Alright, so it's been blazingly hot in Boston, and it doesn't take much for my back to get damp with nothing on it, let alone my Crumpler Seedy Three loaded with a bunch of random crap. This is not a thread about avoiding a sweaty back. My issue is that when I do get sweaty, it tends to seep through the lining of the bag and dampify my random crap. I could just throw a towel or something in there, but I don't really want to add more crap. The funny thing is that the bag has been through several torrential downpours, and nothing inside got wet. I guess it's the close, prolonged contact.

I've been pondering a new bag lately, so I was wondering if anyone knows of a bag that doesn't have this problem. I like the Baileyworks bags (as do a lot of people here, apparently). Any opinions?

my back sweat and chest hair stay out of my chrome bag. a severed head does not. oops...

That shouldn't happen to any waterPROOF bags; Chrome, Bailey, Reload, etc. I didn't know that Crumpler doesn't qualify for that list. Are you absolutely sure that what you described is actually what's getting your stuff wet? Ever keep cold drinks in your bag on a hot day?

second the non-sweaty-inside on the chrome.

There's no reason your sweat should go through any sort of real liner. I guess the crumpler doesn't have one.

I have a seedy three, I've used it every day since last november or so, rain or shine. I've ridden in serious rainstorms and my gear has stayed totally dry.

I'll second the cold drinks on a hot day.
...or maybe your back is just exceptionally sweaty...

Well, today I did have a cold drink in there, so that probably didn't help, BUT this is not the first time this has happened, and it has happened without any sort of beverage.

I have a random crumpler messengerish bag that a tenant left in my apartment building. I have the same problem. But I'm not surprised seeing as this particular bag is neither waterproof or made specifically for cycling. Is yours advertised as waterproof?

well...you can get moisture on the inside of anything. If the object that is in the bag is cooler then the air around it. Condensation happens...especially with high humidity. No bag is moisture free unless it is in airtight/watertight condition.

It is the prolonged contact combined with body temperature and ambient heat causing your bodily juices to wick through the fabric of the bag. Any bag with a PVC lining will prevent that. Also try to be sure your new bags outer layer is nylon to prevent stank.

No, condensation happens if the surface is below the dew point. The inside of the bag is probably not below the dew point.

I have a Bailey Works (as you know) and am probably the sweatiest person I know. No problems.

You could try the spray-on waterproofing. Works great on my cheap-o hiking boots. And it's not too permanent if you don't like it. But remember that your back will probably be twice as hot/sweaty since that stuff blocks any air flow as well.

Ah yes, the requisite "if it hurts, don't do it" reply. :) Although, I'm right up there with bostontrevor in Squaresville, with my helmet, front and rear lights, brake, clipless pedals, and occasional fender. Why not just go for the rack to complete the package?

why not get a plastic garbage bag and use it as a liner? or maybe cut one up and tape a plastic piece to the inside surface that touches your back?

it would be ghetto fabulous, but it would might work and probably would cost very little

It was 100+ degrees in Denver the last couple weeks, so I put a basket on the front of my commuter.

That bike would look downright silly without the basket. It's a keeper.

I rock a rack and 3 bottle cages, one of which hose-clamped to the frame along with a canti front brake, and clip on lights. w00t!

My brown XL Bailey is going to be for sale pretty soon I think. Quite used, but not abused. Nothing "wrong" with it, just a bit dirty. If you're interested (or anyone else on here) shoot me an offer. I just want two straps, so I think I'm going to go ReLoad.

Yeah. I just bought this:

So someone should offer me something for my bag. It's big and works if you don't have a bad shoulder.

Baileyworks passed my sweat test in the boston heat. 8 hours on wednesday, a little over 6.5 liters of liquid drank, much of it sweat back out.
