Chainsaw helmets have safety visors to protect against flying debris and also offer hearing protectors to prevent damage to the ears from the loud operating noise of the machinery. Visors are adjustable and provide good visibility including during wet conditions when the rain water will run off quickly. Hearing protectors are adjustable both vertically and sideways ensuring that all loud noise is eliminated in a comfortable manner. As with all helmets weight is an important factor, they are lightweight and easy to wear without compromising safety measures.
A good climbing helmet offers good ventilation around the top of the head and a comfortable chin strap which can be fully adjusted, so once on the helmet will sit comfortably and offer the essential protection needed. Ventilation is generally adjustable so that the holes can be varied according to conditions. Climbing helmets also have fixings for optional headlamp, ear defenders and visor or face shield.
