Our Commitment

OUR PROMISE

Year-Round Comfort, Scientifically Guaranteed
SlumberPea’s temperature-regulating merino wool keeps your baby perfectly cozy from 55°F to 85°F (13°C-30°C). No more midnight checks for damp pajamas or thermostat adjustments – they’ll stay dry, safe, and just right through every season. Restful sleep for baby means peaceful nights for your entire family.

OUR MISSION

Born at 2 AM, Built for Your Peace of Mind
When engineer-mom Lena Carter swaddled her sleepless son in merino wool during a Colorado winter night, she proved nature outsmarts lab-made synthetics. Twelve years later, our mission remains unchanged: to end parental exhaustion with biology’s perfect sleep solution – one self-regulating sleep sack at a time.

OUR PASSION

Where Nature’s Genius Meets Human Ingenuity
We obsess over merino wool’s miracles:
→ Planet’s finest wool (18.5 microns, softer than cashmere)
→ 8000+ air pockets/sq inch for breathability no polyester can match
→ 30% moisture-to-warmth conversion – the original smart fabric
But we didn’t stop there: Our Grow-With-Me™ engineering means just two sizes fit 0-4 years – no more sizing guesswork.
