Bought this for a trip to Cozumel, Mexico, where most sunscreen is illegal (it's harmful to the reefs/marine life). I'm a pasty guy who burns easily, but with a couple of these sun shirts, combined with an SPF hat with neck guard, I never had to use sunscreen the whole trip unless I wanted to, despite being out in the sun swimming/scuba diving off of boats the entire time. Went home without getting sunburned once.For when you're out of the water and in the sun, I'd honestly consider this safer than sunscreen, when combined with the right headwear. Not to mention that sunscreen is just not a great experience. You get back to your place and you're all covered in greasy oil and want to shower immediately. With these, you don't have to deal with any of that.The material is comfortable/breathable, you don't feel overly sweaty (at least not any more than you would in a comparable t-shirt or whatever). Definitely get this if you plan to be in the sun and can't, or don't want to, use sunscreen. The protective hat with neck guard is very important as well, so don't forget that.
