next month i will be going on a week long canoe trek with my little brother and his boy scout troop. night time low maybe around 40 worst case. as of now i have a beat 10 degree bag, a fleece liner, and a thermarest self inflating mat thingy. this setup keeps me warm all winter camping around jersey and ny in a net but i am worried about the hammock. i dont want to pack to warm and bring to much stuff but i also dont want to be freezing all night. i was looking at getting a new bag for this trip (summer bag like 45 degrees) anyway because my other bag is so old and heavy.

i see everyone recommending the ccf pads, what about the thermarest air pad?

i will be camping in an nx-150 and i am 5'11" and 200 pounds so i am not skin and bones.
