Here's a look at my sleep system (including cpap machine).
The hammock is a Hennessey Deep Jungle XL. Between the bottom layers is the Hennessey Double Bubble radiant pad. It wraps nicely around both shoulders. In the bottom of the hammock, I have a folded over poncho liner with a Klymit Intertia X-Frame pad on top of that. The gaps let the poncho liner keep from compressing keeping me warm underneath down to 40 degrees. I haven't tried it any lower but I'm guessing it would go to the low 30's ok. I use a 40 degree summer bag as a top quilt and I have down slippers ready to go above my pillow if needed. The pillow is a Thermarest. I also have a sleeping bag liner (Sea To Summit - Reactor X-Treme) which I rarely use. I have 2 tarps. The stock Hennessey is for warmer nights and when the wind gets up, I use the Hennessey monsoon tarp with the blast doors on. Pitched in tight!!. It creates a little micro-climate and keeps me warm and dry when it's howling outside.
The CPAP is a Philips REMStar System One. In battery configuration, I don't run it with a humidifier. The battery is a BPS 160 Lithium Ion CPAP battery pack. It will give me 3 nights of 6-7 hour cpap use between charges. The CPAP weighs 3 lbs and it's bulky, but I need to use it. The battery is really light for what it does (1.6 lbs). As an upgrade, I'm looking to purchase a Transcend CPAP unit that weighs less than a pound and is about 1/3 the size of my current machine. I put the whole mess in a mesh bag and hang it from the ridgeline at the head end. The only downside so far is that on really cold nights, the air intake is out in the open and I'm sucking in freezing cold air. That could be fixed by bringing the machine under the topquilt with me.
Anyone else out there hanging with a CPAP machine? It doesn't have to keep you tethered home and unable to camp.
