pisspot helmets are good because they can be hit over and over again without needing to be placed. their cheap. they cover the vast majority of you head they dont have many ventilation holes in them so you generally get hot quicker. their also heavier. alot of riders use a xc style helmet as their light and keep ur head cool i always found their much more adustable than pisspot helmets. but your meant to replace your helmet if you hit/knock it. i have a cheapish xc style helmet because i think it looks better than a pisspot and it wont cost much to replace. it doesnt really matter what helmet you get, as long as it fits and protects you head
