What bag do you use and what do you carry in it?

I have had a Victorinox Swiss Army bag made out of some type of Cordura for over 10 years. I am very close to it. It has a nice padded carry shoulder strap, which is actually getting some wear on it.
It has my laptop along with invoicing, mail, payments and notes for projects I am working on for my business. It has been to many meetings, band rehearsals, clubs, bars and coffee shops. I do bring it home every night as I need the laptop and work on billing/scheduling etc.

I also have my normal assortment of things. A LED flashlight, multi tool, flash drive, business cards, Altoids, hand sanitizer, I hate getting sick and protein bars.

I had to have the zipper replaced as it came off and a local Victorinox dealer fixed it for free. Mostly my fault as I had my bag packed too tight to full of stuff.

A nice leather bag would be cool but it would get pretty heavy to have the same type of compartments as I have now.
I'm cool with the black.

I've been carrying around my Gustin Duffel in Waxed Olive as a gym bag.. it's lightweight, durable, and doesn't smell funky even after using it for a few months as such. I use a Jack Spade messenger for work.

I have a cheapo backpack for my motorcycle rides.

I have a 9$ cotton beach bag from polo for the beach of course.

Gustin duffle is awesome but I use it for trips and vacations not daily use.

I wear my gym clothes to the Gym and don't change there.

I don't carry a laptop.

I really have no use for a daily bag.
I carry my lunch stuff from my car 25ft into the work fridge that's it.

I use a Victorinox Swiss Gear laptop backpack for pretty much everything, but I've been looking for a change lately. I carry my instrument, music, notebooks, etc. to concerts and rehearsals, as well as my go-to carry on for travelling. I've been looking for a briefcase style bag for my music stuff that's wide enough and without dividers that won't break the bank, so I'm curious about the new G bag.

I have a Timbuk2 messenger that I use to carry my laptop, notebook, and books. Looking to replace it with something casual, yet more refined. Depending on the price I might go either Gustin or just pony up a few more green to get the Filsons.

Here's a marketing pic of the Jack Spade I use.. it's a nice bag. The stitching on the Velcro that keeps the front flap down started to come apart after two years of use.. this can be fixed, though:

I haven't used a bag since college. If I were to buy one it would probably be a waxed canvas shoulder bag I would use for my outings with my son. I currently use a cheap Eddie Bauer/Target diaper bag but one of the flaps is torn and I feel stupid carrying it. I'm thinking either a Filson on sale or maybe something cheaper, like a waxed canvas bag from Manhattan Portage. I basically only need a bag that's big enough to house a spare change of clothes, diapers, snacks and my personals
