inexpensive and very handy note helmet size

This winter kit of Abus fits very well and practically in the helmet. Above the ears and the back is slightly more padded, top left and top right a little thinner.
Unfortunately, a washing instructions missing.

This Abus-cap of the helmet should be 3 to 4 cm larger set than the normal head circumference.

The ear pads for Uvex discovery were to demand not available at a dealer.
The under-cap of KED currently costs twice as much.

In addition or instead you can look at the Earbags ear warmers.
