I think I might just give Aron a call and cruise over there to check one out. I guess my only issue with the Slick is the insulation fill material "climashield" is the same stuff in my North Face bag and that thing sucked! My nuts were the size of raisins in that thing at 34*. By far the worst bag I've ever owned. I think the materials used in the Slick are superior but the fill is my one and only real question on it I guess.
I believe that Kifaru uses a military spec which is different then what most companies like NF use but check with Aron, I could be wrong.
