MIER Women's UPF 50+ Sun Shirts Long Sleeve Workout UV Protection Dry Fit Athletic Running Gym Hiking Tops Lightweight

I'm usually a small (S), but depending on the brand, sometimes extra-small (XS) works better (happens especially with all the clothes I buy at Costco). I purchased the white upf 50 rash guard in an XS, and it was the right call.The fabric feels a bit thin, and I have yet to test it out for its sun protection and cooling features on long, sunny hikes. But, it sure does fit well and looks nicer than another rash guard I have. Washes well and isn't sheer. In spite of sizing down, it isn't snug fitting on me - it hugs my chest, but is forgiving around the belly. The bottom hem is curved with side slits. I plan to wear the rash guard with high waisted upf 50 leggings, so no part of my skin will be exposed to the sun anyway. The sleeve is neither excessively long, nor snug or loose - it's just right on me. The top is a little shorter on the front than on the back (kind of like a high-low top) but covers my tummy and butt just fine. I must mention that I actually like that the top isn't very long in the front. I'm 5'3", and around 118 lb, in case that helps folks decide upon the size.I would have preferred that the fabric were slightly thicker, and the color were more of an ivory white (this is more of a bluish tinted white that I'm not overly fond of, but really, nothing to complain about), but overall, for the price, this is a good buy.

Love the light soft material, fits perfectly, it’s exactly what I wanted

Perfect fit!

El material es muy delgado. En duda que pueda bloquear rayos UV. En duda la duración del producto.

These are a nice fit, true to size. The color is really nice and the fabric feels soft on the skin. Overall very good quality.
