Quick Overview

The Rothco Heavyweight Wool Blanket is a 62" x 80" passive thermal insulation asset used by operators, search and rescue personnel, and emergency preparedness-minded individuals to prevent hypothermia, provide ground insulation, and support casualty management in cold-weather field conditions.

The blanket's 55% wool and 45% synthetic blend delivers reliable thermal capability across multiple deployment scenarios. Wool fibers trap air and retain heat even when damp, making this blanket field-ready in conditions where synthetic-only alternatives fail. The synthetic content adds tensile strength and abrasion resistance, extending service life during hard use. Pico stitched edging along all four borders prevents fraying and provides more durable anchor points when the blanket is deployed as an expedient windbreak or shelter component.

Operators should understand the blanket's role within a layered thermal protection protocol. It is not a rated sleeping bag, and in extreme cold, high winds, or sustained precipitation, it must be integrated with a tarp, bivy, or insulating pad to provide adequate protection. In casualty management, the burrito wrap procedure traps heat the casualty is currently producing but does not actively rewarm the body. Moderate to severe hypothermia requires professional medical intervention, not insulation alone.

Sustained readiness requires disciplined sustainment. The blanket must be stored only when completely clean and dry to prevent mildew degradation. Deep cleaning requires cold-water hand washing with a wool-appropriate detergent, followed by flat drying in a shaded, ventilated area. Machine drying will permanently shrink and felt the material, rendering it non-mission-capable.

Field Application Steps

1. ASSESS THE THERMAL THREAT: Identify your primary heat-loss vector before deploying the blanket. Determine whether wind, cold ground contact, or ambient temperature is the dominant threat, as this determines your configuration priority.

2. UNFOLD AND ORIENT THE BLANKET: Fully unfold the blanket to its full 62" x 80" dimensions. For personal insulation in a standing or seated position, orient the blanket lengthwise across the shoulders.

3. EXECUTE THE MANTLE WRAP FOR PERSONAL INSULATION: Drape the blanket over your shoulders like a cloak, covering the back and sides. Pull the front edges together to cover the chest and neck, hanging the blanket as low as possible to retain body heat.

4. SEAL GAPS TO CREATE A RETAINED AIR POCKET: If seated, tuck the bottom edge of the blanket under your feet and legs to create a semi-enclosed air pocket. Cross your arms inside the blanket to concentrate heat at the core.

5. INSULATE A CASUALTY FROM GROUND CONTACT FIRST: Before wrapping a casualty, place a folded blanket or available insulating material beneath them. The ground is a primary source of conductive heat loss and must be addressed before overhead insulation is applied.

6. EXECUTE THE BURRITO WRAP ON THE CASUALTY: Place the blanket over the casualty and wrap securely, tucking it in along the sides and feet. Cover the head if no other headwear is available, keeping the face completely clear for airway access and breathing.

7. MONITOR THE CASUALTY CONTINUOUSLY: The burrito wrap is a passive insulation measure that retains the heat the casualty is currently producing. It is not active rewarming. Monitor vital signs and level of consciousness continuously and escalate to professional medical intervention if the casualty's condition does not stabilize.

8. SELECT A SITE FOR EXPEDIENT SHELTER DEPLOYMENT: Identify anchor points such as trees, rocks, or a vehicle positioned perpendicular to the wind direction. Site selection determines the effectiveness of the windbreak before a single edge is secured.

9. SECURE THE WINDWARD EDGE: Lay the blanket flat and secure the long windward edge using heavy rocks, logs, or cordage tied through the reinforced pico stitched edge. Do not use the main body fabric as the primary load-bearing anchor point.

10. RAISE AND SECURE THE LEEWARD EDGE: Raise the opposite edge and secure it to a higher anchor point such as a tree branch or the top of a vehicle tire. This creates a slanted wall that deflects wind up and over your position, reducing windchill exposure at ground level.
