Greggers wrote a question about Arc'teryx Silo 18 Backpack - 1098cu in on June 8, 2009
I imagine the HDPE frame sheet is removable; can anyone confirm this? I'm am looking to use the Silo as a summit pack, and will need to be able to fit this pack easily into my larger approach pack, so I would appreciate input on any other bulky features (such as foam built into the back panel).
Also, any word on how well it carries an ice axe?
Thanks for the help!
