This is easily one of the nicest sling bags I’ve owned! Sorry but I am not 100% sure of the model name but if my memory is right, it's the Alpha Bravo Saratoga. I’m letting it go because I’m no longer working and just don’t need a top tier bag of this caliber anymore. Really nice colors in grey and brown. I think they were called anthracite & hickory. Materials, zippers, straps, and just the overall feel are all excellent. It also has a hidden zipped pocket behind one of the vertical canvas straps in front. Few people know about this and it took be a while to find it, too. The ID tag has never been used (see pic). It has "RSA" monogrammed on the leather patch, but other than that, it looks and feels practically brand new. It's about 14.5" high by 9" wide and about 5" thick. I'd say it is approx 8 or 9 liters capacity. Check out the photos taken today for the full details. I pack securely and shipped fast. Thanks for looking. You'll be very pleased here.
