I got I guess one of the first generation underblankets ? Delamere Mar-Apr 2007, I did try it the second night there, but I did'nt see much difference, remember this was my first night in a hammock also, first generation DD.
So its stayed in the gear room
since, however last outing to Morch's, I thought I'd try it again, first night, just my exped down mat, not fully inflated, and felt cold spots, usual, bum and heels, this was in a -5 deg C bag, I have a scrap piece of 6mm pad for sitting on, that ended up under my bum for added insulation.
NB The temp on one of my gadgets got down to 4.5 deg C however there was somewhere between 20-30 M/H winds blowing that night, even next day when it eased off it was still reading 17m/h
Second night, had a look at Tripitaka's set up during the day, and modified his approach to suit my set-up. I ran a second ridge line, under the tarp, and used this to tie up the underblanket, basically tied loops as close as possible to the u/blanket on the centre two, and slightly further away loops on the outer two, both ends, then used alpkit minicarbs to lock them to the ridge line, four sets of two bungee, four carbs. It worked a treat, no cold spots, and because the underblankets edges sit high on either side of you, so no wind felt either.
