I also like the multi-pack. No way in hell I’d be caught dead wearing that around town though! For city hikes it’s always the Jansport so I don’t look like a dweeb.
Last weekend the wife and I did a short hike into a coastal campsite for 2 nights. We didn’t think ahead to bring a day pack, so I tied some cord onto the lid of the REI Flash. Worked great.for a 6 mile beach walk. The other option was using the tent stuffsack but I think the zippered pockets of the lid were a bit more convenient.
