Most duvet covers feel wonderful in the shop and ordinary by the second wash, because the softness you paid for was a finish applied at the end, and it goes down the drain the first time you clean it.This one gets its hand from the cloth. The yarn is spun fine and even, without the short ends that make cheaper cotton pill and go rough, and the sateen weave floats it across the surface, which is what gives the cover its low sheen and its heavy drape. That is structural, so it survives every wash and keeps softening instead of thinning.Both faces are the same fabric. Most covers put a presentable weave on top and something cheaper underneath, which means the side against your skin all night is the side the label never mentions. The count is 300, which sits near the top of what a square inch of cotton will physically hold. The color is the cotton's own rather than a dye bath, so it reads natural rather than bleached white.It closes with a zipper along one side. Cut and sewn in New Jersey, sized to fit our duvets and standard comforters in the same size range. The sateen carries Global Organic Textile Standard (GOTS) certification under license GOTS-10229, issued by Oregon Tilth, and the license is public so you can check it yourself.
