Material and clip for attaching are top. The side compartment is very tight, Zeckenzange or a single car key goes in. It is disappointing that the bag can not quite pull. When I afterwards sprint my dog, (Hey, Beagles are just so!) I noticed the treats out of the bag. Yesterday we arrived in a heavy rain, the bag was just full. I wonder why the cord is so far down. This lost a lot of space and the bag is quite bulky. Unfortunately I have to still wait a while until I can buy something else to me, from processing it appears unbreakable me.
