I recently returned the North Star Jacket from Montane for this, the Chillwave and I could not be happier! When I buy a jacket I usually look for 4 things...
The Chillwave has exceeded my expectations in every single category. It is by far the warmest jacket I have ever owned. I will be spending time regularly in temperatures that average in the -20's (F) and I could not be more confident. Granted the Absolute Zero has it beat in the warmth category, but the Chillwave is just such a good deal. The Construction of this jacket is simply SUPERB and the fit is excellent. Im 5'11" 188lbs and a large fits me perfectly with ample room to layer appropriately! I love that the hood is removable, and that the pockets on this model are fleece lined.... in my last few jackets they were not and that, to me, makes a big difference.
All in all this is my first buy from Mountain Hardware, and I will be a customer for life. This is a fantastic parka!
