Is this sheet warm enough for winter?

Yes. The brushed flannel weave traps air and feels warmer than a plain cotton percale sheet, which is why it suits cold bedrooms. In a warm room or summer it can feel too heavy.

What does GOTS and Fairtrade certification mean here?

GOTS covers organic farming and processing standards along the textile chain, including limits on chemicals. Fairtrade certification means the cotton farmers received a guaranteed minimum price and a premium.

Will it shrink or pill?

Brushed cotton flannel can shrink and pill if washed hot or dried on high heat. Wash cold or warm on a gentle cycle and tumble low or line dry to keep the size and surface.

Does it come with a fitted sheet or pillowcases?

This is a flat top sheet on its own. Matching fitted sheets and pillowcases are sold separately if you want a full set.

How does it compare with polyester flannel sheets?

Cotton flannel breathes and wicks moisture better than polyester fleece, which can trap heat and sweat. Cotton is also less prone to static and tends to soften rather than mat over time.

How should I wash it?

Machine wash cold or warm with like colors and a mild detergent, avoid fabric softener, and dry on low. Skip bleach and high heat, which damage the brushed surface.
