I've used a Chrome messenger bag before. I've used a military surplus pack for many years, off and on. Hiking/hydration packs as well. I am looking for something specifically for commuting: carry my lunch to work, bring stuff home, small grocery runs, get the mail, library stuff, etc.

I am avoiding racks and bags on my SS/FG. So we can omit that option.

I welcome ideas and suggestions.

I bought this one not too long ago in large ...

wiggle.com | Osprey Radial 26 | Backpacks

It's petty nice, especially the frame that keeps it directly off of your back.

I carry an assortment of tools, a reflective jacket / windbreaker, a change of clothes, 2 tubes, small chain lock, small pump, bottle of water, and a small laptop.

I wish it were bigger sometimes, there's also a 34 version.

Do you need waterproof? Mission Workshop are good waterproof bags, lightweight, but pricey. I have the sanctrion and like it a lot.

Some Dueter cycling backpacks are supposed to breath better on your back.

I like the quality of Osprey as well, I have one for work. They have cycling specific packs.

Ortlieb and Seattle Sports also make waterproof dry bag backpacks.

the I got a ... thing is the usual reply form, so:

(I got a Seattle Sports one 30 years ago thru REI, rebranded for them, It is my Mandolin case cover with back pack straps.)

My other one just as old is Dana Designs, they still around?, the pack is still good.

I have had this bag for years:

Large Commuter Backpack | Banjo Brothers

Waterproof, bombproof, replaceable inner liner and it still looks like new. If anything ever happened to it, I'd buy another one in a heartbeat but I just can't seem to wear it out.

I have the Large Banjo Bros backpack and it is a top-notch product. Great reflective strips.

I have seen the Osprey Radial in the store and I was impressed but I didn't need another backpack at the time.

My daily backpack is a Timbuk2 Swig which I love. I got a custom where I spec'd a huge reflective panel for safer nighttime riding. I think the Swig is discontinued but Timbuk2 has several bicycle backpacks to choose from, most or all customizable.

I love commuting with a backpack, but I am blessed with 3 mile commute and mild weather year round.

Backpacks are like bike seats...very personal. This is what I have been using for the last four years:
Swiss Gear Scansmart SA1696
Swissgear seems to make a few basic designs with many variations there of. What I most like about this one was the pocket layout and internal storage configuration was similar to my previous Eastport backpack, only bigger and sturdier.

I'm putting in another vote for Osprey as well, in this case an Escapist 32. I ordered it online from REI after reading an article from Bicycle Times. It has tons of room, and can be cinched down when you don't need all of it. I use it for everyday commuting, and on the weekends load it up full with gear (helmet, shoes, sunscreen, snacks, ect) for roadbiking trips. Just toss it in the van and everything is right there. It comes with a waterproof hi vis cover too.

I use the Ortlieb messenger backpack and I can testify for its one quality that was the one quality that made me buy it. It is indeed totally waterproof. I must have that because on many days the bicycle is my only reasonable method of transportation, and if it is raining I have to go no matter what. Its "negative" points are that there are no external pockets, and no place to clip one of those little blinking lights, if one has a need for those features. I myself do not. The only really annoying feature is that it is so deep and so dark that if I want to find something that has migrated to the bottom I almost have to put on a headlamp and dive in head first. But that is minor. I do like it, and if it ever wears out (seems unlikely) I probably would get another.

I have an Osprey Momentum 34 which works very well for me. It's no longer available but they have several similar models. Lifetime warranty with excellent customer service. Hard to go wrong.

I think I am going to get a Momentum 26.

Or maybe a Radial 26

I've got a couple of packs that I've picked up over the years.

The Swiss Gear packs are good. I like having lots of pockets

A few more reflectors would be nice.

I also have a Camelbak Mule that I picked up. The bladder went bad, but it is a great pack when I want something small. Just a few tools and supplies. Plus it does expand somewhat for those moments I need more than I had expected.

Thanks for the replies. I have a handful of Osprey packs, plus a Nathan running pack. Isn't there a commuter/messenger pack by the name of Trashcan or Garbage Can or something like that?? Gotta go google that one....

The white piping is reflective, but I added reflective tape to it for more visibility.

Trash bags

Just what I need, to carry an armoire on my back

Are those even designed to be filled up?

I've used a couple of different backpacks over the years and find that the ones with the copression straps are the most flexible. Good the days when the load in and out are different.

I have a 2013 Timbuktu Uptown and my work just gave out new back packs and I have the new model. Both were gifts from work so I didn't shell out $ for them. I'm happy with the quality and they are sturdy. Also hold a 15" Macbook Pro with no issues. Decent padding between my back and the laptop. Lots of zippered compartments. But as with all backpacks, I'm a sweathog after my 22 mile commute.

I switched to this patagonia lightweight travel tote, it is superlight and I am happy with it so far. I used to have a Osprey momentum 34.

You don't say how large/small it needs to be. It's always a compromise. This is a cheap, <$20, "wallyworld" backpack.

Cross country? No. To and from work? Sure. Depends on what you need.

That's a nice gift!

Question, for those using backpack, how do you deal with sweaty backs? Do you just accept it or does your backpack's design keep your back from being over sweaty? I know that's the reason I went with a rack. I couldn't stand the extra sweat caused by my backpack.

I have had good luck with the Performance Bike "TransIt Torrent Waterproof Backpack" Basically a dry bag. Low cost

I don't mind the sweat. I do have a shower at work though.

Yes, and people do. Here in NYC, bicycle is often the fastest way to deliver goods, so people use this and other interesting ways of carrying large volumes of stuff. Having it on the body makes going over bumps easier if you have a light bike. And it makes locking and unlocking the bike quicker because you're not moving cargo between body and bike. Bicycle delivery people are seen everywhere I go in the city.
