I have been using a couple of the Stearns self inflating sleeping pads for our camping. They are a four compartment pad. The attached pillow/head pad must be inflated manually.
They are 21" wide and 75" long. They have served us well and have never needed repair. I like the triple compartment self inflators. They air up quickly and allow different pressures for shoulders, hips and legs. They roll up into a nice small package.
I recently found out that there are double wide self inflating pads available.
Trail-Gear had an excellent price
These pads take a much longer time to inflate. They are a single compartment with soft foam interior. I like the brass valve for inflation. The pads are wider and longer. The single measures 78"x25" and the double is 78"x57".
The double pad is two compartments. This would allow it to be folded lengthwise for a double thick sleeping pad. That is something I had not considered before making the purchase.
Right now I am still basking in the glory of being treated so well by the Trail-Gear Inc. customer support. My impressions of the product may be biased right now, but I really like them so far.
Sleeping comfort is one of my "special things". I allow it to take up more space and weight. Comfort while sleeping is a luxury item and not subject to the same size and weight limits I set for other gear, within reason. The new pads appear to be about 25% larger when bagged.
I have not packed these yet, nor have I slept on them. the 1.5" thickness has always bee enough pad since I pack a big thick Coleman bag. I will say the extra three inches of width will be nice, as will having a double wide pad. I wasn't crazy about the inflated head pad on the Stearns. The Trail-Gear pad looks to be a wonderful improvement. All pads came with a repair kit, straps and a storage bag.
I store my pads and bags opened up and laid out. This limits the crushing of foam and fibers to the time packed and transported.
At this point I would say that the Trail-Gear sleeping pads are a very good "bang for the buck" if you have the room, get the double wide pad. It would be nice to have the option of wider or thicker if needed. Even for a single adult.
