I’ve had very few problems with any sleeping pad I’ve tried. Some have deflated, but I’ve never had one deflate (knock on wood). That said, there are other ways to get a better night’s sleep and have a more enjoyable trip.
Do not expand the pad over your mouth: For one thing, some of these sheets are big, and they just hurt, and your air is warm and humid and you’re injecting nylon, which is a way to get rid of mildew and mold. This concern may be overblown—a few people have cut open sheets of paper they’ve added to their mouths over the years and never found a sign of mold—but considering the pain involved, it seems easy to avoid. Most manufacturers include some type of pump bag these days, which makes it quick work to inflate your pad. There are also fire pumps that only weigh an hour or two, such as Flextail pump.
Don’t make it too big: Air-tight insulation works by putting air and materials between you and the cold environment, but that doesn’t mean you have to piss it off until it’s gone. It varies by pad. I usually find that the best way is to smoke it taut, then start exhaling, and lie down to practice until you get to the point where you feel comfortable. The downside of this method is that your pad isn’t thick enough and you may fall off if you exhale too much. I find that this is not a big issue for stomach or back sleepers, but if you are a side sleeper it may take some time to find the sweet spot between comfort and warmth.
Pick up the patch kit: Most sleeping pads today have a patch material. I usually don’t bring these tools with me instead I carry a small notebook of Tenacious Tape ($6)which will eliminate rips and tears in everything from sleeping bags to tents. Be sure to test a small piece of your tape ahead of time to make sure the tape will stick, and bring an alcohol wipe to clean the affected area.
Women need high R-value sheets: Women generally have a smaller body mass than men, which means women will need to add about 1 R-value to achieve the same level of insulation. (I also recommend raising the R value if you are a sleeper enough.)
Sleeping bag sizes are based on R5 pads: Most of the things you see on sleeping bags are true if you’re using a sleeping bag with an R-value of 5 or higher (they also assume you’re wearing the basics). If your pad is too small, you should adjust the temperature of your sleeping bag accordingly. For example, using your 30 degree quilt with R4 pad can leave you cold if you are experiencing cold. In that case you may want to raise the R value of the pad, or bring a warm sleeping bag.
