Dan asked a couple questions:
"How does the Instaflator attach nicely to a pad? I wouldn't mind using something to keep the moisture out of my Exped Synmat UL."
It comes with three fittings to fit various pad nozzles. The typical twist-to-close valve on a BA Air Core uses a simple plastic tube segment. I cut the others off to save weight, a whopping half ounce or so :-)

"The Instaflator seems like a neat idea. Do you inflate your pad from outside or inside of your shelter? From the video on their site, the instaflator looks pretty long, so you'd probably have to stand outside your tent and inflate it through the vestibule……which would be fine as long as it's not pouring rain."
In good weather I do it from outside. You can do it inside by not filling the Instaflator to its full length. It just takes an extra filling or two to get the pad inflated.
Either way, the Instaflator does about 95% of the work. I like my pad very firm, so I do a final puff by mouth.
