MYOG Sleeping pad 2.0 – Down action

Way to go Ryan! How did you seal the chambers?

Looks great.

Very nice

quite lightweight also

How did you do the valve?

Hi Todd,

I cut 66"x.25" strips out of the nylon and sewed the cuben in between for the baffles, then heat sealed them. It was a huge pain for saving probably 2 oz. but I just mostly wanted to see how it worked out. With that being said most likely will not be doing that again.

Jerry,

I used an Airtime kite valve which I had previously used on the outside of the pad. Basically, just cut a round hole in the fabric & then it glues over it. On this one I instead used Seamgrip to glue the valve to the underside of the fabric so only the mouth piece is visible up through the hole in the fabric. Kind of hard to visualize. It just looks a little cleaner. Those valves only weigh 2 grams more than a Thermarest valve, but flow a ton more air which really helps deflation. Used nano-see-um to keep the down from escaping.

Haven’t tried one myself, but thought a lot about it.

Stretchlon is still readily available at a reasonable price and weight.
