All of my camping is wilderness, usually on 1-2 week long hikes, this makes weight and durability important. My Ultamid2 outer accomplishes this.
For the inner, my priority is weight with reasonable durability.
Realizing that multipurpose use necessitates compromise, I need to accommodate 2 types of weather:
1. Shoulder Season - Very wet, moderate wind,with temps ranging from 10C(50F) to -5C(20F).
2. Winter - Dry, moderate wind, with temps ranging from -10C(14F) to -30C(-22F).
70% of my campsites are in the woods, only occasionally having to camp on an exposed land above the tree line or in a river valley.
My very cold winter camping experience is limited, and to date have used the cuben mid pitched about 6" off the ground with a cuben\event bivy inside. I have done this down to -24C. I want to move to a more comfortable space with a floor as the ground I camp on is often wet which adds much condensation in the shoulder seasons, and I want the same inner to be adaptable for optimum very cold winter conditions.
So far I assume I would use a breathable material (Momentum, Pertex?) for the solid panels and the lighest noseeum for the mesh panels.
I am thinking of the following starting from the floor and moving up:
- solid panels up 12-18" from floor
- then mesh 6-12" horizontal panel
- then 2nd solid panel above that
- then a second mesh panel to the top peak, with the lower mesh panel having closable flaps for really cold nights.
The outer cuben tent has 2 top mesh vents that can be closed with flaps. If they were closed and the outer tent staked tight to the ground, I am thinking the upper mesh panels could be left open with minimal airflow and no spindrift.
I also use a Uco Candle lantern during the winter, not for warmth but to increase air movement through the tent. I would hang it fro the peak about 2 feet down, level with the upper solid panel which would push air up and theoretically draw air in through the lower mesh panels.
I am left with 2 questions:
1. Would there be a situation where I would want to completely seal the inner with no mesh at all?
2. Would the closable lower mesh panels be sufficient on 2 sides only, to save weight.
