SIERRA DESIGNS BLACK POLARGUARD 3D SLEEPING BAG USED

Add a proven cold-weather sleeper to your surplus and outdoor lineup with the Sierra Designs Black Polarguard 3D Sleeping Bag. Originally issued through military and government contract channels, this mummy-style bag brings the trusted Sierra Designs build and Polarguard 3D continuous-filament synthetic insulation to campers, hunters, preppers, and field operators who need reliable warmth in damp, cold, and unpredictable conditions. This is authentic issued gear — real provenance, real field pedigree — not a modern remake.

Why This Bag Sells

Polarguard 3D was the go-to synthetic fill for serious backcountry and military sleep systems for years, prized because it keeps insulating even when wet — a critical advantage over down for hunters glassing wet ridgelines, hikers caught in shoulder-season rain, and preppers building a bug-out kit. Sierra Designs paired that fill with a proven mummy cut that traps body heat around the core and feet while cinching down at the hood to seal in warmth. The result is a bag that end customers immediately recognize as a serious piece of kit.

Construction & Features

• Insulation: Polarguard 3D continuous-filament synthetic fill — retains loft and warmth even in damp conditions.
• Cut: Mummy profile with contoured hood for efficient heat retention and reduced dead air space.
• Shell: Durable black synthetic ripstop-style outer with a light-colored interior lining for visibility and comfort against skin.
• Closure: Full-length side zipper with draft coverage for step-in access and ventilation control.
• Hood: Drawcord-adjustable hood collar to seal in warmth on cold nights.
• Build: Baffled quilted construction to keep fill evenly distributed and prevent cold spots.

Condition — Genuine Used Surplus

This is used, previously-issued surplus. Expect honest field-use character: minor scuffs, faded markings, and the patina you'd expect from gear that has already served in the field. That authenticity is exactly what collectors, reenactors, and value-driven outdoorsmen are hunting for — a genuine Sierra Designs Polarguard 3D bag at a working-gear price point, not a copy.

Who It's For

• Hunters and anglers needing a synthetic bag that shrugs off condensation and damp tents.
• Backpackers, thru-hikers, and campers building out a three-season sleep system.
• Preppers and bug-out-bag builders who want proven insulation at a surplus price.
• Airsoft and milsim players running overnight ops.
• Scout troops, cadet programs, and outfitters equipping loaner gear kits.
• Military surplus collectors seeking authentic Sierra Designs contract sleep gear.

A strong, quick-turning stock item for any outdoor, surplus, or tactical retailer whose customers care more about how gear performs at 3 a.m. in the rain than how it looks on a showroom floor.
