Air-Mod MSS Compression Dry Sack — an upgraded compression and waterproof carry solution for Modular Sleep Systems and Rifleman sleeping bags. Unlike a conventional MSS compression sack that relies mainly on external straps, the Air-Mod design adds a manual one-way purge valve. After loading the sleeping system, the user presses trapped air out through the valve, closes the system and tightens the straps to maintain a compact field-carry profile.
Sack only: Sleeping bags and sleep-system components are not included.
Key Features
- Manual Air-Purge Valve: Releases trapped air while the user compresses the contents; no pump or powered vacuum equipment is required.
- Maintains a Compressed Package: The valve, roll-top closure and external straps work together to reduce bulk and help keep the packed sleeping system compressed.
- MSS & Rifleman Compatibility: Sized for complete USGI-style Modular Sleep Systems and compatible AKMAX Rifleman sleeping-bag configurations, subject to the selected component combination.
- Waterproof Dry-Sack Construction: Waterproof body, sealed construction and roll-top closure help protect sleeping bags, clothing and other soft equipment in rain, wet packs and water-crossing conditions.
- 82cm Field Size: Designed for bulky sleeping systems, insulation layers and mission clothing.
- Gear Buoyancy Support: When correctly packed and sealed with sufficient trapped air, the sack can help keep the enclosed gear package buoyant during controlled water crossings.
- Black Field Configuration: Supplied in black with compression straps and purge valve.
How to Use
- Load the sleeping system or soft gear into the sack.
- Close and roll the opening according to the dry-bag closure method.
- Press the contents to expel trapped air through the purge valve.
- Close the valve and tighten the external compression straps.
- Before water exposure, inspect the roll-top, valve, seams and closure.
