Seedy Three Messenger Bags by Crumpler

Pros: Comfy, Secure, Roomy, Bombproof, Nice Looking, Excellect Customer Service
Cons: None. Really, not one.

I've had my Crumpler bag over three years now and have been very pleased. It serves as my daily pack for a three mile commute and is my daily backpack for school. It is just so comfy and holds so much that I don't even bother using a grocery pannier to shop anymore. This is truly a do it all bag that I'd buy again in a heartbeat.

In terms of roominess, just last Friday I was the hit of the party as I cruised in with a thirty pack slipped inside it!!! Yes, a 30 pack! There's a few nice pockets inside (for wallet, keys, etc.) but it isn't cluttered like is so often the case.

Pros: Light, roomy, seems well-made
Cons: None, really.

I bought this from a bike shop, choosing it over a couple of other types of courier bag on offer. It feels well-made but at the same time manages to be pretty light. It holds everything I need for work each day, as well as lots of 'just in case' items, such as a coat, sunglasses, phone charger, etc. It is simply one big compartment with three slim pockets along one of the inside faces. For me, the only way this bag could really be improved would be by having more pockets to organize my little items better, but otherwise this is great. It stays in place on my back really well whilst cycling.
