High Peak Sirius
There seams to be some confusion with the High Peak…
Temperature Rating: I would say 40 degrees
Weight: 13.44 oz
Price Paid: $40
There seams to be some confusion with the High Peak temp ratings. I was told that this was rated at 21 degrees. Well...it is. That is the temp you will die of hypothermia.
As I was looking for a warm weather bag of +40 degrees and needed a light weight bag for summer use, I knew that there is no sleeping bag on the market that only weighs 13.44 oz that could be a 21 degree bag. Looking though the specs I soon realized that its true rating was 52 degrees. This is the temp that one will be very comfortable. At 45 you will shiver and be chilled.
I have used this bag on all my summer backpacking trips. I have had no discomfort at all down to 42 degrees. Now this doesn't include the warmth that the tent holds in.
This bag is a well built mummy bag that I draw tightly around me. It seems to have a little more insulation around the head and foot areas. This is important as the head loses more heat than any other area of the body. And keeping my feet warm is very important for me. It has a dual zipper on at the head and the foot of the bag, and has a pocket that is on the inside of it. It packs down to the size of a football. And like I said, very light weight. For my needs and wants, it is the perfect bag.
PS; I'm not going to try to test it down to 21 degrees.
