Large duffel bag, the packed properly has a lot of storage space. Ideal for traveling, where you do not constantly have to take anything out of the backpack. The seams are well made and keep packed full of some. Good to wear the backpack straps. Closure is easy to handle and to have also maintains close or remain on.
The only drawback are some semi-loose threads and something sharp buckles to adjust the length of the strap.
