This is a brand new active t-shirt from Coolibar, which creates clothes that protect you from the sun. This has UPF50 protection, long sleeves, it is lightweight and breathable, perfect for hiking or outdoors activities. It has a little pocket on the side and holes in the sleeves to cover your hands and pull the thumb through. These are expensive functional clothes.
I bought a few items from this shop online and never used this one, let me know if interested :)
