Ive had several Timbuk2 bags over the years (messenger bags and backpacks) and this is my first bag with their updated material and design for the classic messenger. I had some concerns due to limited negative reviews on Amazon and the manufacturers website. But my experience has been nothing but positive. All of the changes to the design are well thought out improvements including the lip on side opening of the bag that folds in the keep water out, the new lighter weight material, and the changed placement of the straps under the flap for aesthetics and to act as optional compression for the bag. The new material is also still highly waterproof and durable.  The bag came with a nice cushioned shoulder strap that previously I had to replace on older models as they used to be just uncomfortable nylon wraps.

There is also plenty of pockets for organizing both inside and outside of the bag. There is a laptop divider good for a e-device or papers you don't want crushed. And it also still has a simple big compartment inside. The addition of a low profile handle on the outside of the bag so you can carry it like a briefcase is very useful as well.  The new strap adjustment system also works like a charm and is easy and quick to operate.  Check the manufacturers website for a good video tour that highlights all of the features.

Ive taken this bag on an international trip to Iceland. I wore it everyday and even wore it while pushing a stuck tour-bus on top of a mountain in Iceland out of three feet of snow.  I also take it with me to work on my regular commute via bus. It has held up great (still looks brand new) and the small size is perfect to carry everything I need but not so big that is cant comfortably sit on my lap for 45 mins without taking up much space. I have seen two other commuters with the same bag.  Its comfortable to wear for an extended amount of time and easy to run with while wearing.  I carry in the bag a 21 oz water bottle, my lunch, an umbrella, some magazines, a work binder, a toiletry bag, pill bottles, keys, a work badge, pens, hand sanitizer, and earbuds. I would also have space to stuff in more things or a wind jacket. The small messenger is a great size for travelers or commuters.  The small might be viewed more as a medium compared to other brands as the medium Timbuktu bag is too big in my opinion unless you are an absolute packrat or bike messenger.  The medium might be the right size if you want to also carry a pair of shoes or a bike helmet in your bag. The large would be for people who want to carry a full wetsuit, shoes, and bike helmet in your bag.

The bottom line is I love this bag and and Im happy I bought it. Its proven tough, versatile, professional looking, well designed, and ergonomic. I cant identify with any of the criticisms from other negative reviews. My bags build quality is fantastic and the changes they have made to its design have significantly improved my experience compared to using their older style bags.  I would highly recommend this bag.
