I have a set of the 2012 stuff (I think) and really like it for hunts where weight is less of a concern, I.e ATV or boat based trips, or packraft trips where the hike in is on the shorter side. I would guess I have around 50 days in mine, and I have always stayed warm and dry in my Koldo set. while not "breathable", the pit zips work well enough for ventilation when on the move. The interior fabric is much less clammy than the Helly Hanson Impertech I used here in AK previously for similar trips. Kryptek is one of the few mainstream lines that offers small enough sizing to accomodate those of us who are of smaller stature (I have a men's small size and its roomy, but fits me well at 5'3) and I like that it's cut generously enough that I can actually layer a puffy coat underneath the jacket if I want to.
I use lighter weight eVent jacket and pants for backpack trips and hunts, but if you don't mind the heavier weight the Koldo is good gear.
