A substantial number of these helmets are returned because of sizing issues. PLEASE MEASURE to be sure your head circumference does not exceed { 23 in | 58 cm }.

The LM Diving Helmet is lightweight and low-profile, durable yet comfortable and available in a wide choice of colors. The helmet shell is an injection molded high density polyethylene (HDPE) suspended over an adjustable inner suspension cradle, similar to a construction helmet. It features nine ventilation holes on the top and sides to release trapped air and has no foam lining that would make it overly buoyant. The adjustable chin strap is fashioned from soft nylon webbing and has a quick disconnect buckle for easy fastening.

The LM helmet adjustable suspension cradle fits most heads with a circumference from { 20 to 23 in | 52 to 58 cm }. Only one size is available, and it does NOT fit everybody, so we recommend you actually measure to be sure of fit before you order. Some divers, using the helmet solely as a mounting platform, remove the suspension cradle altogether and use a thick hood for spacing.
