Sorry, I have no experience on these 2 jackets. But I do have preferences. Looking at these, I would not take the Mountain Man quarter zip because:
1. Fleece. It takes up too much room when packed.
2. It think it’s slightly heavier than the Compressor Classic. The Compressor Classic uses Primaloft. This is warmer, lighter, and stuffs smaller than fleece.
3. I personally, like full zip coats for easy on off w/o disturbing my great hair or stylish hat. <img src="/forums/images/graemlins/smile.gif" alt="" /> And it won’t pull up/off my undershirt when removing said coat.


The one uncertainty is breathability. If this is your number one most critical aspect, the fleece might work best. However, this needs to be tested.
