TETON Sports Mammoth 0°F Double Sleeping Bag, Green, Queen Size 94 x 62 in, Poly-Flannel Lining

The TETON Sports Mammoth 0 Degree Double Sleeping Bag is a queen-size, double-person insulated bag designed to deliver roomy comfort and cold-weather performance for car camping, basecamp, and hunting trips.

Built to accommodate two adults or an adult and children, the Mammoth combines a plush poly-flannel liner, double-layer construction and draft-tube protection to keep heat close while offering space to stretch out. It unzips on both sides for flexible entry and pairs with a supplied stuff sack for transport. This description outlines its key features, common buyer questions, and who benefits most from the Mammoth.

How warm is the Mammoth for overnight camping?

The Mammoth is rated for cold-weather comfort and designed to retain warmth through dual-layer insulation and sealed zippers and draft tubes. While individual cold tolerance varies, the construction focuses on minimizing heat loss in chilly outdoor conditions when used with an insulating pad beneath.

• Dual-layer construction for added thermal efficiency
• Full-length shoulder and zipper draft tubes to reduce heat escape
• Mummy-style hood to trap warmth around the head
• Recommended use with an insulated camp pad for best results

Will it fit two people comfortably and still allow movement?

Yes—this bag measures approximately 94 x 62 inches (239 x 157 cm), larger than a standard queen mattress, giving two people room to sleep side-by-side or spread out. The extra width and soft lining make it suitable for couples, a parent and child, or anyone who prefers more space than a single sleeping bag provides.

• Queen-size footprint provides generous sleeping area
• Soft poly-flannel liner for next-to-skin comfort
• Zippers on both sides allow flexible entry and ventilation
• Roomy hood design for shared headspace without crowding

How easy is it to pack, clean, and maintain?

The Mammoth is designed for low-effort packing and campsite care. A durable stuff sack is included to simplify transport—just stuff from the bottom—and the bag’s outer materials can be spot-cleaned; follow the manufacturer’s instructions for full washing to protect loft and performance.

• Includes a large stuff sack for quick, compact packing
• Stuff-style compression avoids complex rolling techniques
• Spot-clean outer shell; follow label for full wash guidance
• Stow dry and ventilate between trips to preserve insulation

What features improve comfort for family and multi-use trips?

The Mammoth’s design balances warmth, comfort and family-friendly details so it works well for car camping, basecamp stays, and hunting camps. The soft liner, roomy dimensions and thoughtful draft control make shared sleeping practical while still providing individual zipper control for ventilation.

• Poly-flannel lining feels warm and soft against skin
• Dual zippers allow independent temperature control for each sleeper
• Mummy hood plus draft tubes keep cold air out of sleeping area
• Durable outer fabrics stand up to campsite wear and tear

Who is this for: The TETON Sports Mammoth 0 Degree Double Sleeping Bag is aimed at car campers, families, couples and hunters who want a spacious, warm sleeping system without buying two separate bags. It’s especially useful for anyone who prioritizes roomy comfort, easy packing with a stuff sack, and the ability to share a single bag on family outings or basecamp stays. If you need a compact ultralight bag for backpacking, consider a single-person model; for car-side comfort and shared warmth, the Mammoth is a practical, cozy choice.
