Summer Poly Fill Quilt

if cost is an issue get climashield green 3oz and 1.1 2nds from OWFINC.com The insulation is much wider so the width can become the lenght of your quilt meaning you only need 2 yds not 2.5. If you cut it right those 2 yds may make 2 bags depending on the size you use. The 3oz is a bit heavier but should be a good deal cheaper.

If you can find a reason to buy 20yds of ripstop (1.1 breathable, sil or 1.9 can all be mixed (maybe even the 4oz rip)) you can get your entire order at wholesale.

1. Your dimensions of 80" long, 54" wide at the top and 38" wide at the bottom, basically give your pattern. Cut out or fold a piece of sheet to see if it's right for you.

I looked at that sleeping bag and had the same thought, cut it down a little and get a sub 1 lb quilt. It may not be all that warm, but OK for warm temps.

Since you're going to have a light quilt from the cheapo sleeping bag, why not make a warmer quilt using something like thru-hiker.com climashield?

Tim's right, that http://www.owfinc.com/Fabrics/insulation.asp
climashield is 102" WIDE!!! Neat!

I just built a test run quilt out of 2nds lw ripstop from walmart and some regular 3/8 polyester batt and velcro from joanns. Less than $20.

I am 6'-3". I built it tapered top and bottom flat sides, 7' long with velcro at the foot/bottom, and a drawstring foot box. If you had a regular foot box you could make it shorter. Actually with a drawstring type I think I would like mine more like 1' longer than me.

I wanted to be able to open it all the way, thus the velcro and drawstring.

Its probably good for 60dF.

It works great, but the footbox being a drawstring type and tapered at the foot is slightly too tight. It would be better with a flared foot area where your feet end up.

If the bottom is open, IE tube, no problem. Of course if its open like a blanket it does not matter either.

If you want, I can post a pic or two.

You can often get the EN 13537 European Standard Ratings for sleeping bags, even if the American retailers only furnish "American" values.

Do a google search for "EN 13537 name/model of sleeping bag",

For example "EN 13537 Lafuma Extreme 600".

This returns, in different languages, information like

Komfort 16C
Limit 13C
Extreme 2C

Meaning that the limit of comfort for a male according to the European test method would be 13C or about 55F.

You could "survive" at as low as maybe 35F or 2C.

This doesn't work for many US "marketed" bags such as TNF or REI.

Such strong American (honest) marketeers refuse to use those "socialistic" unfriendly conservative ratings that those wimpy Europeans use.
