I purchased this about two years ago at Ishii Sports Tozan Honten. I used it once that year, but I haven't done any climbing since then, and I won't be using this for mountain trips in the future, so I'm putting it up for sale. The condition is as shown in the photos. There is a hole in the mesh near the center. Due to the nature of the product, there is a hole, but it's minor, so I think it will still be useful. Please sew the hole to prevent it from expanding further. There is no brand name listed, but I bought it at a mountaineering specialty store, so I think it's functionally sound. There are also instructions for attachment, so if you apply them, I think it can be used with various backpacks. Due to the condition and nature of the product, please understand that it is non-returnable and non-refundable. Shipping will be done with the item taken out of its bag and folded compactly.
