From real operational experience Northwall designed helmets for pilot’s, technician’s and rescue personnel. Each product has unique features.
The LMT helmets provide the greatest possible protection thanks to innovative materials and solutions. There are 3 models available, LMT-Pilot, LMT-Tech, LMT-Medic.
LMT-Pilot
This helmet is designed for use by the flight crew, pilots, and others that mainly stay on board and require protection of the head during all phases of flight. The shape and materials used in construction allow the LMT-Pilot helmet to minimize the weight and size of the helmet without giving up all the security features required for flight helmets. The reduced size and weight allows the user to maintain long-levels of attention and not alter the balance of the pilot or create neck and shoulder strain.
