How to avoid back sweat from bags?
 

Are there any good bags that don't leave big sweat marks or are there any good ways to avoid this with regular bags?

i try and wear an undershirt, but it leaves that thing soaked. there is no real way to avoid it. although i have seen some bags with built in fans and junk.

because the sweat marks totally class with my outfit.

...yeah, the ones that contain a clean T-shirt you put on after you arrive.

The only way to avoid it is to not wear a bag on your back.

Those hip pouches are starting to look pretty good, huh?

those racks, baskets and panniers are starting to look pretty good, huh?

what it is.
i'm gonna put a rack on my track bike so i don't have to haul a lame ass mess bag around.

I've been thinking a lot about this. How about some stiff honeycomb mesh spacer that allows air to flow relatively freely, while still distributing the load comfortably. Nylon or PP would probably be suitable.

but there's still points of contact because of the strap. basically, if you're wearing cotton, no matter what's touching you, i think it'll leave a mark.

so. someone needs to make a floating bag.

The straps? They're too narrow to make a difference. It's the large area of the backpack itself that's the problem.

maybe it's just humid florida. i always have strap sweat.

dont wear a bag/carry a spare shirt. discussion over.

Or move to a city where it is always cold.

Dumbest thread....

Its kinda hard to not sweat buddy....

I get a sweaty back when it's below freezing and I dress light even on the coldest days. All the other things that will work have been mentioned: rack/panniers, clean shirt, hip bag etc... If you can fit your stuff in a saddle bag or handle bar bag those would be good options.

Smoke just started pouring out of the ears of a hundred and thirty two hipsters.

how about getting yourself a nice big front basket and some bungees, then you can throw your bag in the basket and strap 'er down...

Or to wrap yourself in plastic before you put on your bag.

you mean before you put on your shirt...

I have a back pack by Schwinn. It's supposed to have a sweat wicking bacing adjacent the wear's back. It does not work. Seems there is a new design that elevates the backpack above one's back. I prefer panniers.

whats worse than back sweat is when you dont sweat at all when riding, but when you go inside, you start complaining that its hot and then you start sweating bricks. makes you look very nervous and sketchy, like you are about to rob a place.

Hmm, I always ride in synthetic clothes that wick and breathe. Maybe you get sweat to a larger extent if you wear regular clothes.

The OP just said he didn't want sweat on his bag. He didn't mention clothing. I'd rather not have the plastic right next to my skin. Skin needs to breathe, you know.

i believe he meant back sweat as in sweat on his back not bag.
