The technical difference between Takasa Warm + Luxurious sateen and Cool + Crisp percale is the way they are woven, and the functional difference is in the feel and warmth of the material. Watch video for a quick summary Percale has a weave of a traditional one-yarn-over and one-yarn-under grid, giving it a matte finish and a lightweight, breathable texture. High in durability, it gets more comfortable with every wash. The feel of percale is crisp and cool, making it ideal for warmer sleepers. Sateen sheets are woven using a one-yarn-under and three-yarn-over weave. This method exposes more thread surface and gives it a silky feel and sheen. The tighter weave on sateen gives it the feeling of satin (without the expense and fragile nature of satin). It’s also more heavyweight than percale, making it ideal for year-round comfort and warmth.
