Rash guard for overweight man?

[outofofficebrb]

I can't speak to the finer points of fabrics, but I did want to say that many cheaper technical tees also cite a SPF/UPF sunscreen factor and so far I haven't had any trouble getting sunburned through them (mine are old, and I am as pale as Elmer's glue). YMMV, but for a new diver I'd recommend saving money better spent on other diving stuff.

It's probably fine. More than likely the UPF is still there even when stretched when wet, but it may not be a as high as originally quoted. Not a dealbreaker, but just something to keep in mind.
