i received my bag in record time, congratulations to the seller. the bag is a very good manufacture it looks solid and is water resistant ... not specify in the announcement, I by cons had some difficulty in placing my Nikon D5100 on the inside, but otherwise it goes in and those with the same grip, for against the possibility of putting in "strap" is downright scam, buy it for its primary function ... backpack reflex water resistant with room on the inside, and against fashion bag back is comfortable
