i am about to purchase a hennessy hammock and i have been reading lots on these underquilts. i understand that it is wise getting one for my thru-hike in march and have no idea how to get one. are you supposed to make your own? and out of what? is there no where i can buy one?
i am at a loss and will no doubt have more questions as my planning goes on, but for now i could use some help with underquilts.
