Built around your spine Here’s what’s inside
A heated panel, a memory-foam lumbar pillow and straps that move weight off your shoulders, inside a bag that looks like any good work bag.
Three levels of heat Tap one to try it
Coils run across your upper, middle and lower back, so the warmth covers the whole panel instead of one hot spot. Heat helps loosen stiffness and ease pain while you walk, ride or wait for the train.
Heat is on medium.
Powered over USB-C. Plug in at the port on the bag. The button beside it turns the heat on and changes the level.
Every strap has a job
Tap a point on the bag to see what it does for your back.

Clavicle pads
Extra padding sits where the straps cross your collarbones, so the load spreads out instead of digging into your shoulders.
By the numbers
Big enough for a laptop day, small enough for a crowded train.
