I have ordered an IX Hammock Sock without SEEP, which should dispatch from MacEntyre around Dec. 1. I am quite certain it will perform well. Here is why.
On Nov. 13-14 Bomber and I went on an overnighter to a forest in the north of Sjælland. During the night the temperature dropped to 38F. In the morning I had no condensation what so ever in my setup, where as Bomber had lots of moisture on top of and in the down of his sleeping bag close to his head. I think the reason for this is that (on this occasion) the BBO raised the temperature inside the hammock to above the dew point.
On Nov. 26-27 I went alone on an overnighter to a favourite spot of mine. Forecasted temperatures for the night was 19F. Evening and late morning temperatures was 26F. It was a starry night with moon and no clouds. (Unfortunately I could not find the thermometer that night since it had fallen into the snow).
When I went to bed I took of my leather pants (which normally would be part of my sleep system) because they were wet at the bottom of the legs (I had not used gaiters).
Because of this I could not get warm in my feet so I took a space blanket and put it over my legs and sleeping bags up to my waist.
In the morning the outside of the foot end of the sleeping bag had some moisture on it just as one would expect. Apart from that all was dry.
On both outings my setup was the same and there was no wind.
Bet you the IX Hammock Sock without SEEP from MacEntyre will be awesome.
