Why we use Down
Down is a natural material, which provides unrivalled lightweight insulation. It provides warmth without weight in a wide range of temperatures. At Rapha, we use down in insulated garments for on- and off-bike use. All of our down comes from suppliers that meet the Responsible Down Standard.
How Down Degrades
The capacity to loft that enables down to insulate us against the cold. By trapping a layer of warm air against the body, the cold is kept out. But there are two key factors that can reduce this insulating effect: moisture and compression.
Water and perspiration can cause down to stick together and prevent it from trapping as much warm air. Similarly, whilst down garments are the perfect lightweight, packable layers for a bikepacking trip, prolonged compression can also damage the material’s ability to trap warm air. By all means, pack your jacket or gilet into a jersey pocket but try to keep it dry and make sure to unpack it at the end of your trip.
