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.

    Perfect

    These sheets really do regulate your temperature. Initially, when you climb into bed, it’s a little chilly, but they warm up very quickly and are just the most perfect temperature. That is a very hot sleeper, these are a game changer. I also live in Colorado and our temperature is usually all over the place so it’s great to have a set that works for all year.
