Body temperature-regulating SIJO CLIMA™ tech

SIJO CLIMA™ is our patented blend of fibers designed to absorb and distribute excess body heat as necessary—cooling you when you're hot, and warming you when you're cold. This material is also hypoallergenic, environmentally sustainable, and super luxe to the touch.

Supima Cotton (superior softness)

Supima cotton is made up of extra-long staple fibers that make it supremely soft and strong. A premium cotton grown stateside, Supima represents less than 1% of cotton in the world.

Moisture-wicking (sweat-free)

This particular blend of fibers makes the fabric moisture-wicking, meaning it'll absorb sweat quickly, keeping you cool and dry.

Oeko-Tex 100 certified

This snazzy certification indicates that our products and all of their materials are sustainably produced and proven non-hazardous and non-toxic.

    Great Duvet!

    It’s soft, light, and super easy to use (love the snaps!) a tried a lot of cheaper duvet covers but nothing could even compare- the money was definitely worth it for this one!
