Mustang Sentinel™ Series Dry Suit Liner - Black - Small

The Mustang Sentinel™ Series Dry Suit Liner in Black, Small is engineered for tactical personnel, military operators, and cold-water professionals who require reliable thermal protection during extended aquatic operations. Built by Mustang Survival—a trusted name in marine safety gear—this liner addresses a critical gap in cold-water readiness: maintaining core body temperature and mobility when operating in frigid conditions. Whether deployed for swift-water rescue, amphibious insertion, or cold-weather maritime training, the Sentinel Series delivers the insulation and moisture management professionals demand when thermal compromise means mission failure or worse.

This dry suit liner combines Polartec® Classic 200 fleece with Polartec® Power Stretch fleece—a hybrid construction that maximizes both insulation and freedom of movement. The Classic 200 provides efficient thermal retention even when damp, while the Power Stretch component enhances dexterity and reduces bulk without sacrificing warmth. Polartec fabrics are engineered to wick moisture away from skin and retain heat in wet environments, a critical difference from standard fleece. Weighing only 1.25 lbs, the Small size (14 x 1 x 20 in) minimizes packed volume for field deployment while maintaining sufficient thickness for meaningful thermal protection. The black colorway offers low-visibility characteristics preferred in tactical and law enforcement applications.

First responders, military dive teams, and cold-water rescue personnel rely on this liner as a base layer beneath dry suits or wetsuits to extend operational endurance in water temperatures below 60°F. The Small sizing accommodates lean and standard builds, providing snug fit without compression that restricts blood flow. The Sentinel Series functions optimally when layered inside a dry suit—the outer shell protects the liner from abrasion and wind, while the liner's moisture-wicking properties prevent the clammy sensation that degrades performance and morale. For teams operating in Pacific Northwest waters, northern lakes, or winter maritime environments, this liner is non-negotiable thermal insurance.
