Teton Sports scores big with the Mammoth +20° bag
Tank is still too restless for his own sleeping bag. But he will celebrate his 2nd birthday this summer, probably sleeping in the Teton Sports Mammoth double sleeping bag with his mom at a national park yet to be determined.
My two boys are getting old enough for big weekend camping adventures and that naturally leads to new gear purchases. Every parent cringes when they realize that shoes, clothes, or gear that worked like a charm a few months ago have been rendered functionally obsolescent due to a 3 inch growth spurt.
But the folks at Teton Sports have introduced a solution for the sleeping bag at least. The Mammoth 20° Double Sleeping Bag is a bruiser of a bag that measures 94″ x 62″ – big enough for my wife and two boys to snuggle in for a bedtime story or the 150th viewing of Toy Story.
We’ve been putting the Teton Sports Mammoth bag through the paces since I returned from the OR Show and it has been nothing short of amazing in camp and at home.

Ok. For those that love to camp like we do, the Mammoth is a great option for any camping trip. You can read the full specs on the Teton Sports Spotlight page. There are more images there as well.
The bag delivers what you would expect of a double bag. It’s roomy, takes up a sizeable footprint, and is a bear to get into the stuff sack by yourself.
But there are several elements of this bag that stood out for us in testing.
- Teton Sports knows loft – this bag, paired with 2 connected ComfortLite XXL pads delivers an incredible night’s sleep
- The full cotton flannel liner is softer and more comfortable than the synthetic liners used in most other bags
- The foot box is easily vented with the full length zipper – unzipped from the bottom up
- The shoulder baffles are key to trapping body heat inside – check out the video!
- The bag is two panels zipped together that can be easily separated – we used the bottom as a quilt
- The full length zippers are the easiest I’ve used – I can zip the bag from top to bottom and up again with a single hand
- A small adjustment on the hood drawstring creates an envelope for the pillows – stayed in place all night for the kids
The Teton Sports Mammoth 20° sleeping bag is a great option for camping trips with children. Of course, it’s a great way to bring a little romance into camp too for those long overdue couples retreats!
Kid tested, Parent approved
We tested the sleeping bag in Valley of Fire, one of Nevada’s most unique State Parks. We set up camp on Friday afternoon, unleashed the Mammoth, and hit the trails.
We returned to camp a few hours later and the kids made their first move on the tent. It was all giggles and screams (the good kind) for about 30 minutes as they bounced on the ComfortLite XXL pads topped with the lofty Mammoth. Bouncing a few times and then going airborn, they took turns bouncing on their butts. Good entertainment while we prepared dinner.
We wrapped up dinner with Smores and took positions around the camp fire. My oldest, not one to pass up time with the adults, asked if he could just go to bed in the sleeping bag. It wasn’t even 7pm yet!
Kids dig Mammoths
We took the three kids (my buddy and his daughter were camping with us) into the tent, got them snuggled in the bag, and started a movie for them. The three of us sat around the fire talking about what had just transpired. We talked for 45 minutes about it in fact. To the kids, it was probably the coolest fort ever.
For the next two hours, the kids nodded off at their own times as the adults sat just feet away next to the camp fire. Drinks, stories, adult conversation. The Mammoth helped us remember what that was like…way back before kids!
It’s not everyday that my kids gravitate to gear that way. Headlamps are more like toys than a sleeping bag. I get how appealing a good headlamp can be but I never would have guessed that a sleeping bag would be such a draw.
I asked Tater the next day what he thought of the bag. He said it was “way soft and super cushy”. There you have it.
Teton Sports delivers versatility in the Mammoth
One of the best characteristics of the Mammoth sleeping bag is that it can be connected to another bag. I’m not sure why you would need to do that but it’s designed to accommodate that.
The top and bottom panels can be completely separated by unzipping the two full length zippers along with the bottom zipper. This makes it viable as a quilt and cushioning for a summer outing or even as an underquilt for use with another sleep system.
It’s nearly the size of a queen bed which works well with many inflatable beds as well. We used the bag with our Alps Mountaineering pads in the Gear Lab this past weekend for a last minute guest. Not a bad option when all the guest rooms at Casa Miner were already spoken for.
The Mammoth would be a great option for campers, hunters, or anyone else that doesn’t have to focus on pack weight.
