My Background:  I have been backpacking for 2 years now and before that I car camped quite a bit. I consider myself somewhat new to backpacking and am on my way towards becoming a lightweight packer.  I tend to use a Hennessey Hammock since my only tent is a bivy tent.  I prefer the hammock to a tent as the hammock leaves me swinging gently in the breeze with no hard spot from rocks on the ground.  Nor do I need to dig troughs for my hips and shoulders (side sleeper) so I can practice LNT (Leave No Trace) much better.

Field Testing: This sleeping bag is going to show wear for a daily usage similar to a 6 month backpacking trip on the AT.  This sleeping bag is being used every night in my indoor hammock plus the times I get outside in the cold.  When I get up in the morning, the sleeping bag goes back into the compression sack to simulate being used on a hike. 

Temperatures so far have not gotten too cold although I did get outside one night at 15 F/-10 C.  The air was dry - no humidity or moisture.  The sky was beautifully clear which made it REALLY cold.  The altitude here is about 1675 ft/ 511 m.  I was in my Hennessy Hammock and had the SuperShelter attached.  I was dressed in sweats, wool socks and wore my Psolar Fleece Balaclava.  I stayed toasty warm with no chilled spots.  I left the foot box vented as I really like the extra room that I get with it open.

I have been outside in temps around 30 F/-1 C and the bag was very comfortable in my Hennessy Hammock even without the SuperShelter.  I tend to sleep warm and, so far, the sleeping bag has lived up to its rating.

I am hoping here REAL soon to get some experience in the bag in the snow.  It figures that where we normally have a ton of snow, this winter has been very mild.  This will change soon though as the lake has not frozen over so when we finally do get a cold front with snow, it'll hammer us.  I am looking forward to testing this in "true" winter conditions!

The zipper hitching that I reported on in my Initial Report has vanished with repeated use.  As a side sleeper I have found that I can sleep either on my side by pulling my sleeping bag around with me, or I can simply turn over on my side leaving the bag flat.  I have also used the sleeping bag as a "quilt" by leaving it unzipped, laying down, placing my feet inside the bag and pulling the bag, with the zipper on the bottom, up to my butt, leaving the "side" of the sleeping bag laying on top of me. The bag looks like this with a pillow showing where my head would be:

Sleeping bag as a quilt

One thing I have noticed with this sleeping bag, however, that I do not like is the hook and loop closure over the zipper by the hood of the bag.  I feel that it would be a whole lot better if the "grabby" part of the closure would be on the sleeping bag.  As you can see from the photo, the "hook" part of the strap has caught repeatedly on the bag when not in use, causing some fraying of the rim of the hood.  A simple "reversing" of the hook and loop materials will solve this problem.

Frayed bag

I have really enjoyed using the sleeping bag in my hammock inside.  I used to use my 35 F/2 C bag in my hammock but now I'm going to be putting that one away for when my grandsons come to spend the night as I have found that even when it's warm in my room, I stay comfortable with the vented foot box.  I'm in love with this bag!

Other than that, I'm very happy with the performance so far of this sleeping bag.

Things I like: The vented foot box, plenty of room for me to move around in.
