I recently purchased this UV long sleeve shirt for outdoor activities, and I'm extremely satisfied with my choice. It offers excellent UV protection with a UPF rating of 50+, keeping me safe while at my sons soccer game. The lightweight, breathable fabric kept me cool and comfortable, and its moisture-wicking properties worked well. The fit is was a little flowy. While it is slightly pricier than other options, the quality and performance make it worth the investment. I highly recommend this shirt for anyone seeking a stylish and functional solution for outdoor adventures!

Ideal fabric, great fit.

Color: Light Pink, Size: Medium

Loose fitting back is ideal for hiking, walking and other outdoor activities. The fabric is breathable - great for working out. Even though the back if loose fitting, the front and boatneck fit well.

Prefect coverage and cooling.

I have to have sun protection and I live in the south. This is perfect for my daily walks. Covers what I don’t want to put sun screen on, the loose fit hides tummy area and loose in back. Liked it so much, I just ordered two more. Soft, silky, and Very cooling and lightweight.

Weird spot on it.

Color: Black, Size: Large

I kind of like this top, especially the feel of it. Unfortunately, it has an odd stain on the front. Looks like a heat mark from being pressed? I hope it comes out because I threw the bag away. If it does come out I'll take down this review.
