Price looks good and it appears to have compartments inside to carry other essentials you may need. However, it doesn't look like it can be used as a shooting mat. If all you need is a nice way to carry your rig in a back pack form and have storage for other essentials within the bag I'd say go for it.
I've been looking at these drag bags for several months now and they range from the price levels of this one to $500.00. Quite a spread in prices. If you need a shooting mat several outfits make them for around the same price range as this drag bag your looking at and up. Combine this drag bag with a seperate shooting mat and you'd be set to go in an economical way.
