An alpaca duvet is the sort of present that is unwrapped once and used every night for years. My Alpaca's All Seasons duvet is filled with pure alpaca wool and sewn into a casing of densely woven cotton, made to order by the quilters of Krosno, in south-east Poland, so the filling stays exactly where it was laid.

The name is the point. Alpacas live high in the Andes, through frost by night and fierce sun by day, and their fleece has developed to cope with both. The fibre helps regulate temperature as the body warms and cools through the night, takes up moisture and lets it go again, and keeps the duvet dry, breathable and soft. It contains no lanolin, and My Alpaca adds no chemicals to the filling, which makes it kind to sensitive skin.

One duvet for every month of the year, and a persuasive argument for an early night.
