Still using my 2 Timbuk2 messenger bags. The first one is an original medium ballistic nylon one that has had some serious use since… 2002, and is still virtually unmarked on the outside! This is used for everything not laptop-based. It looks similalr to taoday’s offering: https://timbuk2bags.eu/products/1108-classic-messenger-bag-europe?variant=32387783098506
The second one is a dedicated laptop messenger (Command/small - TSA approved, but now discontinued) which I bought from the Timbuk2 shop in SanFran in 2010 and has had daily use, although a bit less in the last year. Still looks spotless.
They’ve provided carrying stuff for a combined total of 30 years (!) so far and look like they can easily do the same again. Bomb-proof these things.
