Yes. It makes for a very comfortable night's sleep if you have the patience for getting it in place properly while settling in for the night, especially with the chair kit since it helps flatten the back profile.
The 7 regular on top of a 3/4 Ridgerest works well for me down below freezing, but you can encounter some cold spots where you elbows and shoulders come hang off the side and come in contact with the uninsulated bear pinata. Just lay a jacket or extra clothes along the side and forget about it.
The 9DLX in the HH is, well...deluxe hammock accomodations with the only problem being getting out of the thing. The extra width makes for a super comfortable night's sleep.
