When you clean your down jacket or bag, it does more than just get rid of the pong. Washing away dirt helps to restore warmth and breathability and - whilst you’re at it - you can treat your garment with reproofer to improve performance in damp conditions. Finally, tumble drying your down properly works out those clumps that form naturally when you get caught in the rain.
Washing your down can be intimidating, but it shouldn’t be! In fact, it’s quite easy to wash your down kit.
