The Body Is the First Piece of Gear
Your body produces heat. It regulates temperature. It breathes. It senses moisture, daylight and cold — and it adapts.
Most outdoor equipment tries to seal all of that off from the weather. At Lucky Sheep® we take a different approach: gear should work with the body, not replace it. Wool that can take in water vapor and give back heat. Canvas that breathes. Shelter that lets air move through.
“It’s when you go outside that you especially need your body to work well.”

That is where every piece we make begins. Not with a spec sheet, but with what a warm, breathing, adapting body already does well.

- 4 lb / 1.8 kg
- Packs to 11 × 11 in
- US wool
- No synthetic insulation

Yes, it’s heavier than down. Here’s what the extra ounces buy.
| 20°F sleep system | The Rewilder (wool) | Typical down quilt | Typical synthetic bag |
|---|---|---|---|
| Weight | 4 lb / 1.8 kg | 1.3 – 1.5 lb | ~3 lb |
| Packed size | 11 × 11 in | volleyball | ~9 × 15 in |
| Warm when wet | Yes — keeps insulating damp | No | Partly |
| Breathability | High — no membranes or coatings | Low | Low |
| Noise | Silent | Crinkly nylon | Crinkly nylon |
| Plastic content | PFOS-free zipper only | Shell + often fill | All of it |
| Repairable & re-waxable | Yes | Rarely | No |
| Guarantee | Lifetime workmanship | Varies | Varies |
Down/synthetic figures are ranges from 2026 independent 20°F sleeping-bag tests (1.3–3.0 lb field). The Rewilder is about three times the weight of the lightest down quilts — and the only one on the table with nothing synthetic in it.

When things get real
Hands down the most comfortable sleeping bag I’ve ever used. In the backpacking world you typically have two options, down or synthetic. Now there’s wool — and it finally fits in a backpack. Your compromise is added weight, but every ounce is worth it when your sleep improves so dramatically. Climb in wet, wake up dry.Chris Holmes · The Rewilder
Lightweight enough for backpacking. If you have cold feet, they’ll warm up a lot faster than even lower-temperature-rated down bags. Absolutely one of the best investments I have ever made.Jason Stoher · The Rewilder
At 8,000 ft the temperature dropped below freezing and we got a powerful rain storm. Much of my clothing was wet. I was still able to stay warm and cozy even in the worst of conditions.Keven Anderson · The Rewilder
Real fibers for real performance
Wool, cotton and beeswax have kept people warm and dry for millennia. We just engineered them for a pack.
Warm when damp
Wool keeps insulating at 30 % moisture. Down doesn’t.
Breathes, never clammy
No membranes, no coatings. Vapour moves out; you stay dry.
Regulates temperature
Fewer 3 a.m. wake-ups sweating or shivering as the night shifts.
Natural fibers, zero PFAS
No synthetic fills or fabrics, no DWR, no foam. Nothing to off-gas in your face all night.
Built for decades
Repairable, re-waxable, and guaranteed for workmanship for life.

Patrick’s book grew from years of experimenting with how the human body, natural materials, sleep, weather and terrain interact — the same experiments that produced the first Lucky Sheep® prototypes. The book explores the philosophy. Lucky Sheep builds the equipment. The outdoors tests both.
