Built like a snow den. Soft like a cloud.

A snow den stays at the perfect sleeping temperature all winter because it is made of thousands of tiny air pockets. So is snösoft™.

Air-Cell Knit

A fine honeycomb of micro air pockets, knitted into the fabric itself. This is the structure other pajamas simply don't have.

Temperature Regulating

Holds gentle warmth when your baby runs cool and releases excess heat when they run warm. It works all night, in both directions.

Plant-Based Fibers

Breathable lyocell blended with soft cotton. No harsh bamboo-viscose chemistry, no polyester fleece, and none of that plastic feel.

Baby-Safe Certified

OEKO-TEX® Standard 100 tested fabric and snug-fit cuts made to U.S. children's sleepwear standards, from newborn sizes up.

The snösoft™ difference

Silky isn't the same as breathable.

Most "buttery soft" baby pajamas are flat bamboo viscose. It's a chemically processed knit that feels amazing in your hands and then traps heat against your baby's skin at 2am.

snösoft™ changes the shape of the fabric itself. Thousands of hexagonal micro air cells, the same six-sided geometry as a snowflake, hold warmth when it's needed and vent it when it's not.

The actual fabric, up close

You can see the technology.

Thousands of tiny hexagonal air cells, knitted into every inch of snösoft™: not sprayed on, not a coating, and impossible for a flat bamboo or fleece knit to copy. They hold gentle warmth when your baby runs cool and release heat and moisture when they run warm.

Our story

It started with a question about bears.

A newborn bear cub sleeps for months inside a den dug into snow, through blizzards and polar nights, and never overheats or freezes. Meanwhile, our babies couldn't make it to 2am in a heated nursery.

The answer wasn't fur. It was the den. Snow is millions of tiny air pockets that hold warmth and release excess heat, keeping the den at a near-constant sleeping temperature. We spent two years knitting that idea into fabric.

"Your little one already knows how to sleep like a bear cub. snösoft™ just gives them the den."
