Engineered
at 68°F.
Nova Adapt is the world's first performance comforter designed to maintain the clinically proven optimal sleep temperature — all night, every night.

Your body heats up.
Your comforter makes it worse.
Traditional down traps heat. Synthetic fill clumps and creates hot spots. You wake at 2am, kick off the covers, then freeze. Repeat — every night.
The result: disrupted deep sleep, groggy mornings, and a comforter you've been settling for.
Nova Adapt doesn't just breathe.
It regulates.
The NovaTherm™ fill system uses phase-change microfibers that absorb excess body heat and release it the moment your temperature drops — keeping your microclimate at the optimal 65–68°F window, all night.
No flipping. No kicking off. Just sleep.
- ✓Active thermal regulation
- ✓Hypoallergenic — 100% animal-free
- ✓Machine washable at home
- ✓30% lighter than comparable down
The science behind the sleep.
Nova Adapt isn't stuffed. It's engineered.
Phase-Change Core
Microencapsulated phase-change material absorbs thermal energy at your body's peak heat output — then releases it as you cool. Active thermal management, passively delivered. No electronics, no batteries.
36-Direction Airflow
Our 300TC shell is woven with a hexagonal micro-channel pattern that directs airflow in 36 directions — eliminating the still-air pockets that create hot spots and trap heat against your body.
Weight-Optimized
Nova Adapt is 30% lighter than comparable down fills while maintaining equivalent insulation — reducing the pressure sensation that elevates core temperature during sleep.

Early testers. Real results.
250 beta units shipped. Here's what happened.
"I've tried every 'cooling' comforter on the market. Nova Adapt is the first one that actually works past midnight. I've stopped waking up at 2am entirely."
"My husband runs hot and I run cold. We'd been fighting over the thermostat for 6 years. One comforter. Problem solved."
"The weight is unreal. It feels like nothing is there — but I woke up at exactly the right temperature every morning for 3 weeks straight."
"The 65–68°F temperature window for sleep onset is one of the most well-established findings in sleep science. Products that actively maintain this range — rather than passively insulating — represent a genuine advance in sleep health."

Engineering the future of sleep.
"Sleep is the foundation of human performance. That’s why we created Sleep68. We discovered that traditional comforters were trapping heat and disrupting the body’s natural cooling cycle. The Nova Adapt was engineered to solve this—using phase-change material to lock your sleep environment at the clinically optimal 68°F. Welcome to the future of sleep."
