Ok, been studying on making my own DIY UQ, the information here at HF is astounding as to the quality and quantity!
I am thinking of using a PL and be able to add or take away up two 2 layers of Climashield synthetic similar to the old adjustable layer CS Yeti.
So, I have the new PL and am getting ready to get the Climashield and found four different types at their website with 3 being shown for use with sleeping bags. http://www.climashield.com/outdoorourbrands
Seems like the Climashield-HL would have the best CLO and least weight, that is a guess on my part.
So does anyone know which of the 3, APEX, CL or HL, would work the best?
