Review: Love this long rash guard - This is the 2nd one of these I've purchased, I love it. You really need something on nice and tight and even in a 3xl for me, it has plenty of room and lots of length. I don't have to worry about the sun, it hold my big stomach in place, and covers any crack that may try to show through! I've been out all day in this, in and out of the water, and its easy to forget its on as it dries quick and lets the air in.
Review: Sizing is right on and the quality is perfect - I wear an extra large t-shirt and the extra large Mares rash guard fits perfectly. People that have stated in reviews that the sizing is way small don't realize what they are ordering. This is a rashguard not a t-shirt. A rash guard is supposed to fit like a second skin. If it fits loose, you will continue to get rashes. I used to get terrible rashes under my armpits when I wore my wetsuit for any long period of time in the water. I no longer get those rashes since I use this rash guard. The quality is great. The styling and look of the rash guard is spot on. If you're looking to find a t-shirt go somewhere else. If you're looking for a high-quality rash guard that will protect your body from rashes and chafing go no farther. This product delivers 100%. I paid for this product and was given any incentive to write this review. I wrote this review because I felt people needed to know what the product was and also the quality of it.

### ⭐⭐⭐⭐ Nice quality swim shirt but snug fit
*by N***L on February 10, 2016*

My son likes the higher collar to protect his shoulders completely from sunburn. The fabric is nice and has a comfortable fit but definitely runs on the small side. My son normally wears a medium in men's and I got him an extra large. He likes swim shirts with a little looser fit. For my son, the extra large fits like I would expect a normal medium to fit. If you like a real snug fit I recommend just going up one size.
