Wave Barrier Technology
ISP’s range of bladders includes the unique patented interlock bladder design with Wave Barrier Technology. The design is the culmination of years of design expertise and knowledge working in tandem with test houses and approval bodies.
The bladder delivers a sub 5 second super-fast turn speed placing the wearer on their back with airways raised clearly above the waterline delivering maximum freeboard. The two lobes of the bladder overlap in the middle creating a resistant Wave Barrier keeping the wearers airways clear of the water and massively reducing the risk of secondary drowning.
In the 2019 Challenger range, ISP has developed a consolidated range of commercial marine workwear lifejackets which carry all the relevant approvals and accreditations. This gives our customers the assurance of safety when operating in demanding and often hazardous situations.
The interlocking lobe design used provides in-water protection by channeling water and spray away from the wearers airways, whilst optional AIS integration will increase your chances of a quick recovery, should the unexpected happen.
