Here is a fruitful project between SAG, the renown Japanese bag label and Mash SF who need no introduction. With no detail left aside this is a very thoughtful bag, this timeless backpack has been produced for the bike. Amongst the features there is the addition elastic so you can tuck any extra webbing, the back/shoulder pads let air between the bag and your back when tucked which are also removable so you can wash them.

The top handle is soft, while the way the back pad/shoulder straps work you can adjust how high or low you want the bag to sit on your back. Classic clear window unfolds and holds the tail of a skateboard, and skate straps pull out. Finally a thermal pouch, all seem very minimal but make a huge difference when out there on your bike, while the things I really appreciate about this piece is the subtle charcoal SAG logo which is reflective for a great touch and the artwork on the interior completed by the people at Cadence.

Thanks to Mike Martin for the info.
