- Brand: Under Armour - Color: Blue - Size: YXL - Sleeve Length: Long Sleeve - Features: Highly stretchy This was a beautiful gift. My family wore it a few times over swimsuits as a rash guard. Stored at home by a non-professional, measurements are approximate. For those who understand that this is a used item purchased on Mercari. Please refrain from purchasing if you are sensitive to such things. I will fold it up small to send it.
