I thought I found the perfect pack then discovered it has an internal aluminum brace.Will this be a problem on planes, trains, and other forms of public transport? Thanks, Scott
Scott, what do you mean by "problems", do you mean security? If you check you bag on the flight is won't be a problem and on other types of public transportation including trains it won't be a problem either.
My favorite travel pack also has an internal aluminum frame. I'm trying to think how it could be an "issue." I guess it adds a little weight and bulk but this is minimal. It's rare to find a small internal-frame pack, and if yours is large that could be a problem for you from the "pack light" perspective. Large packs encourage sloppy packing, are awkward, and increasingly do not meet carry-on requirements. If so that is a problem with size not with the internal frame.
scott, It would help to know which Pack you're considering? Most of the travel packs from Eagle Creek, Osprey and other manufacturers have an internal metal frame. In my experience this has never been a problem (except of course for the very slight extra weight). Cheers!
So...what pack is it?
Are you carrying on? The weight may not be a big deal but the frame will make it less flexible so you need to be sure it fits carry-on limits. The frame carries a lot more comfortably than what I use, but I've yet to find a true backpack that works for airline carry-on - they're usually longer than 21".
