Over it all is an 8x10 yard tarp. I'll be wearing some fleece and either a fleec or polarguard balaclava
I don't look forward to wrestling into the bag(s) inside the hammock. Any suggestions there?
Well any words of wisdom will be appreciated. Wish me luck....
are you out there yet in the cold? The way that BlackBishop described getting in the bag pretty well covers it. If for some reason I don't want to put the foot of the bag on the ground or on the pad on the ground, then I concentrate on keeping the hood of the sleeping bag all the way to the top of the hammock before I sit back in the hammock. I can accomplish this now, but it's never easy. I'm not sure how that will work with the big Agnes and Ridgerest pad. It might make it easier or harder. It sounds like you've got plenty of sleeping bags though, so your top insulation ought to keep you pretty well covered! You might indeed be able to get by using them quilt style which is both easier to get into and more comfortable. But if it's cold enough that you would need the hood on the bag, well in my experience, nothing quite equals that for keeping warm. So that would mean getting in there and using the bag as it was originally intended, rather than as a quilt. Or, possibly using a separate hood. There's nothing quite like a thick hood cinched down to a breathing hole if you are desperate to keep warm. As opposed to a bunch of warm air escaping around your shoulders and neck.
By all means use that space blanket over the Hennessy underpad. Although, with that Ridgerest inside a Super Shelter, I don't think you will have any trouble staying warm bottom insulation wise. If you weren't using the pad, other good tricks are placing light insulation clothing items on top of the pad, or heavier ones underneath the pad. Especially if you have any down clothing that you would otherwise be taking with you anyway on a hike. Or a trash bag lightly filled with either a space blanket or crinkled up newspaper (Garlington insulator) placed underneath the Hennessy pad. THE TRICK IS TO NOT have anything in there that's heavy enough to pull the undercover too far away from the underpad, leaving a big gap. Any gap is to be avoided.
Here is a trick I recently learned that seems to be helping with the pulling away problem. The elastic pull outs that come off of the side of the Hennessy hammock, through the loop of the underpad and out of the undercover to an attachment point: assuming that you have the elastics doubled or quadrupled for additional strength like Hennessy says for use with the undercover, I then take this elastics/guy out cord and bring it back over the top edge of the undercover and back out the exit hole in the undercover and through the hammock loop one more time. When I do this, the undercover tends to stay up in place much better than when I don't. Therefore, extra insulation that I place between the underpad and undercover don't seem to have as much tendency to pull the undercover down towards the ground. My experiments with it so far seem to indicate that it's at least somewhat helpful. But to whatever degree you can get that undercover to stay in place and not sag toward the ground, there's almost no limit to what you can put in there underneath the pad for many inches of extra insulation.
