For cyclists out there mashing away on multi-day rides, Rapha has designed a comfortable, lightweight sleep system. Their new Explore Down Sleeping Bag features high-loft 850-fill-power down with a DWR coating for moisture resistance and a temperature rating to 15º. Designed to work in tandem with their Explore Down jacket, the upper part of the bag is thinner, which saves weight and makes it much more compact for transport in your bike bag.
