hand made, in NH is Warmlight.. tunnel tents ,in the case of their 3 person one is 12' long.
from one cone shaped end and door to the other, that long enough?

comfort requirement? thin closed cell foam pads pack small , weigh little,

OTOH, insulated air mattresses are lots more comfortable..

i liked the Down Filled airmattress If only the Coatings for sealing
were not vulnerable to mildew, from being inflated when the RH and Temperature were
conspiring to be no less moist than if I blew it up by mouth.

Dry Summer or Snow camping no problems..

Exped may be different IDK.. I got one of their heavier foam plug filled ones.

Marmot CBS -component bag system,, rectangular matching zipper with
the zip cover over the Matt,as a Bag bottom works, because I'm a side sleeper..
and I hate a tight a mummy bag..
