Zefal paikkaus spray 100ml
No need to remove the tyre when you puncture.
Just attach the hose to the inner tube valve and press the button.
Seals holes up to a 2mm diameter (the size of a large thorn).
Carry this on your commute along with a spare tube, you might never have to use the tube.
103g - weighs less than most tubes - can't think of a reason not to carry the can.
