"I live in Phoenix Arizona and have been looking for the coolest t shirts to replace my aging and ragged collection. After many months and a lot of money I have finally found the coolest t-shirts available. Coolibar…."
"I have bought other shirts and nowhere on the packaging or on the shirt does it say UPF 50 or that it blocks UVA /UVB rays and then when I wear them I get so sweaty. With Coolibar it says it right on the label on the shirt. I work out in the sun every single day and they keep me fresh and protected these shirts are great"

"retuning since the shirt is way too big as a medium."
"Feels as good as it looks"
"rat fabrics and paterns"
"Overall, I really like these shirts. I have purchased six because I really want them to be better than they are, but without fail the shirts will massively stretch out given time. The main issue is the collars which will fully loose shape but the shirt itself also grows much longer. I thought at first this was a problem with how it was being washed. But I have follow the instruction carefully and still the same problem. I have noticed it occurs most with the blue colors and the black holds up longer, Still, not holding out hope the black shirts will last either."
"All good"
"Love these shirts, very comfortable and perfect for lounging by the pool or beach at your favorite resort."
