Jorge Villaltawrote a review of Patagonia Atom 8L Sling Bag on April 26, 2019
Familiarity: I've used it several times
I use this mostly for traveling, this fits all I need for the airplane, passport, boarding passes, a pair of headphones, a small book, keys, etc.
As others mentioned, the feature to pull it in front of you and open it is really nice. The materials are also great quality.
