Im camping this weekend, and want to try out the new hammock I made, can I use the max thermo inside with a Z rest underneath it?

then with a 20 degree bag, will I be warm at 30 degrees?

the insul mat is 2.5" thick.

I would usually sleep on the ground with 2 Z rests, and this 20 degree bag.
( and be warm enough)

never slept in a hammock, all this talk of being cold is scaring me!
