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.
 

Performance X 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).
