Reasons Why Tyvek Makes Sense As Survival Shelter
REASON #1: TYVEK SHELTERS ARE CHEAP
Cheap is important because survival isn't about glamor. The less money you have to spend on shelter per square foot, means you can buy more of it. Let me show you what I mean.
I have a Coleman Weathermaster tent. It's 9'x17'x6' high. So I'm getting 618 square feet for about $175.
In contrast, a 9'x150' roll of Tyvek is about $150. You're getting about 1350 square feet. That's twice the square footage for what you get with the Weathermaster.
Look, you wont be hauling around a 150' roll of anything in a survival situation. But I hope you can see the value difference.
Here's a second reason why Tyvek is a better choice.
REASON #2: TYVEK IS LIGHT
Let's take the WeatherMaster again. It weighs between 25-30 pounds. On the other hand, the same amount of Tyvek weighs under 5 pounds.
That's 1/5 the weight of the 6 man tent, just by using a different material. That will take quite a load off of your back. OK, we've covered price and weight. What's next? Protection against the elements.
REASON #3 : WATERPROOF
If you're wondering if Tyvek is waterproof or water resistant then check this out. Tyvek is not only a great home protector, but can be a great shelter, tarp, ground cloth and bivvy sack material. Let me share a real quick little lesson on waterproofness.
There's a measurement for "waterproofness". Its called Hydrostatic Head or HH. Waterproof fabrics all have a minimum HH rating of 1000. The rating stands for a column of water that's 1000 number of millimeters high. So HH of 1000 means a column of 1000 mm high can stand on the fabric before the fabric starts letting water through.
Again, 1000 HH is the lowest waterproof rating level. Most tent material is about HH 1200. Tyvek is about HH 2100. Its waterproof. And it's a great moisture barrier. But what do you do when Tyvek gets dirty and muddy?
REASON #4: WASHABLE
Here's something interesting. Most house wrap is biodegradable and disposable. And some types of Tyvek are even washable. You just throw them into a washing machine. Put the machine on delicate, throw in some liquid Tide and hot water and you're good to go. Just like clothing. At first it crinkles, and after a while it softens up.
So there you have it. Four great reasons why Tyvek makes sense as a tent, tarp and shelter material. At first I thought it was a joke when I heard about it. But the more I read, the more it made sense. Tyvek is indeed cheap, light, waterproof and its washable.
This week, go out and find yourself a 10x10' sheet. Pick up some Tyvek tape off of Amazon.
Then throw a quick bivvy sack together. Insert your sleeping bag. Go camping out in your back yard this weekend and tell me if it doesn't work great. And while you're at it, try coming up with your own Tyvek tent ideas and let me know what you discovered.
