While not huge, the bag provides enough space for everything i need with me for the office.
The bag is very comfortable , despite my larger frame.
Very sturdy build, and definitely unique looking.
Get many compliments on the bag, and people asking where to get it.

Had the bag for about a month and at this point it seems durable and well thought out. Heaps of pockets for your gear and convenient pockets for while you have the bag over one shoulder to get to your wallet or whatever. It is a good size day bag but unfortunately that is it there really is not enough room in the bag for many clothes so not really an overnight bag but as a day bag it is great.

I bought jay through the kickstarter campaign and haven't looked back since. It has to be the most practical city pack for outings with computer, running errands, dropping things off, buying small items, just having your bike gear with you without even so much as a thought ...
the inside compartments makes arranging things easy, it protects an A4 envelope beautifully if needs be, the lid is super fast and safe, it's water resistant even in northern German weather, the pack is sturdy and doesn't cling to your back, and the outside stretch pockets are just brilliant for bike gear, your glasses, a small bottle - things your need with a flick of a wrist ... not to forget the hidden pouch for you purse or passport or so.
it really is one of the most thought-out, incredibly well-made and sturdy products I am using. I cannot recommend this thing enough.
