Mustang Sentinel™ Series Dry Suit Liner - Black - XXL

The Mustang Sentinel™ Series Dry Suit Liner in black XXL is a cold-water thermal undergarment engineered for extended immersion operations, water rescue, maritime patrol, and tactical diving applications. Constructed from a hybrid blend of Polartec® Classic 200 fleece and Polartec® Power Stretch materials, this dry suit liner delivers substantial insulation in water while managing moisture and thermal burden during surface intervals and recovery operations.

The dual-fleece construction combines the warmth retention of Classic 200 with the elasticity and moisture-wicking properties of Power Stretch. This hybrid approach allows the liner to move moisture away from the skin surface toward outer drysuit layers for evaporation, reducing the risk of chilling during submersion and preventing the thermal dead space that occurs with standard single-material liners. The fabric composition is specifically designed to perform at temperatures where active water exposure is extended—typical for rescue operations, military water insertion, and commercial diving scenarios. Sizing at XXL accommodates larger frame operators without sacrificing mobility or creating compression points under the outer protective shell.

This liner is purpose-built for maritime first responders, water rescue teams, naval personnel, tactical divers, and cold-water recreational users who require reliable thermal protection as a component of a complete drysuit system. It works as a mid-layer system when paired with Mustang Survival or compatible drysuits, providing the thermal buffer necessary for survival-time extension in cold water environments. Operators working in northern waters, open ocean, inland rescue operations, or winter training benefit from the predictable insulation performance and the reduced fatigue associated with proper thermal layering. The Sentinel™ Series is not a standalone garment but rather an integrated thermal component designed to maximize the protective envelope of a drysuit.
