The Subkilo is nowhere near the WM in warmth. It is sewn-through, and I put it around a 32 degree bag, well above its 20 degree rating.


I recommend the Montbell UL SuperStretch Down Hugger series. I have a #3 (24 degree) and a #5 (40 degrees). They have plenty of room in them, are lightweight, have a great hood, and are spot-on their ratings.
