USGI Patrol Sleeping Bag — Lightweight 30°F Modular Sleep System Bag. Standalone or System Component.
The USGI-style patrol/summer sleeping bag — lightweight, packable, rated for use down to around 30°F (-1°C). Run it solo for warm-season sleeping, or layer it inside the USGI Modular Sleep System for cold-weather temperature extension.
⚠️ Patrol Bag Only: This is the lightweight patrol bag as a standalone. No intermediate cold-weather bag, BiVy cover, or compression sack included. Pair with the matching components for the full MSS system.
• Lightweight Patrol Bag
Designed for warm-season and mild-weather sleeping — sized and weighted for fast field carry, not heavy expedition use.
• 30°F Comfort Rating
Comfort rated to around 30°F (-1°C) when used solo. Layer inside the cold-weather bag and BiVy cover to push the range much lower in cold/wet conditions.
• Modular Sleep System Compatible
Built to nest inside the USGI Modular Sleep System — runs as a standalone bag, or as the lightweight inner layer of the full 4-piece system.
• Olive Drab Field Color
Solid Olive Drab finish — classic military utility color that works with a wide range of tactical and field setups.
• Heavy-Duty Field Construction
Built from rugged nylon shell with insulated fill and a full-length zipper for ventilation control.
