So to material and processing Needless nothing more to write. The handling and the size of the bag is really extremely practical with an SLR and a lens or an SLR with a larger lens attachment. There are also two cameras viewfinder when the lenses are not too large. I use them for a Fuji XPro and a Rollei 35TE, plus film, filters and sunglasses. Fits. No huge box dangling around his shoulder. Absolutely perfect and totally inconspicuous. The hook and loop fasteners can I find imho something American, saying something oversized. But work well and keep even large caliber from falling out of the bag from. If at any time my number one choice.
