CF,

Temps for my use with the bag I'm looking for have ranged from
50 degrees at night down to 15 thus far. Of coarse I can unzip on warmer nights.

So far I've ran 25 degree and 20 degree bags in this range and only slightly been chilled on very few occasions. But those nights I went to bed with nice warm meals in my belly and a dry/light under layer on..


I'm thinking that some warmth will be added with the use of a bivy. Which would get me to 15 deg with comfort using a good 25 deg bag. I also usually carry a sea to summit liner that has a 9 degree rating. So 10 degrees with bivy and liner I feel is will have plenty of comfort for me. Now if I go with a 20 deg bag I hope 5 degrees is at a comfort level. But if'n things chang with a quickness and I get wet or damp that changes alot.

So maybe a 10-15 degree bag makes more scence..

I'm leanning towards Kifarus Slick bag but there just isn't alot out there as far as reveiws..

Their 20 deg bag weights 2.2 pounds and their zero weights 3.3 I believe..

Many out there will claim that with synthetics I just can't get warm and light in the same package.

Another reason I appreciate help/advice and suggestions from you folks..
