Hammock can be good, but you definitely need an under-quilt at elevation or colder seasons. Dropping the hammock closer to the ground, adding a rainfly, and using an under-quilt makes it doable, but not always comfortable.
For the hammock method, thermal blanket (although usually noisy) can retain heat, and Hot Hands style thermal packs can add needed warmth....last all night.
However, for ~2lbs more, one can use the military Improved Combat Shelter (ICS) with fly, poles, et el. Fully contained enclosure with waterproof floor (dry in torrential rain as long as drainage to prevent pooling greater than floor turnup depth), ventilation netting, rain fly, condition adaptable, fast set up, plenty of inside room for all your gear, military robust, packable bag, height for vertical kneeling/dressing/gear repair/preparation, no bailing out onto wet/snowy ground to get gear/dress, $75-150 excellent used condition,..... Take a look on YouTube for details, setup. A warm good nights sleep makes for an enjoyable hunt. Just a really, really old guy's preference........don't do uncomfortable anymore.
For slightly more......maybe +/- 45,000lbs........ at base in a 45' diesel pusher tag axle, towed Rubicon for ex-base roamer. AH, those heated floors on my old tired tootsies. Any more, I don't (primitive) camp; I luxuriate . YMMV......
