Does this pack have an internal frame? Would it be good for travel? I am looking for a bag that will work for 1 or 2 weeks, up to 6 months. Have you used it as a carry-on bag?
I have used this as a carry on without problems on a few 3rd world airlines
This bag is carry-on size--it's actually super nice for carry-on as the back pack straps tuck away making it more like a brief case (there is a side handle for that purpose).
I'm confused by your 1 or 2 weeks, up to 6 months request. There is no bag in the world that will be great for 1 or 2 weeks AND 6 months. 6 months is a long time. That said, I know plenty of lightweight travelers who can live off of 1-2 weeks worth of stuff for a 6 month period--is that what you mean? You can fit several changes of clothing, an extra pair of shoes, toiletries, a book, a laptop, and a water bottle.
There is no internal frame but the backpanel is slightly rigid so it holds its shape really well.
