Certified 150N Inflatable Lifejackets – Exceptional Ergonomics & Marine Safety

A 150 Newton inflatable lifejacket (certified compliant with EN ISO 12402-3) is the proven benchmark for adult boaters, coastal cruising, leisure angling, and light commercial marine tasks. Unlike bulky foam buoyancy aids, an inflatable lifejacket is lightweight and unrestrictive, ensuring unhindered freedom of movement while worn over regular outdoor clothing or light foul weather gear.

Upon accidental water immersion, the automatic hydrostatic or dissolving cartridge deploys within seconds. The inflated bladder delivers at least 150 Newtons of positive buoyancy, engineered to self-right an unconscious person onto their back and maintain clear mouth and nasal freeboard above the surface.

• All-Day Comfort: Ergonomic weight-distributing harness designs with soft neoprene or fleece neckliners that prevent chafing during long watches.
• Gas Cylinders (33g & 38g): While generic 150N vests commonly use 33g CO₂, Mullion's models (such as the Compact 150, Compact Supreme, and the 195N series) are engineered with superior real buoyancy (up to 172N–195N) and utilize 38-gram CO₂ cylinders. All feature standard 1/2"-20 UNF marine threading.
• Essential Safety Hardware: Fitted with marine-grade whistles, lifting becket loops, high-intensity SOLAS retroreflective tape, and crutch strap attachments.

Heavy Clothing Notice: If operating with heavy industrial foul weather gear, floatation suits, or tool belts, explore our 275N Commercial Lifejackets to guarantee correct righting performance. For replacement cylinders and maintenance bobbins, browse our lifejacket re-arming kits & spares →
