Ive got one of those cocoons, unfortunately i have hennesy hammocks so they are not suitable unless i remove the net and subsequent high ridge line.
i saw Bodges at a meet and he looked well toastie, if i cant find a cheap hammock i might consider cannibalizing on of my hennesy's so i can give it a go.
the underblankets and quilts from ian are great, so i am sure the cocoon will be.
