Bivvy bag as Pod??

[mikewilkinson]

Just wondering, Has anybody taken a standard/cheap bivvy bag like this:-

And modded it to use as a pod.

I was thinking maybe put a hole in the bottom hem and sew in some shock cord, slip over the hammock use cord in hood end to pull tight around head end, leaving gap for breathing etc... Loosen off and slide back over hammock when not in use.

I know it won't be long enough to cover entire hammock, but should fit around the body no problems and provide some dead air space.

You could probably still use it on the ground, just pull shock cord real tight to seal of foot end.

I've got an old spare hanging around the garage and I always carry one in my bag just in case, might give it a try - any thoughts everybody??

Sure, that's been done a few times. Not just with a bivvy, but also sleeping bags.

Go for it, and post pics!

Wow, quick reply. Thats why I love this place, any advice on the modding?

Cut a ~6" hold in the foot rather than just enough for the cord to pass through - otherwise, you'll have good coverage at your feet and not enough under your shoulders.

Put shockcord on at least two places at the head end...at the shoulders. You'll get a little better coverage if you also put some on the hood. If you put it ONLY on the hood, you may not have good enough coverage on the sides b/c it'll sag.

At least that's how my sleeping bag worked.

It can be done and worked for me down to 11 degrees.
I used a mummy bag with hood, diced a hole in the foot end trimmed the hole with grosgrain. Shockcord both ends.

The slice and dice.

Engineer it so the zip is facing upwards. Allows the entry to be easier and zipper will allow for ventilation. The bag does restrict the hammock lay some. Still comfy, def warm. ymmv
This is a big sleeping bag and heavy, but works great.

The first time I ever slept "airborne" I slung a friend's eno through a big Coleman rectangular bag. Snored all night at 28 degrees.
