A Smoky Mountain drive-up weekend dropped into the low 30s last fall. Before I recommend any family double bag, I pull the live Amazon page and match specs to the ASIN.
Teton Mammoth Queen Size Double Sleeping Bag (ASIN B000F38YHI) is a Green Celsius Mammoth 0F queen-scale two-person rectangular bag with 94"L x 62"W dimensions, 16.5 lb weight, SuperLoft Elite hollow-fiber fill, 100% brushed poly flannel lining, and an included compression sack (July 2026 Amazon check).
Amazon maps this ASIN to 0°F temperature rating, 3 Seasons listing, dual zippers on each side, draft tubes, interior pocket, and water-resistant shell. Catalog price near ~$186.99 with 4.6 stars; Amazon shows Amazon's Choice.

Victoria Hayes's Verdict
Bottom Line
TETON Sports B000F38YHI fits drive-up families who want a proven queen double with flannel comfort and 94×62 in room, not trail ounces.
I'd treat 0°F as the rated floor and plan pad, tent, and dry layers for real comfort near freezing. Amazon also lists 3 Seasons, which matches how most car campers use this bag.
Pair it with how to choose a sleeping bag and our best sleeping bags review before you trust any all-family warmth sticker alone.
Best For
- Family car-camping trips where one bag covers two adults and a small kid.
- Base camp and hunting cabin overflow that stays near the vehicle.
- Couples on queen air mattresses who want shared warmth without zipping mummies together.
- Shoppers upgrading from budget doubles like our MEREZA double review.
Skip If
- You backpack miles where 16.5 lb fails your weight standard.
- You need independent warmth control on mismatched sleep temperatures.
- Your tent floor cannot fit 94 x 62 inches. See camping 101 choosing a tent.
- You want a sub-$60 budget double. Compare ShinHye flannel double instead.
Pros
- Verified Mammoth 0F Green ASIN. Amazon maps B000F38YHI to Celsius Mammoth 0F with Green color.
- Queen-scale footprint. 94 x 62 in exceeds typical queen mattress width for family spread-out sleep.
- SuperLoft Elite + flannel lining. Hollow-fiber fill and brushed poly flannel target cozy car-camp comfort.
- Dual side zippers. Two-way zippers on each side open for entry, exit, or blanket mode.
- Draft tubes and pocket. Zipper and shoulder draft tubes trap heat; interior pocket holds essentials.
- Compression sack included. Sized for 28 x 15.75 x 15.75 in packed bulk.
Cons
- 16.5 lb packed weight. Fine for SUV trunks; wrong for multi-day trail carries.
- Large packed volume. Bulky sack eats cargo space next to tents and coolers.
- 0°F vs 3-season reality. Real comfort still depends on pad and layers.
- Premium price tier. Catalog near ~$186.99 costs more than budget doubles under ~$60.
- Stuff-sack learning curve. TETON recommends stuffing from the bottom, not rolling.
- Shared warmth tradeoffs. One partner overheating while the other freezes is harder to fix in one double.

Victoria Hayes's Opinion
I'd load B000F38YHI for a North Georgia family weekend when we want one bag on a queen pad and the kids pile in before sunrise.
I've skipped it on walk-in sites where I'd rather carry two 3 lb mummies than wrestle 16.5 lb through the trees.
We verify listings before publish, not spreadsheet copy alone. I always confirm Green, Mammoth 0F, and B000F38YHI because TETON sells 20°F Mammoth variants on other ASINs.
Stack sleep gear using how to sleep comfortably while camping and car camping tips before you test any 0°F sticker at the forecast low.
Amazon Reviews
- Praise: roomy family fit, soft flannel feel, warm three-season car camps, durable zippers.
- Gripes: heavy to haul, tricky repack, runs warm on mild nights, premium price.
