3m (3.2 Yards) of Tyvek 43gsm 1443R Kitemaking Material | Durable, Strong, Lightweight, Breathable

The 3m (3.2 Yards) of Tyvek 43gsm 1443R Kitemaking material is a perfect choice for a lightweight, compact, easy-to-pack groundsheet. The exact size I received was 10.5' x 5', which is plenty of length to accommodate 3 or 4 adults laying next to each other, parallel to the 5' dimension. I'm 6' tall, so my feet hang off the end by approximately 12", but that's actually convenient since it naturally encourages me to keep my feet (i.e., boots/shoes) off the groundcloth, increasing its life span and reducing how quickly it gets dirty. At night, when I take off my shoes to climb into my sleeping bag, my full-length sleeping pad supports my feet to get them off the ground in damp conditions as well.This 1443R material is, in my opinion, superior to the thicker house wrap type of Tyvek that many other backpackers use as groundcloth material. First, it is MUCH quieter without need to do the dryer trick to "break in" the material. That makes it a lot nicer to lay on at night. Second, it is lighter. My scale reports a total weight of 215 grams (7.6 oz.) for the full 10.5' x 5' piece. Third, it's a little easier and slimmer to fold up and stow in a pack (the thinner material "fights" you less). Yet the performance and durability still seem plenty adequate for a groundcloth. In fact, I find this to be the best all-around compromise between the ultra-light (but obnoxious to handle) polycro ground cloths and the heavier, loud (crinkly) house wrap style Tyvek. It's not as compact as polycro, of course, but my 10.5' x 5' piece folds down to roughly the same size/thickness as a folded Hanes Men's undershirt. Finding a spot in your pack for it should not be a problem.Only time will tell how durable this will be, but on dirt/grass, I suspect it will last for a very long time. Just watch out for sharp rocks, thorns, or sticks, which should always be cleared away before setting up camp.The white color shows dirt easily, but I like that it also increase the perceived brightness in the interior of my teepee style tent (I use a BearPaw Wilderness Designs Luna 4 shelter). In case you're interested, I cut my piece to 8' x 5' so that it will be even lighter and more packable, but still just large enough to squeeze four adults shoulder to shoulder onto the groundcloth. In practice, I use it for myself and my three little girls--ages 1, 3, and 5--so it's plenty spacious for that purpose. This leaves me with an additional 2.5' x 5' piece that I can leave at home to save weight, or that can be used as a minimalist solo groundcloth, or that can be used as a handy picnic blanket for keeping food items clean at lunch time and/or keeping your butt dry and clean when you sit on wet ground.If you're looking for an affordable, lightweight, easily packable, fairly durable groundcloth, this one is very hard to beat--a great value at $16. Highly recommended!

This makes a great lightweight ground sheet to protect the bottom of a tent. It's waterproof and will help keep your tent from getting punctured. Cut to size (just a little smaller than the bottom of your tent so it doesn't hang out).If you run it through the washing machine, it softens up and has very little crinkle sound. The best part is, if it gets really dirty and nasty on a trip, you can blast it with the hose or just toss it in the washer.

This is interesting material. Really light and more durable than I expected. I used the material for a ground cloth. It serves that purpose well. I camped on gravel, grass, dirt/mud and no problems. I am going to wash it to get the dirt off. The other good thing is the material stuffs well. I put it right in the tent stuff sack with the tent.

I use this as a footprint for my tent when backpacking. Works great and is so much lighter than the standard issue ones that come with your tent. I put grommets in the corners and now it can be used as a tarp as well. It doesn't stay very clean, but it's going under the tent so why do I care? I appreciate that it's not covered in logos like other products, and it feels like a soft fabric, not crunchy.

I tested this stuff with standing water on the surface, and it seemed to do just fine. Also I couldn't rip it with my bare hands, which admittedly may not mean very much, but anyway...Also, it is very light (I'm planning to use it as a backpacking ground cloth/tarp) and not to terribly difficult to fold back down to about the size of the package it came in, which was probably ~7" x ~4" x ~.75".

Perfect ground cloth for our backpacking trip.

I use this as an all purpose sheet for when I backpack. It is waterproof and makes a great protective layer between the ground and your tent during the night. It can also be used to sit and spread gear on damp ground as well as loosely hung to provide light shelter in rain. For the price, weight, and utility this is an amazing deal. Just be careful, while not flimsy the fabric could definitely tear and should be used with care.

I purchased this to turn it into a lightweight groundcloth for my 1-person backpacking tent. It was much more material than I needed. I'll be able to make a second groundcloth for my tent, once the current one gets retired.I used the groundcloth on a backpacking trip with very strong winds. Since it's so lightweight, it was hard to get it to stay in place (blowing around like crazy). I'll probably add some little tabs on the corners to hold it in place for my next trip.
