Patrol bag semi peapod
Depends on how big around YOU are, more than the hammock.
I modified a military MSS patrol bag with the gortex bivy cover to slip over the foot end of the hammock.
My 14 yr old son can get in it and zip it all the way up,
I can not say the same for me!
Picture is him hanging with it zipped up. He says it is toasty!
Wat I have done is sewn in a mostly full leangth pocket on the bottom of of the ENO doublenest to slide a pad in, and flipped the patrol bag UQ over to cover the top as a TQ and it worked fine for me in 19 degree temps this past winter.
