For the last 10 years or so, I have been using a Therma-Rest Prolite Plus that weighs in at about 23 oz. This seems like a good place for me to lose some weight.

What do you recommend?

I'm a section hiker, maybe 20 nights a year on the trail, mostly 3-season so I'm looking more for comfort than insulation. I sometimes stay in shelters but mostly use an REI Superlight Bivy.

TIA
