It is great for hot weather. Very breathable but not see through. Wish there were more colors!

Favorite T-Shirt
We were hiking out in Zion & Bryce with temps daily over 100 degrees and this was my go-to t-shirt. Super cute cut and lightweight design made this t-shirt my favorite everyday t-shirt for either hiking or dressing up for dinner!

Pretty solid sunshirt
Nice fabric, short and boxy fit as described. I’m usually a small, 5’5” and 130, and small worked for me. If you’re at all busty consider sizing up.

Love this shirt!
Love this shirt, would wear it for every workout if I could! Such a pretty lavender color, flattering slightly cropped fit (sits at my hip), fast drying. For reference I’m 5’5” 115 lbs and got a size XS.
