Hi everyone. I hope this is the right section because of its relation to the thru hike of the AT I'm planning. I planning on leaving a little earlier in the season than normal. So I was wondering what everyones thoughts were on using a cold weather sleeping bag liner to add warmth to the 20* TQ/UQ setup I planning on buying. I'm hoping that as it warms up i can switch to different combinations of these along with venting for my sleep system. I'm thinking of using the Sea to Summit Thermolite Reactor Extreme Mummy Bag Liner. This is also my first venture into cold weather/thru hike hammoking.
