Linen

Linen is woven from fibers of the flax plant, which are naturally thicker and more irregular than cotton fibers. That irregularity creates small gaps in the weave that let air pass through easily, making linen one of the more breathable fabrics used in bedding.

Linen also absorbs and releases moisture quickly without feeling damp against the skin, and it tends to feel cooler to the touch than cotton because of its fiber structure. Many hot sleepers choose linen sheets specifically for summer, then switch to a heavier fabric in colder months since linen offers little insulation on its own.

The main trade-off, and a common surprise for first-time buyers, is texture: linen starts out noticeably crisp and even a bit stiff, and only softens after multiple washes. People expecting an immediately soft sheet sometimes mistake this break-in period for a low-quality product. Checking whether a listing describes the linen as stonewashed or pre-washed can set expectations correctly before buying.
