Base your choice of down jacket on the main activity you want to use it for. How warm and compressible do you want it to be?
Consider whether you need a jacket filled with water repellent down – one which will take longer to absorb:
Your moisture as you perspire
Water when you get caught in light rain.
Also take into account the construction and fit of the jacket you want to buy and how you want to layer it – as a midlayer under your rain shell or as an outer layer over your thermals.
At Kathmandu, we label each of our down jackets on a ‘warm’, ‘warmer’ or ‘warmest’ scale along with weight and packability levels – so you can make a well-informed choice on which down jacket is best for you.
