Synthetic fill, not down

The name points to the cotton-feel lining, but the warmth comes from a synthetic hollow-fibre fill, not down. That is a genuine advantage in the British climate: synthetic keeps insulating when it picks up damp, dries faster, resists odour and goes through the machine wash without losing loft. Choose your fill weight by season, from the 950g version around +10°C up to the 1.82kg version rated to -15°C by the maker. Aim for the comfort end of that range rather than the coldest figure.

Built to last the season

The 210T ripstop outer carries a water-repellent treatment that handles ground moisture and morning dew, while the 210T Chunya polyester lining feels soft and breathes rather than sticking to your skin. Reinforced compartment seams stop the fill migrating to one side after a wash, so the warmth stays even trip after trip. The 210 x 75 cm cut unzips fully to lay flat, the hood drawcord seals in heat, and two bags zip together into a double. Pick Blue or Orange.
