Much bigger than you are looking for. I have used it as carry on luggage, on day hikes, and sometimes pack it in my suitcase on business trips where I can use it for quick little trips, either a day hike or a quick overnighter.

Jonathan,

Here’s a myog version that can be easily taken apart and stowed. It fits into a bag about the size of a tent pole bag. Much bigger than you need.

I have a Sea to Summit stowable silnylon pack that weighs 2.5 oz (my scales) and is a pretty small volume. should be perfect for your purposes.

I also have the sea to summit, it's ideal for me…fits in a jacket pocket.
It's not exactly the strongest but for light items it's great. I can put a fleece or similar in the bottom and then some water and a snack above.

Here's a small, "packable pack" from Eddie Bauer (1036 cu. in. claimed) with a lot of features (two mesh bottle pockets, zipper exterior pocket, interior pocket, and bungees on front) —

The above pack is fully priced at $29 currently (sometimes it's on sale for less than $20). Its features differ a bit from the REI Flash (including "flashier" color options — UGH!), but both have a lot of good reviews. I'd probably go for the REI Flash at its sale price.

But then I already have too many small packs!

I have the same one as Nick's, except in a different color.

Well, aren't I silly? I knew what I wanted had to exist, but my searches just weren't coming up with anything good.

I think the sea to summit pretty much nails it. The other ones are great, and I like the Marmot Kompressor, but for packability, the Sea to Summit wins. It will spend more time packed away than in use.

Thanks all for the great suggestions! If a mod wants to move this to the gear section, that would be fine.

Arc'teryx Cierzo 35 is the most durable of the stowable packs it stores in it own lid and weighs only 20 oz.. I tried out one for few days and returned it because of lack of pockets on the sides for my 1 liter platys,I also could not get all of my equipment in it for weekend trip.It is a great day pack that will last.

You could also make a simple draw string closing pack that folds in to a inside pocket yourself.

The Gossamer Gear Riksak might do the trick.
