I've got a question regarding this backpack. I'm seriously considering this pack, but am still hesitant to get a pack closer to ~40L than this, especially since it'll be used for air travel. Without the brain attached, is it possible to compress it in any way so that it could pass as a carry-on for air flights? I feel like it might be, but in its normal shape it seems to be a little too big for official carry-on luggage.
Thank you, and any response is appreciated!
