AQUAFORCE STORM CP WA Approved Model Size 140 Used about 10 times Water-repellent effect is not as good as new, but it's still present. It has been water-repellent treated once with Splash. There are no tears or stretching around the shoulders and back. It can still be used. This is what I was told when I received it. This item has only been tried on, and I have never used Arena, so I don't know the details. Please purchase this item if you have product knowledge and understand that it is used. The condition is listed as "no noticeable stains," but If you are concerned about minor details, please refrain from purchasing.
