Advice on laptop/overnight bag
I'm interested in purchasing my first Tom Bihn bag!
I currently have a Booq Boa 3 bag which I love, but it looks like I'm going to need some more space.
I travel frequently to HK/China, but now it looks like I may be living in HK for a couple of months and will be traveling back and forth from China very frequently. And I will be staying overnight 2-3 times a week as well.
As a result, I'm looking for a bag that can hold my 15" Macbook Pro, mouse, power adapter, and a change of clothes and toiletries. Maybe even shoes and umbrella, and my 32 oz Nalgene would be nice as well.
I'm thinking Brain Bag or Western Flyer + Brain Cell + Freudian Slip (too bad Brain Bag won't fit 4Z horizontal Brain Cell, I'm not a fan of the vertical orientation Brain Cell but could deal with it), but am open to anything really. I prefer bookbag vs. shoulder style, shoulder bags always kill my shoulder. Maybe I'll throw a Snake Charmer and a couple of accessory pouches as well.
Would also like it to fit under the seat for flights if possible.
Thanks for your input!
