Anyone ever have trouble inflating Exped pads with built in hand pump in bitter cold weather?? Have a buddy interested in getting the Exped 9,, and his concern is in -20F or colder that the pump may malfunction.
Issues??

I have used mine at temps in the teens, built in hand pump, noticed no change in pumping action.

I used my DLX9 last January in below zero temps and didn't have any issues - worked fine. Remember there is no mositure from blowing it up like some do with thermarest style pads

I've not experienced any problems.

Same here, two 9DLX's with no issues in below 0 temps.

I like the idea of that hand pump, I have the older version where you use the bag that the Exped comes in to pump the pad

Also have used a couple of the 9DLX for the last several years. Cold has never been an issue with the hand pump.

I have however started using the EXPED Schnozzle with the 9DLX adapter to speed up inflation. Much quicker inflation time and the Schnozzle also doubles as a large compression bag etc.

I haven't tried the adapter yet with my 9DLX's. I picked up the schnozzle earlier this summer with a few Exped 7 UL's, and they are a breeze to inflate. Will have to get the adapter to use this winter!

My friends Mark, Greg (SevenofNine) and myself all had Exped mats on our trip last month. While I can't say with absolute certainty what the temperature was at time of inflation; we did have temperatures that exceeded -30 F on our trip. No one mentioned having any problems what so ever.

I pumped mine up at 20 below. It takes a little longer, but still works just fine. The main tip I'd give you is to unpack it a little while before you want to pump it up - the piece of foam inside that makes the pump chamber "bounce back" takes longer to get to a useful size in the cold.

I did have trouble with inflating mine. I ended up putting my mat in the sun to warm and that helped some. However, I ended up just kind of working the air in until the pump somewhat worked. Biggest issue was the deinflation valve froze on me so I folded my mat in threes and strapped it to my sled to haul out. If you are hot tenting I don't see a problem. I was not.

No problems inflating...had the same prob as SevenofNine. Used a Buddy Heater to thaw valve.
