I'm brand spanking new to the Tom Bihn family, became officially a part of the family with the recent arrival of my Synapse and an Ego for husband's birthday in a couple of weeks (shhh!). I must say, I'd looked at all of the pictures and comments about the Synapse and was a little skeptical about its capacity potential and overall wonderful-ness. I'd been looking for a Goldilocks backpack (not too big, not too little, just right) to use while flying with a small infant. Wow. I think I've found it! I'm so impressed and, I gotta say, usually my experience is the opposite- I find a bag that I think will be perfect for a certain purpose, I get it, and...disappointment. Not so with the Synapse. I'll let you know in a couple of weeks when I've actually flown with it and baby, but I did a dry run and- shazaam! Everything fit wonderfully with no bulk! (I'm hopeful the hubby will be equally thrilled with his Ego, but you never know with him.) Anyway, I'm starting to understand how y'all get lured into TB addiction and it got me wondering, which bag do I "need" next? In that vein, I'm curious to know what is your favorite TB bag or accessory?
