A deep percale fitted sheet woven from 100% long-staple cotton in a genuine 300 thread count and pre-washed for a soft, relaxed handle from the first night. The percale weave stays cool and breathable, which suits warmer sleepers and warmer rooms. A 360 degree elastic grip runs around the sheet and it is cut to fit mattresses up to 36 cm deep, including those with a topper, and the cotton is OEKO-TEX certified.
