A duvet of the highest standard: Sport Line is extra breathable, extra light, and extra warm. The Advance brand active microfibre filling is perfectly warm, airy, and light. The 100% cotton, superfine Mako plain weave, ergonomic long-stitching, and cotton piping all make the Sport Line one of the coziest duvets.
