>>2365805Based off how thick they are, the heaviest they are using is 3.6, but it’s probably 2.5. It’s not that warm, similar to the polyester filling of a regular poncho liner (Apex is poly too), and it definitely doesn’t justify that price.
I’ve used my $30 poncho liner to sleep down to 50*F without any mid layer, just a base. A swagman isn’t magically 20* warmer.
