I feel almost obliged to post this after previous offers.
Again, this is an older model bag, but where available, seems to be >$100. E.g. Amazon, RushFaster
Two colour options: Black/Gunmetal/Algae Green (out of stock) or Dusk Blue/Pacific/Dusk Blue.
Similar to the popular Commute bag, but with an inbuilt Joey T1 power supply (13Wh, 5V, 1A).
Specifications:
Weight: 2.71 lbs (11 oz)
Dimensions: 32.5 x 44 x 15 cm
Volume: 18 litres
Maximum Device: 15"
It's a good deal - bought one of their bags years ago, still going strong - but who are the sellers and what cred can be attached to them as a business? There are no contact details - no phone, email, or business address.
