I've used this a few times, but it no longer fits, so I'm selling it. It has one pocket on the outside. It has a hook and netting to prevent drops and escapes. The shoulder straps are adjustable. The shoulder strap padding is wide, about 12cm, and lightly cushioned, so my shoulders never hurt. A 5kg dog used it. Since it's a used item, there may be some hair that I couldn't remove. For those who understand. I will fold it compactly and ship it.
