PD.........

After several posters complained about BA mats having seam seal issues I surmised it was probably due to hasty deflation and using excessive force...........so naturally I babied mine and did not use what I would consider excessive force when evacuating air. I also do all the business inside my tent to avoid briars and other sharp objects........

But alas........last time I used it I wound up on my buddies hardwood floor and had to reinflate a few times during the night. Throw in the lousy performance of the fill bag and the great reviews of the UL7 on various camping forums and how terrific their fill bag works and I didn't even check where the Big Agnes was leaking (Hey, interested in a Big Agnes mat ;) )
You have a Cuben Fiber fill bag? I want to hang out with you! We can take your private Jet to the airport in Ely. I was checking Cuben Fiber tents yesterday and thinking about getting one but the cheap ones start at 2K.........Ouch, crazy expensive! No thanks......

Anyways, glad your fill bag works great........maybe I didn't do something correctly. I like the UL7 as the valves mate perfectly.......zero hassle which is part of the MT creed.
