Well, I won't be hiding from the army draft, but I hopefully will be hidden from the drafts while sleeping under a tarp.
While tarping this winter, I was using a simple plastic sheet as a groundsheet. Light and simple, but I often found my feet sliding off the edge, and drafts while tarping in the winter can suck. So, I decided to fix my problems.
Its essentially a groundsheet with an uncovered footbox, adjustable side walls, and a pillow pocket to keep your noggin dry and happy. I like the pillow pocket because I can put small things up there like my headlamp, gloves, and any other miscellaneous items that I don't want migrating onto the ground during the night. Tapered at feet and head. Could be especially helpful when using a quilt. But, um Travis, why don't you just use a regular bivy? I'm not an incredibly sweaty dude, but for some reason I've always pumped out a lot of moisture at night while sleeping. I have no need for extra trapped moisture. Plus, it will be added splash protection.
I used regular silnylon, some cord locks, shock cord, and a wee bit of grosgrain for a loop for the shock cord. I'd like to thank John at Bear Paw for the incredibly fast shipping of my materials.
BTW, I hate silnylon. Sewing it sucks. Some of you are magicians with this stuff, but me? Some of my hems look like I did this drunk. However, the hems are sturdy and sound, so that's what really matters. Oh, and sorry for the crappy pictures. It's late here so my cell phone camera isn't too keen on the dim lighting.
Anyways, it was a learning project and I hope to try the real world practicality of this out soon. Comments welcome, but if you insult me, you owe me a case of beer. :)
Oh yeah......135 grams.
