Sea to Summit Ultra-Sil Stuff Sack Roll-top closure Size: 4L Approx. H 30cm x W 20cm x D 10cm Color: Gray * No tag * Not waterproof I purchased this item as used on this site, but I don't think I'll have a chance to use it, so I'm letting it go. Roll-top closure. I think it's a versatile size. As shown in image 5, there are some scratches on the surface. Image 6 is a reference image from the official website. Would anyone looking for this be interested?
