It's always a struggle to get my wife to hike w/ me because she doesn't sleep well on the pads I have. I own two Big Agnes IAC's which are super comfy, but not wide enough for her at 20". So, I decided to make her one(see below)....She loves it!
Fabric - I tried a couple different sources for the fabric. The first I tried was very light, but the heat seal coating was hard to work with. This fabric was from Quest or Owfinc, I will have to look. The fabric I ended up with was 70D from Rockywoods. It's a lot heavier unfortunately, but quality stuff. I will most likely end up making another one for her out of the lighter material. For comparison, the other pad I made was a mummy 72"x20" with 2 oz of 800 fill. Final weight on it was 12.2 oz.
Valve - I wanted a better valve than the Big Ag so that took some looking. I tried both a Thermarest valve and a urethane valve I found. I went with the urethane valve because it's MUCH easier to inflate/deflate the pad & is only 3g heavier than the Thermarest valve. On the DAM I made it takes about 20 secs to deflate compared to some DAMS I've heard taking several minutes. Granted, these valves aren't as clean looking, but I'm about functionality.
Overall, I'm happy with it and so is my wife. She is willing to hike with me more often now, which makes me happy. And in turn means that we can split the load on trips(hence the title of this thread. lol). Any questions let me know.
