Bivy Pattern on 02/17/2009 11:20:52 MST Print View

I have been considering making my own bivy and have been playing a bit with patterns for it. I started with the SMD pattern they have on their website and modified it to fit my intent.

I think I will start with making it out of Tyvek just to see how it shapes up. I am thinking I might even add a zipper to the full length across the top so that I can open it up for venting as needed. It would zip open from both the bottom and the top.

For you MYOG people, check out my pattern and please offer some suggestions if you get a chance.

Did you see this thread? I wonder if Mateusz still has his plans, or if he sent them to Dave as discussed in the thread?

I did see that post... I do like the idea of having more of a bathtub bottom. I might have to play around with my pattern a little more and see if I can redesign it that way. I also like the idea of having the zipper on top with a double zipper. Especially with using Tyvek, it seems like you would want it to be able to vent it a little more. I would definitely only use it under a tarp with the zipper on top...

Mateuze did respond, but with an offer to make one for me. His goal looks to become a UL equipment provider in Europe, so I guess he's holding on to his bivy pattern. It was a nice design, but I was more interested in making one than buying one.

to make the floor tub you can add 3" to each side of the bottom piece, above the foot half circle and remove 3" from each side of the top piece. Sew the top to the bottom then sew up the foot and you will have tub sides without changing your patter much at all. You could also bring the extra 3" around the head if you wish.

If i was going to make a bivy i would skip the curved footbox and make it square like the bottom of a stuff sack. Sew the mesh to the top then the top/mesh to the bottom on sides and bottom. Then sew the little triangles on the bottom to make it 3d(see stuff sack instructions) I would just add a drawcord tube at the top to get in and out. You could also put a zipper in one of the side seams if you really wanted. Large patters are hard to put together, it is easy to make rectangles.
