I wore this jacket while hiking, above 10,000 feet in the Himalayas in late autumn/early winter. Minimum temperature was -5C.
I found it excellent while hiking as it's light, breathable and retains heat while damp. It's not suitable for camp as it's not warm enough when the body is at rest.
It could be made even better if it had simple non-zippered hand-warmer side pockets. It wouldn't add much to the weight (I assume) and would be useful for short breaks while hiking, when donning gloves would be overkill.

Bought as an active top, think I will get more use out it in the winter but so far I like it :)
Thumb holes to keep sleeves down/
