Why Soybean Fiber?

Soybean fiber is a plant-based innovation that combines the softness of down with the breathability of cotton.

It’s biodegradable, hypoallergenic, and naturally regulates temperature, absorbing excess moisture while keeping you comfortably warm.

Unlike synthetic fillers, soybean fiber maintains loft and freshness without clumping, offering a cleaner, more sustainable sleep experience for sensitive skin.

Comfy but wish it was a bit fluffier

For a plant-based fill it feels nice. Would’ve liked it a bit fluffier tho

Great for couples who sleep different temps

Got the autumn weight and it’s ideal for fall in Oregon. Cozy but not stuffy. My partner sleeps hot and even he’s obssessed with how it regulates temp.

So soft and breathable!

Honestly so impressed! I’ve owned down duvets for years, but this one feels just as luxerious without the heaviness or feathers poking out. Breathable and sooo soft!
