Brand new survival system in the bag Mustang Survival Suit MSD901 SO (Complete 3 part system) - M - BLK - Brand New. Outer Layer - A protective outer layer is critical in cold and stormy weather and during activities when you will be or are likely to be submerged. Out of the water, dry suits, jackets, and bib pants prevent wind and rain from penetrating your inner layers and causing dangerous temperature drops. In the water, dry suits alone prevent the cold ocean water from getting in. Fabrics like Mustang Survival’s Marine Spec BP and Marine Spec SP make excellent outer layer choices. Their water and windproof capabilities while remaining breathable are essential to keeping you comfortable during high-intensity activities. Dry Suit Layer Manufactured and tested for performance at the Mustang Waterlife Studio, our Men’s Dry Suits offer reinforced waterproofing protection to boost confidence in all conditions and extend your time on the water. Thermal Layer Designed as part of a full thermal management system, these base layer are constructed for optimal compatibility with Mustang Survival dry suits. Offered as a two piece set made of the highest quality Polartec® materials to provide utmost flexibility based on mission profile.
