can i wear it without out a wetsuit?
I wear it all the time with out a wetsuit. During summer in Florida it's to hot with a wetsuit.
yes, actually that's what I do during summer
Yes. Have worn in Bahamas next to skin, also Northeast freshwater. And didn't buy it to wear over wetsuit originally myself. Also fine for distance swimming. I forget the specific SPF specs though.
Yup, I use mine without a wetsuit only. It works the same as a normal rashguard. Note that it doesn't have a loading pad, which isn't the end of the world unless you plan to load more than 5-10 times
