We've just started making a couple of light KAQ underblankets for our Hennessy expeditions. Now, I see that on the group-buy Snugpak UB there are two additional shockcords in the middle of the UB. Searched the threads/photos but I can find no info on
1 if they are really necessary ( although I guess anything stopping air movement is good )
2 how they are fitted ? By which I mean are they attached to the outside shell of the UB, and thus compressing the insulation a touch, or are they fitted to the inside shell? Or are they sandwiched in the middle of of the insulation?
