I am preparing to section-hike the Appalachian Trail, and because of the wet weather, I am thinking about using TQs and UQs with synthetic insulation. I understand that synthetics perform better under wet conditions, although with enough moisture their thermal capacity will also decrease.
I also understand that they are heavier and don't compress as much as down. I will be carrying a large pack, but am aiming at a maximum weight of 25-30 pounds. I think that the lack of compression won't be a problem, but I do have concerns about the additional weight.
Any advice? Other pros and cons of synthetics?
