The first prolite I got maybe 20 years ago was advertised at 16 ounces but it was actually 17 ounces.
They delaminate after a few years so I’ve replaced it several times. Each time it’s heavier. I think they keep trying to make it not delaminate, but that makes it heavier. The last one I got was 20 ounces.
20 x 72 x 1 inch – tapered
I threw a rock at my last prolite and punctured it
Therm-a-rest no longer makes prolite, but they have a “trail prolite”
$113, 20 x 72 x 2 inches, 24 ounces
I don’t like that it weighs 4 ounces more
The 2 inch thickness seems more comfortable than the 1 inch prolites so maybe it’s worth it.
It has foam strips inside. Horizontally. Glued to the bottom and top fabric.
In previous prolites, they had a sheet of foam with holes in it, glued to the bottom and top fabric. Maybe the horizontal strips is better. Maybe they don’t delaminate as much. But, my last prolite didn’t delaminate so maybe they’ve solved that problem.
I’ve used it on several trips and I’m okay with it so far.
I like it better than the uberlite. I don’t sleep good on it – it feels like I’m going to tip over.
It’s too bad it weighs 24 ounces.
It takes maybe 6 breaths of air to fill. My uberlite takes 30 breaths.  The old prolites took 3 breaths.
