@c531994e ahh, you beat me to it!

Rather than my own first impressions post, Ill instead tag along.

1) The new two-piece one-way valve is great.  Anyone who has inflated a mattress by lung above 5000' after a very long day knows this pain.

2) The extra 0.5" thickness may not seem like much, but for this side sleeper, it made a difference.

 @3c96a629 @a7528bff I like the idea of defining ultralight as 10% or less of your bodyweight.

At one point,  my base weight was 10 lbs for 3 seasons (13 for winter), but as I have gotten older I have allowed a few comfort niceties to slip in.  It has made a world of difference, and I'm only up to 12 lbs. 

 @c531994e @c02fb0a2 Looks like it was a heck of a trip.  Thanks so much for the wrap up!
