James I just need to finish up my website and get a few more items in stock. I'm going to have a few regularly stocked items and also an option for custom work. I have fun making the custom stuff but it can be time consuming. I am very meticulous and I think its starting to show now that I have the right equipment.

I have the perfect idea for a valve. It will look absolutely professional and should weigh even less. It wont be good for large volume items like sleeping pads but a pillow is no problem. I'll keep you all posted. Anyway here is the little 16.6g guy all rolled up.


The palm reader said there was a pillow in my future?

I compared your pillow's dimensions to that of the Montbell's 2.4 oz pillow:

your pillow: 3.5" x 07.5" x 12.0"
your weight: 1.3 oz
cubic inches: 315
per cubic inch weight: 0.004126984

http://www.montbell.us/products/disp.php?cat_id=33&p_id=1124290

montbell's: 3.9" x 10.6" x 18.5"
montbell wt: 2.4 oz
cubic inches: 764.79
per cubic inch weight: 0.003138116

montbell is lighter per cubic inch by:
23.961027 percent

I doubt if it is due to fabric difference, it might be per overhead items like valve — wonder what else.

But Montbell's (I do own one and enjoy it) is only one size, and one shape. I like Bender's work!!!!

by per cubic inch, perhaps. But it's bigger. And heavier. I don't need the extra fabric. I'll take the overall lighter weight, and gear made by a craftsman instead of on an assembly line, any day.

Oh geez … buying this'll blow my rep for being a CHEAP B*STARD! (this plus the NeoAir)

But I'll rescind my earlier vote for a double thickness pillow in favor of what I'm saying next …

Pls, pls, PLS! keep extra material with a hole punched at all four (or three) corners. It'll allow me to fasten the pillow to the top of a belly pack (fanny pack worn in front) or clothing sack in order to build up height for when using a thicker sleeping pad.

Martin If I did a pillow the same exact dimensions it would only be 1.75 ounces including valve. If you calculate by volume you wont get an accurate picture of whats going on. It takes very little extra fabric to have a much larger volume.

To paraphrase Scotty … You canna change the laws of geometry, Roleigh!

For not-too-differently-shaped-volumes like this the larger volume item will have a lower surface area to volume ratio than the smaller one.

Do the math and you'll see that pretty much explains the diff you are reporting.

Also, each individual needs to evaluate for themselves how much value they'd get from the larger Montbell pillow. For myself, coming from a 1"x3"x4" foam pillow on top of a belly pack, this new one will be a nice step up!

Good idea, I never would have considered that.

Oh MAN I want one of those little rectangular units. Fantastic idea folks. Keep up the brainstorming!

I am tempted to try and make a pillow out of the leftovers from shortening my NeoAir (ala Steve Evans), but wondered if anyone else has tried something similar? And along those lines, what kind of glue is JB Weld? I have looked in several hardware stores and haven't found it, so I assume it is called something else in this part of the world. Is it a urethane glue? An epoxy glue? Silicone…??? Also, where does a person go to buy blow-up valves!

Lynn JB weld seems to work great for valves but I am now using something more flexible called Amazing Goop. The goop is contact cement/sealant that says it works well with plastics.

John I have been thinking about alternative valves especially for the pillows. I was thinking some vinyl tubing with a plastic Airsoft BB as a stop.

Here is what I made today! Its 12.2 oz for 72x20x2.5" and rolls up quite small. Believe it or not this is 70D nylon but the coating is light. I need better lighting for the picture of the entire pad.

I'd suggest silicon tube – less fragile over wider range of temperatures and a BB – too easy to lose perhaps?

THis may sound mad but what about heat welding a good lod fashioned blow up bed valve! The ones on 'water flotation party beds' Small, light, functional?

I had 46 yards of material to be delivered today but UPS decided to drop it off at the wrong address. UPS customer service had the audacity to tell me the driver had no way of being contacted because they don't carry phones. Not only do they have phones but the trucks can be tracked via GPS by UPS headquarters. I finally got a hold of the local UPS location and they called the driver so he is going to look for the package. I'm not holding my breath.

you may want to step out your front door and look down the street, especially at addresses that have the same digits as yours, but in a different order. my ups guy is notorious for delivering my stuff to 1636, and that guys stuff to my house at 1663.

Thanks guys I got the package. I did look all over but didn't find it because he put it between the screen door at the wrong address. I was looking for a box sitting out but it was just clear plastic over the bolt of fabric.

That's right this mummy pad is 8.2oz at 72x20x2.5". The two outer tubes are slightly larger so it cradles you.
