Outstanding Bag
by on
This is an excellent bag and my first Mountiansmith product. I've tried so many over the years and I'm sad to admit it's taken me this long to finally find the one I love.

The material is tough and durable but not so tough that the bag is stiff as a board, it's sleek, handsome and offers lots and lots of organization which is perfect for my slight OCD, lol.

I've had the "tactical" style bags and I wanted to get away from that look and this bag does it without sacrificing durability and functianabiliy. I love the neoprene type material for the laptop sleeve, super soft and protective for your electronics. More than enough room for files books, lunch, a light coat, name it.

I work in the city and commute daily on a train and this bag is easily transitionable from the car to the train to walking a few blocks to the office. I really can't say enough good things about it and I'll be buying another for backup in case its somehow discontinued down the line.

Thank you Mountainsmith for a great product.
