If you are looking for a new down jacket which you can use during your hiking, backpacking or any other backcountry adventure mainly during spring and autumn or as a mid-layer during winter then the Rab Microlight Alpine Jacket could be an option and here comes a short review. I was hiking with this jacket in -5 °C and felt comfortably warm just wearing a t-shirt under it. However, I started to feel cold at this temperature when I was not moving.
Since the jacket is filled with down it takes much less space in your backpack than a synthetic jacket. Alternatively, you may also have a look at the Montbell UL Down Parka which is a bit lighter than the Rab Microlight Alpine jacket and which is my current down jacket.
The Rab Microlight Alpine Jacket weights 345 grams is filled with 140 grams of 750 cuin goose down.
The Rab Microlight Alpine Jacket is a nice down jacket which is also quite affordable. If you look for a real winter down jacket then the Rab Positron Jacket might be an alternative (at least I would pick it as my winter down jacket). However, if you are looking for a jacket which you can wear in the evenings in the camp or as a midlayer during the winter then the Rab Microlight Alpine Jacket is a great choice. Here you can find a list of my favorite down jackets.
