OK, does inflating your BAIAC by mouth REALLY compromise the insulation? I'm not really concerned about moisture in the pad for summer trips, but winter trips is another story. Do I need to invest in the Pumphouse pump?
A corollary question is: How do you store your pad? Do you keep it inflated or store it in its sack? How does the moisture inside ever evaporate?
I think I recall reading in the instructions that the pad should be stored extended, not rolled up.Dec 12, 2008 at 9:09 am #1463893
I just lay mine out uninflated under the bed along with the thermarests. As far as moisture inside the pad. I've never really worried about it. I figure if it was a problem we'd have heard about it by now.Dec 12, 2008 at 11:00 am #1463920

RE: storage and moisture: same as Patrick for me.
I leave the valve open when in storage – don't know if it helps, but I feel better about it :)

Same here, layed flat under the bed, valve open.
Mine is the P.O.E. Max Thermo but same difference,
Synthetic insulation laminated to the inside top surface.Dec 12, 2008 at 11:22 am #1463926
Do you guys inflate by mouth?Dec 12, 2008 at 11:28 am #1463927
I inflate by mouth. The advantage of synthetic.
Although I must admit that DownMats are warmer
while also more expensive and heavier.Dec 12, 2008 at 11:33 am #1463929

Yes, inflate by mouth.Dec 12, 2008 at 12:01 pm #1463938
I inflate my Max Thermo by mouth. I've done so for 3 years. If that's bad for it, I haven't seen it. And if something happens, I'll buy a new one. I have no desire to carry a pump.Dec 12, 2008 at 12:35 pm #1463944
So my moisture concerns are unnecessary? Moisture won't compromise the PrimaLoft insulation in the wintertime? I am really worried about conductive heat loss through my pad. (I'll be taking a GG Thinlight just in case).Dec 12, 2008 at 12:51 pm #1463948
It may compromise it. All I'm saying is I don't think it does enough for me to worry about it. YMMV.Dec 12, 2008 at 12:51 pm #1463949
As you know, every sleeping pad has it's limits and just as all "winters" are not created equal, nor are sleeping pads.
I have always looked at "air mattress" type pads as providing lots of comfort and a little insulation. I carry them for that comfort. There are better choices if weight-to-warmth ratio is ones only goal.
Winter in the southeastern US isn't winter in New Hampshire and that isn't winter in the Canadian Klondike! So, I supplement my air mattress with CCF pads as needed for the expected conditions.Dec 13, 2008 at 6:56 pm #1464203

Michael is right – the BA Insulated Air Core and the Insulmat Max Thermo (I have both) are comfortable, but do not offer enough insulation for me below 30-40 degrees F. Any colder, and I use a supplementary closed cell pad. I sleep cold, so your mileage may vary.
I just inflate them by mouth, and leave them in their stuff sacks (after drying them out if they got wet).Dec 13, 2008 at 7:12 pm #1464204

I bought a BA Pumphouse Pad Pump when it came out last year. Unfortunately it is not nearly as all-purpose as BA claims. It is a failure as pillow–goes flat within an hour. It's a failure as a dry bag for even brief immersion–the water goes right through the fabric. However, it is great as a pump. Unfortunately I didn't test the dry bag and pillow configurations before taking it out on a trip, so I still have it. But it's not worth packing just as a pump.
I do use it at home, however. After a trip, I find some dry, warm air (if it's a cold damp day, I do this next to the heating duct or an electric heater) and pump it into the pad. I let it sit for 10 minutes, squeeze out the air, and pump in more warm dry air. Same procedure. The third time, I pump it about 1/4 or less. Instead of letting the mattress sit flat under my bed, I let it sit about 1/4 or less full of air with the valve closed.
The hope is that this will dry out any moisture that's in there from my blowing it up by mouth. I have no idea if this really works, though. At least it means that the Pumphouse isn't completely wasted.Dec 14, 2008 at 9:15 am #1464261

Perhaps return it anyway. Either the company needs feedback on an inferior product, or yours is damaged/defective.Dec 15, 2008 at 5:55 pm #1464591

As evidence to YMMV I winter camp with the big agnes IACP on snow and ice, down to fly camping in 0, never been cold
