I have just started an experiment adding a layer of IX to the out side of 1 layer of 2.5 oz/sq.yd Climashield WB torso UQ. In place of additional layers of CS. First impressions are very positive at 35F.
But now I am wondering if the VB effect will be enough to cause a problem. What do y'all think? I could start with the addition of a space blanket ( or even IX) cut out next to the hammock, then it should be even warmer and the VB effect of the IX would be moot.
