The Crewfit N190 immersion suit is a lightweight alternative to the neoprene suit. Providing over 140N of buoyancy enables the suit to be worn without a lifejacket, an attached buoyancy pillow supports the wearer when floating face up.  Crewfit immersion suits are made from fire retardant fabrics to provide good insulation and resistance to oil, sunlight and seawater.  All seams are stitched and taped to ensure they are totally waterproof. Critical areas are taped for additional reinforcement and the foot sole is reinforced.
