For Sale: The Packa. Green size Medium X, recommended size for larger packs, such as a ULA Catalyst, external pads, etc. Like new, packs in its own pocket. Works great in the rain, has pit zips, easy on and off, keeps straps dry, but decided to stay with my rain jacket. New $125, yours for $80 shipped or best offer. Paypal, Conus.
