Size large. Purchased in March 2008.
This is a really great pack, and I may end up regretting this, but . . . . I'm putting all my eggs in my Aarn basket.
I've only used the Baltoro on a couple of overnights to test it out. It's very comfortable and sturdy.
4638 cu. in.
$289 at REI, plus shipping.
I'll sell it for $250 shipped in the 48.
