i got a down big agness 20 degree bag which allows a thermarest neoair pad to slip in like a bb double layer which is the hanger i use of course. it slides in the bags underslot so it does not shift when i move. saved me a bundle not buying uq or tq because i had these items when i slept on the ground.
I hate sleeping bags. I could sleep in a coffin rack on a destroyer for years without issue, but put me in a sleeping bag and I'm claustrophobic. If you have a SB but want the openness and weight savings of a quilt just cut all of the extras out of the SB that you don't use when it's being used as a quilt. I took a junky Lafuma 1000 Extreme that I picked up at REI's scratch and dent sale for $20 and started cutting out all the useless shock cord, that strip of material that seals around your shoulders, tags, and the zippers. I took from 2lbs 9 oz down to an even 2lbs. Now 2lbs is still more than a competitive down quilt, but it got me thinking that with SB's being relatively cheaper and easier to come by, that I may just look for a SB that fits my needs and cut the grams out of that one too.
My initial experience with a hammock was using a bag. I was a total idiot and froze my butt in a 40*F rated bag that was always warm into the upper 30*F on the ground during my +50*F night. Broke out the pads and struggled getting into the bag and keeping the pads from wrinkling, sliding...(HH days). Found hammockfroums.net!!! Eureka the underquilt concept. The Nest arrived. Warm butt. Started using the bag like a quilt. Liked it quilt style more than bag style. Then quilt acquisition syndrome kicked in.
Nothing wrong with a bag vs. quilt. Whatever you prefer.
My first night out on the trail as a hammocker, I crawled inside my bag and then squirmed inside my HH. With a ccf pad under me, I stayed warm. However, in the middle of the night, when I was dead asleep, I had a wicked bad claustrophia attack. I broke out in a sweat trying to free myself. I love my bag but never again will I crawl inside it to sleep - it works much better for me as a quilt.

I've had my exped wallcreeper 650 for about a month now and have been using it quite a bit for my naps in the house and on cooler nites out on my porch. it's a top center zip and much easier to get into than a side zip. I also use a piece of shock cord at the head and foot tied to the ends of the hammock (bb) to keep the bag stretched out when getting into it. while I take a nap I use it in top quilt mode leaving it a bit zipped up at the bottom to create a foot box . I've got down to 41.9 degrees last night for my record low. I'd try out lower temps but it just doesn't get that cold here .....
Where did you attach the shock cord on the bag? I have a EXPED too, and was thinking along the same lines....
