Thinking about redoing my layering system this season. Looking at the kelvin active as a breathable mid layer in cold weather or an outer layer in warmer weather. I have used the FL uncompahgre for years in different layering situations and am familiar in how it performs, so looking for any insight on how the kelvin active jacket compares. Is it more or less breathable and is it warmer or colder than the FL?
