compression sack as saddle bag

[yep]

hello all, first post and bikepackin newb.

has anyone sucessfully rigged a standard compression sack up to their saddle? it seems it can be done with some webbing straps and w/o too much diy sewing. maybe some stiffener if its a big sack, but i'm sure some webbing sewn in would be lighter. I'm inspired by the expensive rackless systems but not willing to shell out that kind of money. i'm looking for capacity cabilities that can also cinch down for commuting.

also, does anyone know of cheap frame bags with decent capacity. i saw the nashbar (cheap/small) and the jannd (bigger/more $). maybe a bit bigger--3/4 or full size road diamond. i might have to sew one.

someone gave me a nice road bike. bpl has taught me much about getting my pack light (3+ seasons 8lbs base with comfort). I didn't really want a rack. i'm glad i found this site. i think with these two carrying options and a little lashed to the handle bars i'll be set for touring and weekend bikepackin w/o compressing down too much. thanks for the suggestions.

I've strapped a Granite Gear XS compression sack under my saddle without having to modify it at all, and it was quite stable.

Making a full frame bag is fairly easy.

I think it would be fine and would do that myself but my Carousel seat bag just affords me the ability to carry quite a bit more food if need be.
