Comforters & Duvet Covers


The outer layer of the sleep system is the comforter with 37.5 technology. Insulation with 37.5 technology is encased in a 300 threadcount cotton with 37.5 technology blend cover to provide a perfect balance of comfort all night for a deeper, more restful sleep. We offer two weights of comforter for seasonality and personal preference.

Duvet Covers

A duvet cover can noticeably alter the breathable comfort of the duvet inside it. With this in mind, the system includes a duvet cover with 37.5 technology that won’t block the benefits of the blanket or down comforter while giving the bed a finished look. The duvet cover is made with premium cotton-blend yarn and 37.5 technology with a windowpane finish and has a hidden button closure and internal ties.
