The pads make sure that the inside of a helmet is moisture free and absorbs a good amount of heat as well, they should be removable so they can be washed easily. Further adding to this, you should also check the material of pads and make sure that they are skin friendly.

Although there are some helmets which have magnetic clasp for quick installation and some have plastic clasp which are much lighter and less obtrusive in comparison to others.
