Quick sizing question! I've scrolled about 50 pages of this thread before calling it quits but is there a significant size difference between m and l? I tried on both, loved both, but only have room for one. My current everyday bag is Lv pochette metis, and I'd love the 19 to replace it. I really do not carry much (long wallet, airpods, chapstick, phone). Would a medium with an organizer inside fit my items comfortably? I'd also like to carry my ipad- for travel, so not often or long term. Would the large be better worth my money? Again, ipad carrying would be maybe 4-5x a year. My pochette metis does not fit my ipad so usually I swap bags to travel but I'm hoping this 19 would truly be my everyday bag. Thanks in advance!
