First off, I accidentally ordered a small. I always wear a medium. So it will not be as tight fitting on someone who wears a size small. But I wanted to try it on and review it as I loved it that much. It is a beautiful aqua blue and I hope that shows up in the video and pictures. It is really soft and is just the right length. Since there are slits in it, you may want to wear tights/shorts that are higher waisted. This shirt is perfect for any outdoor activities or any athletic experiences. You can tell this shirt is a high quality piece. The polyester fabric is made out of recycled bottles and it is UPF 50+. I'm really happy with this purchase. I know it will last me years to come.
Love the shirt - the price is great, fabric feels nice, sun protection and doesn't wrinkle (machine washes/dries great on low)! I just ordered my third shirt now (in white - also have black and grey). I have several long-sleeve sun shirts, but live in Texas so I like a short sleeve sun protection shirt to wear in the summer when it gets crazy hot (that way I only have to put sunscreen on lower arms and face). I love the that it goes down in the back and front with a split on sides. I find this style slimming and gives me a little butt coverage when wearing leggings. I am 5'2" (32D) and weight about 123 lbs and long-waisted. I probably could wear a S, but I typically purchase M in shirts because I don't like them too tight (prefer more of a loose fit). So I ordered the medium and fits nice - loose but not too much.
Very comfortable great for being seen while cycling.
The shirt arrived on time. It's the second PINSPARK shirt I've ordered. It fits wells, true to size although could be a little loser in bust area but still fits well. Easy to launder and usually hang to dry. Good shirt.
Love these shirts! Cool in the summertime!
I need more colors! These dont wrinkle. They fit well and give a nice shape to you. Give me greens, tans, browns, a red, an autum yellow please! I am an autum color palette and I need more warm toned colors. I've bought 5 colors and they are wonderful but not quite the colors that go with my skin tone so you know how much I love them if I'm buying them regardless. They are very comfortable. These would be cute with a v neck too. The light colors aren't very see through either with skin tone undergarments. I wore them while on a boat in direct sun and 85+ degree weather and kept me protected from the sun and wicked moisture to keep me cool.
This dry fit top is nice and airy to wear while working out on a hot summer day. It is light and loose-fitting, but true to size. It falls just below the waist. The back is slightly longer than the front making it perfect to wear with leggings.
Absolutely lovely pink, just like on screen, very lightweight and breathable, but doesnt show my bra, unless I go with a black, but even then it wasnt bad (was too anxious to check the fit). Feels pretty comfortable in the warm sun, that slash rises a little high when I raise my arms all the way up (Im 5 so I have to raise my arms up fully a lot) but still feel ok and like Im not actually showing any midriff/sides. Thought it might be too thick to feel cool but its great, very comfy, fits well all over, shoulders, arms/biceps, rib cage, great length that will work for people taller too (Im used to things a little long but with the variation between front and back it looks good on me too). Used the size chart to order and small fit well, which is my usual size. Well made, looks exactly as it should, easy to get on and off over my head (usually stay away from a crew neck), feels comfortable on my clavicles. This compares to my fancier active shirts too, in terms of function, comfort, and quality.
This MIER Womens UPF 50+ Sun Protection Workout Tops Short Sleeve UV SPF T-Shirt fit as expected. The fabric is soft. I like this shirt.
I got this shirt for my wife since I have had so much luck with Mier running clothes. The fabric is light and dries quickly. She recently wore this shirt for a full marathon and said it was very comfortable and didnt cause any chafing or rubbing. I will continue to purchase Mier clothing.
