Hi DW. Ive got a Insulat Max Thermo 3/4 (now renamed the Ether, I think, but the tubular one with synthetic filling), an A/O Lite 2/3, and the Bozeman Torsolite which is also manufactured by them.
The Max Thermo lies between Thermarest and Exped downmats for warmth, but is lighter than a downmat. MoS has had trouble with hers deflating though.
The others are the equivalent of a Prolite 3.
And I've found that the actual weights are about 20% higher than they quote on their website, grrr!! (Except the Bozeman - that was accurate.)
