I'm considering getting one of these bad boys.

Here are my stats.

1.8m and hovering around 80kg.

Here are my requirements in order of priority.

Ability to go on month long or longer tours.
Full enclosure.
Cuben tarp.
Ability to go to ground if no trees are available.

What do I need? I dont wanna mess around with keeping warm so i'll opt from the offset for an underquilt and an overquilt. I want one of those Hennesey type covers to make it into a fully enclosed unit. Perhaps a poncho dual purpose thing.

Do I need an underquilt protector?

Recommendations on manufacturers please and available options. Ultralight. Cheers.
