High quality, durable backpack that fits more than you'd think! For reference, my 24oz Hydroflask fits easily. I was worried about receiving a counterfeit bag, but I bought mine from Movatik and received an authentic bag. It is made in Vietnam so it has the ribbon lined inside seams and small flag attached to the inside. I've seen more than my share of sites comparing authentic bags to counterfeit ones, and I say with confidence mine is the real deal. Received in less than 2 days.
