Collection: Modular Sleep Systems

Modular Sleep Systems, MSS Sleeping Bags and Bivy Covers

AKMAX supplies modular sleeping systems, individual sleeping bags, waterproof bivy covers and compatible field components for defense contractors, tactical distributors, training organizations and outdoor wholesalers.

Modular Sleep System Lineage

The military modular sleep system concept combines climate-specific sleeping bags with a weather-resistant outer bivy and compression storage so users can select or layer components for different field conditions. This collection includes USGI-pattern MSS configurations, patrol and intermediate cold-weather bags, bivy covers and AKMAX-developed Rifleman systems.

MSS and Rifleman Configurations

Standard MSS configurations use separate patrol, cold-weather and bivy components. The AKMAX Rifleman system takes a different approach: the GM and GT sleeping bags use bivy-cover-type waterproof shell material directly as the sleeping-bag outer fabric, so there is no separate bivy cover.

  • Rifleman Full Kit: GM sleeping bag + GT sleeping bag + black compression storage sack.
  • Rifleman GM: individual GM sleeping bag + compression sack made from bivy-cover-type material.
  • Rifleman GT: individual GT sleeping bag + compression sack made from bivy-cover-type material.

System and Component Procurement

Buyers may source a complete configured sleep system or individual components for replacement, samples, field evaluation and existing inventory programs. Project discussions may cover shell materials, insulation, color, labeling, compression sacks, packaging and production quantities.

Temperature performance, water resistance, supplied components and compatibility depend on the selected model and approved configuration. Confirm the intended climate, component list, test requirements, quantity and delivery schedule before quotation.
