Building this for those late night setups in the dark after a long trek .
I should say we hope its good to 10 degrees . I will be testing it a lot so Ill report honestly how it does . I am a cold sleeper so if its' comfy for me chances are itll be more then enough for you .
Decided to build an insulated quilt for 3 and one half seasons . Trying to get down to about 10 degrees without augmenting the bottom insulation . Start by building a table 5 foot wide by 6 foot long so I can basically measure without having to use my brain if possible .
The basic hammock is made app 10 ' 6 " by 5 ' . I add iron on patches to sew quilt loops thru ,ala WVs method from the Hammock Forum .
Start laying out quilt . Using ultressa which is extremely breathable poly ester for first layer .
Iron a 2 inch hem onto the ultressa to tuck the 1 inch insulation into . It will be then sewn onto the underside of the hammock . 2 inches of width will be added to the quilt bottom so that in doesn't compress the insulation .
Adding temporary basting stitches about every 18 inches to test the hang .
Did a prelim hang in my messy old barn with the basted stitches to see how everything lay .
The foot end stiches ripped out from being too tight so I revised the bottom seam to give a lot more slack to the underquilt .
Made some marks on the hammock while I was laying in it to maximize the slack so that the insulation would lay uncompressed .
So what I came up with was a VEE shaped bottom hem about 10 inches above the straight line I had . This creates a bag for your body more or less .
So I enlisted the help of my willing little fabric monkey and we proceeded to sew all around the perimeter of the ultressa quilt .
So now we have a one inch thick quilt but with the very breathable poly on the outside . I decided to add another inch of insulation and a ripstop calendered layer on the exterior to help block the wind .
On this quilt I decided to sew it up first with a seam and then added it to the hammock .
So here I am laying in my insulated womb . Note the bungee cords in the outer seam to pull the sides around me in a cocoon fashion .
Ok full disclosure here . I made that gray ripstop a little too tight and compressed the insulation a little tighter then I wanted it . Dont' get me wrong it was toasty warm in my 35 degree barn but I might have to cut the bottom and add an expansion patch on the gray before I add my quilt loops .
Final weight 4 pounds 2 oz. . Cost app . 20 bucks in cheap insulation from Joan . Ultressa about 7 bucks from local Amish store . Ripstop from DIY hammocks about 30 bucks I think . Bungee from the Harbor Freight cargo net ( the gift that keeps on giving ) about 10 pr cent of that so about a buck .
