Black Swirl)

I will suggest getting a rash guard with SPF. I've really loved having one. Only thing you need to worry about then is your neck, hands, and potentially any space between your bottoms and the bottom of the shirt!

Wear a hat too. I have a camo boonie hat that I wore in CR. I fashioned a strap out from a shoe I found on the beach. It did the job mostly.

One of my cohorts has a long sleeve rash guard with a hood. I used it once, it was ok but I couldn't get used to having a hood on and if it was off it felt like a sea anchor whenever i went under.

I do have a few O'Neal SS and LS 50 spf rash guards, got them cheap online. Used both in CR during the mid day sun, saved my ass. I SUP more than surf, these are nice enough that I can be in them all day then go out for beers/food post paddle and not look like a filthy hippy.

Although I don't like their gis at all, Sanabul rashguards are legit. Less than $20, ranked, and vented armpits

I wear rash guard shorts and a thin wetsuit vest. The wetsuit vest doesn’t move around at all which was the problem I had with normal rash guards. The rash guard shorts stay in place even when my trunks ride up.

Wetsuit vest - I think I bought this from cleanline surf or one of those. Can’t find it.
