So I'm having an e-mail thread with another HH SS user, and he says that Tom H. suggests using a parka underneath the OCF underpad in the HH Supershelter in very cold weather.
I've been pondering how best to use my Primaloft parka when hanging this winter:
- On top of my down bag as an overquilt
- Underneath the OCF pad as additional bottom insulation as Tom H. suggests
Of course the two uses will have very different impact. If used underneath, I'll need more top insulation (better sleeping bag or quilt), if I use it on top I'll need to find a way to get more protection for my backside (Thermarest, etc.) The question is really where it will be more effective and any tips to maximize that effectiveness. I need to pack my parka anyway to stay warm on breaks and at night in-camp, so I'm looking for the best way to incorporate it into my sleep system.
Searching back through the thread history it seems like using a parka or vest over the top is quite common.
Have any of you used a parka beneath you, either in a Supershelter or JRB Weathershield or maybe even a peapod? How well has it worked out?
I know Billybob is always a big fan of Garlington insulators underneath, and my parka is really just a Primaloft-filled Garlington.
For those using it as top insulation, how much of a problem is the down compression?
Yeah, I know YMMV and I'm going to have to try it out in the backyard here in Minnesnowta once the weather starts to chill down a bit, but wanting to get some helpful hints before my first excursion. Any guidance would be helpful.
