I have 2 Grenade backpacks, with snowboard straps on the front. Brand new never used. My brother used to ride for them and was friends with Kass when the company was started so they are some of the original ones from Grenade. I never ended up using them though.
One is green camo, the other is gray camo. Priced at $45 OBO. Located in South Jersey, can ship, buyer responsible for shipping.
