A jacket insulated with natural down that will prevent heat loss during winter adventures. Put on the Diablo Down Jacket and you won't want to take it off again.The Diablo Down Jacket is a down jacket with an insulated collar. It will keep you comfortable on the trail in any conditions and guarantee adequate thermal comfort. The jacket is filled with 700-fill goose down, which is RDS-certified. This certification works to improve the quality of animal husbandry and the humane treatment of animals. This certification ensures that every stage of raw material sourcing has been carried out ethically and with due respect for waterfowl. The purpose of insulation is to retain body heat and prevent it from escaping. Down fill has a phenomenal warmth-to-weight ratio and is resistant to damage caused by compression. Therefore, it is widely considered the best insulation. The Diablo Down Jacket will provide you with thermal comfort without adding excessive weight.The outer layer of the jacket is made of nylon with FlashDry technology. The fabric's fibers wick moisture away, allowing it to evaporate quickly. The DWR (durable water repellent) coating repels water particles. This means you don't have to rush for rain gear when caught in a shower or snowfall. Elastic cuffs and an adjustable hem prevent heat loss. Wear the Diablo over a shell when relaxing or as a mid-layer when it's dry but cold.
