Solumbra UPF sun shirt, button up, vented back and armpits, lightweight and loose, perfect for hiking or the beach. Size S, please see chest measurement as this can fit a range of sizes depending on how loose you want it. My clothes are coming from my home which has cats and dogs...they're freshly washed before shipping with organic detergent, but apologies for a hair that might sneak through! Check out my other listings, I'm embracing my new size and purging my entire closet!
