I am considering upgrading my Integral Designs, North Twin Model Primaloft insulated bag rated at 10F and weights 3.5 lbs. The hood only covers the bottom portion of my skull and it is not really warm enough. I think the temperature rating is optimistic at best and 3 lbs. 8 ozs. is not so light. The shell is Pertex, which is nice.
The above bag replaced a North Face Snowshoe 3D 0F rated bag which was warmer, but heavier, I lost in Chugach State park Unit 14C while relocating from one camp to another, just fell of the pack and was gone. Went into Anchorage and bought the above one.
The bag will primarily be used for Goat and Sheep hunting so it needs to be as light as possible. Temperature range from 0 - 20F. I usually sleep in long john base layers, socks, zip neck shirt and a thin hat.
This bag will likely last me the rest of my life, price is not a consideration, weight and warmth are. I think about 10F would be perfect, but it seems most are 0 or 20F. Thanks.
