Gday, I've been researching a few day packs, most based on the forums posts (thanks), for my Kokoda trek in March 2010 and have found a few I like,
Deuter Futura 32L
Macpac Torlesse 35L
Osprey Aura 35L

I'd most likely buy the same pack in a larger model for my porter.

Have any of you fellow trekkers had good/bad experiences with these pack?
Or are there any others worth considering?

Cheers
