I purchased this bag to take on a 1 week vacation. I liked the slim design and the sling for easy access to my camera while still wearing the bag. Unfortunately I had to return it because the fabric started to pull away from the zipper after using it for only a week. I ended up returning it to Amazon ( a little annoyed that they charged me a restocking fee on a defective item) and ordering a different brand that is a little bigger and has more features. Hope it lasts longer than this one.
Output:
negative
