Sub zero sleeping bag for under $50

Picture of Sub zero sleeping bag for under $50
You don’t need to spend $100 or more on a good winter sleeping bag to stay warm.  Especially when you will most likely only use it 2 or 3 times a year, and who wants to store that.   I’ve found after about 15 years of camping with the Boy Scouts in both Michigan, and Florida. This works much better.

Step 1:

Picture of
Items your going to need.

2 - 40* or warmer sleeping bags (if your sub 0* camping)
Or
40* sleeping bag and a polar fleece sleeping bag (the polar fleece bag will add about 25* to your bag)
And
A sewing needle
thick thread or embroidery floss
Scissors
Or
2-3 Diaper pens (they have to be diaper pens you can get them from the baby section at the store or like Babies R Us where they sell the cloth diapers, because regular safety pens come undone in the middle of the night and stick you!)

Step 2:

Picture of
Place one of your sleeping bags into the other one, if using a polar fleece bag place it into your regular sleeping bag.  Making sure to push the inner one tightly to the bottom of the outer one.  So the zippers are touching.

Step 3:

Picture of
Thread your thread or floss threw your needle.  Pulling the two ends together, Lick you index finger  then  wrap the thread three times around your finger. (if your using diaper pins skip ahead to step 11

Step 4:

Picture of
Then rub the thread down off your finger with your thumb. Then pull the ball you just made tight. You now have a large knot.

Step 5:

Picture of
Pinch your two sleeping bag’s zippers together at the bottom, then run your needle threw BOTH of the zippers just below the zipper into the cloth part of the zipper.

Step 6:

Picture of
Pull your thread half way threw the zipper, then take your needle threw the thread as shown, which is between the two pieces of thread that you tied into the knot.

Step 7:

Picture of
this will keep your knot from pulling threw the cloth in the night or undoing your sewing

Very nice, indeed! Simple and practical. I'm an Eagle Scout and can definitely appreciate the cost for camping and the struggles of cold weather camping.

If you go the diaper pin route, I found you can stuff both bag into your stuff sack, but if you sew them together I'd just roll them up because their too thick to stuff then, but ooohhhh sooooo warm. LOL
