Your bed has never felt as good as it will once you put this duvet cover on it. Brooklinen's made this bad boy from a brushed twill made from long-staple cotton. Woven diagonally to maximize breathability, the fabric will only get softer with every wash — encouragement to wash your duvet cover more often. As an added bonus, if you use a duvet cover, you don't need a top sheet. You do need to supply your own duvet or comforter — besides that, this cover's got everything you need for a restorative night's sleep. Plus, all Brooklinen products are all OEKO-TEX certified chemical-free; your skin, and the environment, will thank you for that.
