The lightweight and breathable mesh material of the SALOMON ACTIVE SKIN 4 makes it the perfect backpack for running and training. - Brand: SALOMON - Model Name: ACTIVE SKIN 4 - Material: Mesh material - Internal Pockets: Yes - Color: Gray Thank you for viewing. I have used it about twice since I bought it, but I'm selling it because it's a little small for me. I think the condition is good, but I'm looking forward to your purchase if you understand that it is a second-hand item.
