The new Atomic Troop SL MH is our super-progressive helmet for skiers looking to bring a little Marcel Hirscher to their own slalom skiing. The Half ABS Hard Shell with its iconic graphics is definitely a Marcel favorite. It has size adjustment so you can fine-tune your fit at the back of the helmet, and comes with a SL Chin Guard included. On top of that, the visor and ski goggle retainer can be removed. And passive ventilation helps you keep at the right temperature even in the heat of battle.
