Great little travel bag.
I bought this for travel, but have been "trying it out" every day for the last couple of weeks. I'd been searching for a bag in this style where it can expand if needed and this fits that. When it's folded, I can fit my wallet, both readers and sunglasses, a small pouch with misc items and my keys. The pocket under the flap when folded can also fit a pair of glasses, keys and lip balm. When unfolded, I can fit more including my water 24oz water bottle. I do wish it was just a tad larger as it seems small. And maybe a more comfortable strap which seems scratchy. Other than that, I'm really liking this bag. I have not utilized the locking/unlocking yet.
