The Nest is designed as an underquilt for Hennessy hammock. Stop wrestling with pads inside the hammock. Stop waking up cold in the middle of the night. The “Nest” underquilt for Hennessy hammocks retains the convenience of the Hennessy bottom entrance with a split entrance w/non-snagging, mixed hook & loop (fastens to itself) that attaches to the Hennessy’s entrance hook and loop.
