Each mummy sleeping bag combines a contoured shape, draft protection and compressible insulation to help balance warmth, weight and packed size.
Precision quilting, verified fill weights, and scalable B2B production for your sleeping bag collections.
A mummy sleeping bag is a thermally efficient field sleep system engineered with a contoured hood, tapered torso, and anatomical footbox that closely follows the human body. Compared to standard rectangular bags, the mummy profile maximizes warmth-to-weight ratio and minimizes packed volume—making it the standard choice for military field ops, alpine trekking, and cold-weather camping.
Zennison manufactures mummy sleeping bags across full seasonal and tactical ranges—from compact tropical jungle bags and 3-season synthetic models to 800-fill-power alpine down bags and multi-layer military sleep systems (MSS). Buyers can select from our proven baffle patterns or customize dimensions, shell fabrics, insulation types, zipper configurations, and branding to match target market requirements.

We build mummy sleeping bags and modular sleep systems around the insulation, shell fabrics and packing requirements of your defense tender. Options include durable ripstop nylon, synthetic micro-fills and waterproof bivy covers. Olive, coyote and camouflage colorways can be matched to the project specification.
Technical outdoor brands need mummy sleeping bags that balance warmth, weight and packed volume. Options include calendered 15D/20D down-proof fabrics, box-wall baffles and high-fill-power duck or goose down. We help develop target temperature tiers such as -15°C, -5°C and +5°C, with EN/ISO rating support for the selected models.
Our 3-season hollow-fiber mummy sleeping bags combine soft pongee linings with anti-snag zippers for retail camping ranges. Specify left/right zipper pairing, custom color blocking and private-label packaging to suit your collection. Machine-washable models can be specified according to the selected shell and fill.
Wider torso options give hunters room for layered clothing during nights in wall tents or under tarps. Our hunting mummy sleeping bags offer water-repellent shells and camouflage patterns for late-season catalogs. Quiet shell fabrics and mud-resistant foot liners can be specified around the intended use.
Synthetic mummy sleeping bags offer compact packing for relief kits and preparedness stock. We support NGOs, civil defense agencies and emergency kit suppliers with fill weights, packaging and production schedules matched to project requirements.

Consistent insulation weight and suitable shell fabrics help each mummy sleeping bag deliver its intended warmth. We check down-proofness and DWR water repellency before cutting. Automated pneumatic scales control fill weights within a ±5 g tolerance per chamber. Each finished bag passes through a conveyor needle detector before packing to check for metal contamination.
Quilting and baffle construction help keep insulation evenly distributed throughout a mummy sleeping bag. We use computerized multi-needle quilting and offset double-layer construction to reduce cold spots along stitch lines. Each insulation batch is logged with the relevant loft or fill-power records and cleanliness reports for procurement reviews and brand audits.
Packed volume affects landed cost when ordering mummy sleeping bags in bulk. Controlled mechanical compression packing for synthetic models can reduce shipping CBM by up to 40% while preserving loft recovery. We can schedule split shipments across temperature ratings and colorways to match your warehouse intake.
Every mummy sleeping bag order begins with a physical pre-production sample to lock in shell fabric, insulation GSM, baffle structure, and zipper smooth operation. We only start bulk cutting after your team approves the sample's loft recovery and compressed stuff-sack size.
Beyond sleeping bags, Zennison manufactures sleeping pads, camping cots, waterproof bivy covers, and camp pillows under the same roof. We match fabric colors and branding across categories so you can launch high-margin bundled sleep kits in a single consolidated shipment.
Seasonal restocks require identical thermal performance and color accuracy. We archive your approved mummy sleeping bag patterns, fabric dye-lot swatches, and chamber-by-chamber fill weights so your repeat orders match your first shipment down to the gram.

"We worked with Zennison to develop our -10°C alpine mummy bag line. Every production batch matched our required GSM fill weight and passed third-party ISO 23537 thermal testing on the first run. Zero down leakage issues."
"For a defense logistics tender, we needed 12,000 modular mummy sleeping bags with custom waterproof bivy covers. Zennison delivered on a tight 30-day schedule, and their vacuum-compressed packing saved us two full 40HQ containers in ocean freight."
"We started with 500 hollow-fiber 3-season bags to test our retail market. Zennison handled our custom color blocking, Left/Right zip pairing, and French/English temperature charts seamlessly. Reordering for spring season took just one email."
Choose RDS duck or goose down (600FP–850FP) for premium backpacking and mountaineering lines: it offers the highest warmth-to-weight ratio, smallest compressed pack size, and longest lifespan. Choose synthetic hollow fiber or micro-fill for military tenders, wet-weather camping, and budget-friendly retail lines: it retains warmth even when damp, dries quickly, is easy to wash, and keeps unit costs much lower. Tell us your target retail price and climate, and we will recommend the exact fill spec.
Temperature ratings depend on insulation type, fill weight (GSM), baffle construction, and shell breathability. During project evaluation, our engineers recommend proven GSM formulas based on ISO 23537 / EN 13537 test data (for example, 250g/m² hollow fiber for +5°C/0°C 3-season use, or 500g/m² double-layer fill for -10°C/-20°C winter use). If your retail or tender program requires official lab certification, we coordinate third-party thermal manikin testing.
Yes. Using matching two-way separating zippers, a Left-zip and a Right-zip mummy bag can be zipped together into a double sleeping bag—a popular feature for camping brands. You can split our standard 500-piece MOQ evenly between Left-zip and Right-zip configurations (e.g., 250 Left + 250 Right) at no extra cost.
Each sleeping bag is packed into its own oxford compression sack or drawstring carry bag, placed in a polybag with barcodes, and loaded into master cartons. For synthetic fiber bags, we offer controlled compression packing that reduces carton volume by 30%–40% to maximize 20GP/40HQ container quantities. For high-loft down bags, we use semi-compressed packing so the down feathers recover full loft immediately upon unpacking.
Wash in cold water on a gentle cycle in a front-loading washer using mild soap or down-specific cleaner (never use fabric softeners or bleach, and never dry-clean down). Tumble dry on low heat with clean tennis balls to break up clumps and restore loft. For long-term storage between trips, store the bag uncompressed in a breathable mesh sack rather than tightly strapped in its compression sack.
