Love those Atoms
As a connoisseur of the Patagonia Atom (have many of them, almost all available colors), I have appreciated this slight variation: the lightweight travel sling is made of extremely light fabric. This difference allows the bag to be rolled up and stuffed into its own pocket. The colors I purchased (purple and bright red, one of each) are both very vibrant and cheery. I find this particular style of bag/backpack to be very useful when carrying small quantities of things, like the essentials of wallet, car keys, cell phone, and Netflix DVDs to be dropped off at the post office. I would buy this item again; and I likely will do so in the future, when new models/colors come out from Patagonia.

Perfect small travel bag
I use this to carry my belongings on my bike rides to work each day. Perfect for sunglasses, long sleeve shirt and the myriad of items we tend to haul around each day. Has a separate small pocket for coin purse, keys etc.

pretty but not efficient
i really like the color options on this lightweight sling. however, the fabric is so lightweight that it got caught in the zipper. also there is only an open pocket on the shoulder area where there is a zippered pocket on the more substantial atom. i had to return it because i had to use both hands consistently to open it simply to avoid the zipper from jamming with the fabric.
