It can be done!

Came across this over on packlite and could not resist sharing:

I have an REI Flash 18 bag from a couple of years ago that I've brought along on a few trips. It's a bitty little bag and certainly not everyone's cup of tea (no structure, minimal padding on straps, top loading, etc.). Still, it gives one an idea of how one can get away with using a ridiculously small bag, depending on the nature of the trip.

I am tempted to try this the next time I do a short trip.

(Specs on the Flash 18 for those interested: http://www.rei.com/product/827110/rei-flash-18-pack)

Errr... That would be 4 DAYS, 3 NIGHTS.

It's been quite a day here. Apologies ;)

Ive got three generations of the flash 18 and like it for my uses.
One thing about that admirable packing list of his, its easier somewhat is the work/conference is casual vs formal. Esp if he wore those keens to the conference and either the same pair of khakis or shorts. Wish i could do that.

I have something similar but not REI.
Last year I used my Healthy Back Bag (Big Bag). Stopped in London enroute to Spain to complete a shopping list from my family. I soon realized I needed another bag and picked up a small fold up back pack from the Muji store. Same material, unstructured and no padding. It was a Tardis and held everything.
I also found it quite comfortable to carry, as without structure, it moulded against my body nicely.

It's definitely worth trying out Coco.
