Tencel™ Lyocell is a fibre derived from sustainably sourced wood pulp. It is known for its soft feel, high breathability, and durability—not to mention its moisture-wicking properties. So, you can rest assured that your Casper Down-Alt Duvet will keep you cool and comfortable for many nights to come.

Yes, this down alternative duvet is made of just two materials—TENCEL™ Lyocell and recycled polyester—both of which are hypoallergenic.

Yes! This down alternative duvet is warm and cozy but also very breathable, thanks to the TENCEL™ Lyocell cover. This makes it suitable for all seasons.

The main difference between down vs. down alternative duvets is the filling. Down duvets are made with filling sourced from the undercoat of birds, while down alternative duvets use filling that is made from a synthetic fibre (often polyester) that mimics the softness of traditional down. Down alternative duvets are a hypoallergenic option that may also be more ethical and sustainable than traditional down duvets.

To wash your Casper duvet, machine wash it on a cold, gentle cycle. Do not bleach. Tumble dry on low heat with clean tennis balls to help maintain its loft, and remove it promptly once dry. Do not iron or dry clean the duvet.
