O'Neill Men's Premium Skins UPF 50+ Short Sleeve Sun Shirt

The sea blue, green, and white colors are O'Neill 4115B Tees that are 91% nylon and 9% elastane. I don't know about the other colors and logos. If you need a size larger than offered here, I've discovered iSnorkel sells the identical style in various colors as a 4073B right here on Amazon; but, they are a fair bit more expensive. I found the 4115B comfortable in my regular medium t-shirt size. It differs from a basic skins O'Neill 3402 which is 89% polyester and 11% elastane and will hug you tighter. Rinse these tees after use and they keep their stretch for a long time. I've bought many a rash tee and in my view, O'Neill makes the best!

This rash guard is great. I ordered one of these rash guards with a different print before this one, and returned it. It didn't have the little tie strap to tie into your board shorts so it doesn't ride up when surfing. Also, I am a true XL, and even though rash guards are supposed to be snug, it made me feel like a sausage. Replaced it with this one, and I couldn't be happier. The material is great. Nice and thin, and stretches well. It fits perfect, not too small, not too big which is strange because it is the same size and company as the previous one. It also has the tie down loop which is legit.

I originally bought this for myself thinking it would be like a t-shirt I could wear over my swimsuit. It is a fantastic shirt but a little more form fitting than I prefer, so I let my brother try it out. He absolutely loves it. He has always felt slightly uncomfortable without his shirt on in public, so this shirt allowed him to completely relax and enjoy the water. The material is super soft and comfortable and he raved about it so much, my husband requested his own shirt! Definitely a great purchase!

This is a tight fitting shirt, but it's not tight fitting like a compression shirt would be. The material is very light weight and feels comfortable while you are wearing it. It didn't stick to my skin as much as I thought it would when I was swimming with it, however it does tend to lift up on you while you are swimming with it. If you have board shorts on this won't be a problem due to the connector at the bottom of the shirt.

It's high quality, but a little tight. I took two kitchen chairs back-to-back and put the shirt over the seat backs for a couple days to stretch it out. I like the loose-fit better. My high-school daughter was more impressed that I had an "O'Neill" shirt. I had no idea it was such an "in" brand.

We spend a lot of time every summer in the ocean. These rash guards are the best way to avoid sun, scrapes from rocks and coral, etc. I ordered this one to replace an old one. I liked it so much I went back and ordered another one in a different color.

Bought the XXL for my husband and it is snug even though he alters between XL and XXL. He has 2 other O'Neil rash tshirts that fit fine, but for some reason this one doesn't.

I purchased this shift mostly because of how badly I got sunburned last time on the water. This shirt has an SPF rating on it and it really helped. Plus when in the water, I couldn't tell I was wearing a shirt. For my use, it is a great buy!
