:: Features

• Three Layer System:
  • 1st Layer—Thermal Layer
    • This layer uses ultra-soft, polyvinylchloride (PVC) closed-cell Comfort Zone™ foam to provide exceptional thermal protection and inherent buoyancy. It is also designed with Hydro-Vantage™ quilted wicking fabric, which pulls moisture away from the body, ensuring a dry, comfortable fit.
  • 2nd Layer—Immersion Module
    • This second layer of protection provides a waterproof barrier. Using GORE-TEX Best Defense® fabric provides a waterproof, windproof, breathable layer which reduces heat stress and fatigue, while maximizing thermal and immersion protection during long operations. This layer also has Closed Comfort System (CCM™) neoprene wrist seals and a patented adjustable neck seal for improved comfort and fit.
  • 3rd Layer—Outer Shell
    • Using durable 210 Denier Polyurethane-coated Nylon, the shell is designed to protect the inner layers against debris and other abrasive materials. Additional features include Advanced Ventilation Technology (AVT™) venting design, which promotes heat and moisture regulation, and reinforced seat and knee panels using 500 Denier Cordura® Nylon to maximize work suit longevity. An inflatable pillow adds head support and improved freeboard, while SOLAS/IMO reflective tape provides high visibility.
• Benefits
  • Performance × 3
    • The individual properties of 3 modular layers are integrated into one unit to provide optimal protection while offering simpler repair or replacement of parts.
  • Immersed Clo 0.74
    • Evaluated for hypothermia protection, the MSD900 provides an estimated 6 hours of survival time in 32°F water, rating an Immersed Clo of 0.74 (based on a thermally insulated mannequin).
