Minnesota Teen Braves the Cold for Over 1,000 Nights!
The story of Isaac Ortman, the 14-year-old boy from Duluth, Minnesota, who has spent more than 1,000 nights sleeping outside, is one of determination, adventure, and an unquenchable spirit of adventure. What started as a spur-of-the-moment challenge during a family cabin trip when he was just 11 years old has turned into a nightly routine that he doesn't see ending anytime soon.
After breaking his own personal record of sleeping outside for 10 consecutive nights, Isaac decided to continue his streak. He's been sleeping outside every night ever since and has accumulated more than 1,000 nights under the stars. His parents are supportive of his endeavor and have full faith in his ability to make the right decisions while sleeping outside alone in the dark.
A seasoned Boy Scout and camper and it's easy to see how his outdoor experiences have contributed to his love of sleeping under the stars.
The coldest night he's ever been was at -38°F. "I got a bit cold at the feet that night. I changed into warm stuff beforehand, but other than that, stayed pretty warm."
Andrew (Isaac's father) was confident that his son can survive that cold night. "I had confidence in him. He had already been out there for a long time and he had good gear and stuff like that. So I wasn't too worried."
Isaac was using the Sierra Madre Stratos Fly for his hammock camping (which he used for 600 nights before switching to the Nubé Shelter) and Inferno System 0°F along with other gear to keep him warm.
While most of Isaac's nights are spent in his own backyard, he occasionally branches out to more adventurous locations, such as the quinzhee or a family cabin about 30 miles from home. His parents have been supportive of his endeavors, even allowing him to sleep alone in the quinzhee on his special night.
Isaac's story is a testament to the joy and fulfillment that can be found in outdoor activities, and the determination to push oneself to new limits.

Engineered for maximum efficiency and warmth in the wild.
If you've ever had an underquilt slip out during the night, you know the chilling realization that follows! Inferno UnderQuilt stays in place thanks to its unique attachment system, allowing you to connect the points needed to keep it in place all night.
Use Case: Dependable Setup and Consistent Performance
Feature Call Out: Corner and Center Attachments
Generally, people have more mass on their top half, which is why Inferno UnderQuilt is shaped to fit to your body's mass. Notice the contour change about mid-way, this is how we optimize warmth and reduce weight.
Use Case: Space where you need it, warmth everywhere
Feature Call Out: Contoured Design
Ever notice how foot boxes just aren't designed for your feet? They're usually circles or squares (because that's easy to manufacture). Well we did something novel. We looked at how your feet rest and designed the foot box around that - genius.
Use Case: Warm, Non Claustrophobic Feet
Feature Call Out: Spacious Trapezoidal Foot Box
We crafted Inferno UnderQuilt to work with our Ninox FlatLay Hammock, this hammock has an incredibly aggressive diagonal lay. Thanks to our Snug Strips you won't feel the pressure of the diagonal lay and that seal helps conform the insulation to match your body and keep drafts out.
Use Case: Laying diagonally in a hammock.
Feature Call Out: Snug Strips wrap around you, bringing insulation close.
Being in the wild has its own set of challenges, make sure being warm isn't one of them.
The Inferno Insulation System is designed to provide 'head to toe' warmth in the face of uncertainty. Rest easy knowing the Inferno's comfort ratings will stick with you even when the unexpected happens.
I bought the top quilt for my winter start of my AT thru hike, had it sent back from home when I reached Vermont. This sleeping bag did not disappoint!! It got down in the singles a few nights, and I was PLENTY warm, and very durable! The hood with the cinch cord to cover your face really comes in handy too. Worth every penny.
It did have a funny smell when it arrived but it aired out fairly quickly.

I truly love the Inferno system; especially how the top quilt basically fits around you. I have both the 30 and 0 degree set and have not been disappointed. Highly recommend this system!

I figured I’d put this to the test with my Dad. I took him on his first ever hammock overnighter and to be honest I was a little nervous. It was his 65th birthday weekend and I wanted to make sure the old guy slept well and was warm. Dad had the Pares hammock with Puffle 40’ and the inferno underquilt. Granted we are in Florida but it did drop down to 55’f overnight. At one point he was snoring like a bull gator and woke up refreshed. His first words, “wow I slept cozy.” We had a cool fog roll in with a little moisture and dew so the Puffle and inferno both got damp. But the dew just rolls off and drys out in time to pack up. Inferno for the win - giving the birthday guy a great night sleep so he wasn’t grouchy for kayaking the next day. Confession though: I was thinking I wouldn’t keep the inferno since I’m in Florida but I really am jealous of his good nights sleep. I think I’m going to have to keep it now.

I don’t fit anything built for the outdoors as I’m 5’7” 280lbs shoulders and chest. Figured at least with an open back design like this it might work. I needn’t have worried as the top is spacious and toasty. First trip out got caught in a thunderstorm strong enough to rip off my rain fly and drench my whole system. The duck down worked perfectly keeping me warm in spite of being wet and quickly dried from my body heat. I love what you’ve made and hope you keep it up!
