Sentinel™ Series Boat Crew Dry Suit



MAP XS-3XL $1,925.40

Retail $2,217.45

Mustang Survival's Sentinel™ Series MSD637 Boat Crew Dry Suit with drop seat optimizes fit, comfort and functionality which are extremely important, especially when a poorly fitted suit can impede on a mission's efficiency and your safety. Validated by the US Coast Guard, NAVAIR and the SAR Model Manager Office, the Naval Special Warfare, and swift water and ice rescue instructor and trainers, Mustang Survival Sentinel™ Series is designed to be compatible with all types of equipment used in these environments.

The MSD637 is a waterproof and breathable constant wear boat crew dry suit ideal for Law Enforcement and Search and Rescue (SAR) small boat operations where crew members don't intend to enter the water but require hypothermia protection in case of accidental immersion.

This standard boat crew dry suit is ideal for regular duty and provides 1050 Denier Ballistic Nylon reinforcement in high wear areas such as the knees, elbows and seat.

Exclusive to Mustang Survival, the Sentinel™ Series Dry Suits feature:

  • Mobility Based Sizing™ offers users a semi-custom size fit that reduces bulk and increases mobility without the custom price tag.
  • Rapid Repair Technology™ enables users to rield replace neck and wrist seals and repair small leaks in an hour or less.

Thermal performance of the MSD637, as with any dry suit, is dependent on the type and thickness of the undergarment worn. Mustang Survival's MSL601 Dry Suit Liner is the perfect companion for the MSD637.
