Is this blanket warm enough for winter?

It is a lightweight down blanket, so most people use it as a summer layer or under another comforter in winter. In a cold bedroom it will likely feel thin on its own.

Does it need a duvet cover?

A cover is not required, but it protects the cotton shell and keeps the down cleaner. It also makes washing far easier, since down blankets should be cleaned infrequently.

Can I machine wash it?

Down blankets can usually be washed in a front-loading machine on a gentle cycle and dried low with dryer balls, but check the care label first. Spot cleaning and airing are safer for the fill.

What sizes does it come in?

It is offered in Twin and Twin XL only. There is no Full, Queen or King version, so larger beds need a different blanket.

Is it good for people with allergies?

The OEKO-TEX certification covers testing for harmful substances in the fabric, not down allergens. People with a down allergy should choose a synthetic alternative.
