I own several Thermarest inflatable matresses (& returned a Neo-Air. Long story.).

Also I have a RidgeRest CCF.

For summer camping I use Thermarest's 1st lightweight inflatable, the "Lite", reg. length. It's over 10 years old but still works well even at 25 F..

But, for week long winter trips I'd take the Trail Pro AND the RidgeRest because after several days you get so much vapor in the Trail Pro that it loses much of its insulative value.

CLEARLY Cascade Designs/Thermarest needs a lightweight pump to attatch to their Thermarest mattress valves to keep breath vapor out during winter use.
