Tyvek Bivy Sack // Does it work?

- Welcome. I decided to make a Bivvy sack out of Tyvek house wrap. I started with an 8' long by 6' wide and used Tyvek tape to tape up the bottom and side. I tapped both the inside and outside and only tapped about 4.5' of the side to make it easy to get in and out of. Right off the roll Tyvek is very noisy. A couple of ways to quiet it down is the wrinkle it up and/or put it in the washing machine for a couple cycles. This Bivvy is water proof, wind proof, weighs 10.8 oz and will increase the temperature of your sleep system 5⁰ to 10⁰. alot of of times you can find enough Tyvek in the dumpster from a construction sight to make this Bivvy. in contrast this Bivvy is much cheaper, lighter and stronger than some store bought ones.

Put the Tyvek in the washing machine for two cycles. Detergent not necessary. DO NOT PUT IN CLOTHES DRYER. After two washes the Tyvek will be soft and quiet.
Thank you. I'll give that a try.
Great job. I'll use this design for a bike trip in May 2024_ Hook of Holland to Konstanz.
It works well.
You might want to experiment with breathable, wind and water resistant heat reflective Tyvek14-S, from Quest Outfitters, reflects 90% of your body heat back to you. You can waterproof either or both sides and still maintain breathability. You also might consider using glue instead of tape for a reassuring bond. If you reply to me, I'll provide the name of a good adhesive.
I will definitely look into the Tyvek 14-S. I mostly use this inside a tent so I was not too concerned about it being waterproof. However I am always up to improve what I have. What type of adhesive do you recommend?
@@AmericaOutdoors1 Give 3M’s PLASTIC EMBLEM AND TRIM ADHESIVE a try. I occasionally mix it w/other glues - experimenting. It works best as a lap type joint fabric side to fabric side vs alum. side to alum. side. Then turn inside out with with fabric on outside. You might add a run of Acetone just prior to the glue or partially dilute the adhesive for best bonding as the fabric as you may know contains a fibrous material in the center of the Tyvek. You need to have the glue penetrate all layers of the sandwich construction to obtain the best bond and therefore the value of using acetone to achieve best penetration. What I’ve learned over a few years experimenting w/heat reflective Tyvek making all matters of clothing for hiking and bushcraft is that a base layer of polypropylene, Marino wool or Alpaca wool prior to wearing the Tyvek 14-S is best and then an insulating layer such as a wool sweater or a jacket/Anorak of goose down or synthetic insulation for Winter. You want to have the Tyvek as minimum distance away from the body but separated with a base layer preventing contact with the skin.
condensation?
Nothing yet. It works well and obviously I don't cover my head or it would condensate. Thanks for watching
is it waterproof, windproof, and warm to sleep in?
It is water proof and wind proof and pretty strong. It does add a little heat by trapping air inside but not much. I would add abug net if I was to use only this and not a tent.
@@AmericaOutdoors1 what's the hydrostatic head rating?
@@watch-Dominion-2018 Good question, I have no clue. I didn't know if tyvex is a cousin of gortex so they have similar property
@@AmericaOutdoors1 would tyvek work well as a groundsheet under a tent?
@@watch-Dominion-2018 It works VERY well. Its cheap, light and durable.
Use some Gorilla brand duct tape next time and it will be even more beefy. ;)
Thanks for the tip. I will try it on my next project. Thinking about making a large 2 person tent
It doesn't hold as well as the dedicated tyvek tape. Not even close.
The only tape to use is the Tyvek-branded tape with the backing paper. That stuff not only sticks very well but also does not go sticky and messy in the heat as duct tape will. The stuff being used in this video looks like some kind of plastic parcel tape and I have no idea how well it will work. For sure it will not work as well as the Tyvek tape with the backing paper you peel off before pressing it down in place, preferably with a hard roller onto a hard surface. That stuff is so strong that if you try to remove it, it generally takes the top layer of the Tyvek off with it, peeling the fabric in half.
Thanks for the tip! I will definitely try that stuff out. The tape I used in the video is regular type without the backing your talking about. The only part I am having some problems with is at the top part where the two pieces come togeather on the side. I think I may have to use some thread to sew it then tape over it.
