How to buy rashguards:


Look for rash guards that are UPF rated. Most of our rash guards qualify for the UPF 50 rating and a few are even rated UPF50+. UPF means Ultraviolet Protection Factor. It’s similar to SPF for sunscreens that we are all familiar with. So a rash guard shirt with UPF of 50 only allows 1/50th of the UV radiation through to the skin. Other than UPF, you should look at color; darker is better but hotter to wear if that is a factor. Weight (thickness) is also a factor. Cheap rash guards you may find on the web are very lightweight. We don’t sell cheap quality here but we start at midweight and have heavier shirts such as O’Neill for additional protection. Also as a rash guard stretches, its UPF goes down, so order one large enough! If you've got any other questions, please be sure to check our (FAQ) page covering Frequently asked Questions.

IrRashional™ for Adults!

Whether you are looking for an MMA shirt, SPF shirt, or just plain sun protection for water sports, do it differently than the rest! Irrashional shirts protect and make a statement while saving your money!

The best value in rash guards today! RashGuard Shirt Company is proud to offer a 6.5oz shirt with S.P.F. protection of 50 at the price of a budget shirt. How did we do it? First off, 6 ounces just won't provide a UPF 50+ rating (except in the darkest colors) so we went with 6.5, keeping material costs down. Also, on that note, we've kept our shirts short – guys, they won't go over your shorts – and perfect for ladies who want to “ride it up a bit” to show off that belly ring. So our overall weight of the entire garment is the same amount as our competitors – but they only offer 1/15th of UV block!

We designed a polo cut neck which is slightly higher than budget shirts. You'll have more sun protection for the same price (and less critters getting in your shirt when you are in the water.) This also helps with wetsuit chaffing.

Best price. Best Value. The rational choice in rash guards.
