I have asked Tim Marshall to make me one of his fine quilts. I have chosen the momentum fabric as the main material and I'm trying to finalize my choice for insulation. I want to be able to go down to at least the mid 20's and also be able to use the bag in the warmer weather. I live in east tennessee so we do get some warm days wiht higher humidity. I also plan on taking the quilt on some kayaking trips. I like the idea of synthetic for my needs and I need to pick either climashield combat or climashield xp. I've tried the search function, but I'm hoping someone else can put it all in plain english for me. I understand combat is warmer typically, but looking for some more imput from guys in the know. I know Tim won't steer me wrong, but I do want to make an informed decision.
Thanks in advance,
