Couldn't resist title.
I recently got the old Thermarest Polar Ranger and the first thing I noticed is how claustrophobic it is. I got the long version which should accommodate 6' 6" (1.98m), but even at 6' 5" I'm completely jammed up on all sides (which may be because I'm 275lb/125kg).
Curious if anyone can help me out:
A) Is anyone familiar with the different models and able to speak on whether the extra inch of height and 3" width are noticeable on the newer one?
B) Are there any roomier alternatives that aren't super heavy and have similar features? Looking for those arm zips and something like the snorkel. Would definitely need to be below 0F, ideally -15 to -20F (-20 to -30ish C).
