I met a number of happy backpackers between Harpers Ferry and Waynesboro VA this last summer who were carrying very compact Lafuma synthetic bags. They liked how small a ball the stuff/compression sac provided worked out. They liked the price, and they liked the idea that enough Lafuma dealers were up and down the trail that they could get warranty replacement.

I don't know if these are just the 2009 bags by Lafuma. I bought a real inexpensive Steep and Cheap . com Lafuma as a guest bag, last year, and it was unimpressive. Except it was probably worth the $38 or so cost I paid for it.

TheOutfitterAtHarpersFerry.com carried Lafuma 2009 bags and so did some place down in Damascus VA.
