WHICH TYVEK FOR FOOTPRINT?

It's the tyvec used as a home wrap the clothing variety isn't as durable. The homewrap type is 1.9 ounces per square yard

Plain spinnaker cloth worked fine for me.

the house wrap is what I use for a couple of groundsheets for car camping with scouts.

I dont understand the "pick up dirt" thing. The housewrap is slick, it doesnt pick up dirt. None of mine have been washed in washer to soften and quiet though.

It is however, relatively heavy. 48x 84 runs about 8 oz I recall. Replacing polycro every trip, or going without, seems like a decent option by comparison.

Just used some housewrap for a barrier over a bed mattress for my little niece in her case
pullups over flowed. Well even the small amount that made it past the huggies also went
right through the tyvek.

This was new but washed once and line dried.

Take the weight of the TYVEC to zero. Don't use anything, it's a tent with a floor right? Just take a few extra seconds to clean out any pointy sticks or rocks, you'll be fine.

There are several types of Home Wrap.
The type I use (t41081) would be about 6oz for a 48×84 piece.

(I should have said "I have" , because I don't use it in the bush. I also have T34052 (maybe a bit lighter) and T24103 )

I've used Tyvek HomeWrap as well. I don't know which specific type, though. Started out crinkly and stiff, but made soft and quiet by running it through the a washing machine (no soap, if that wasn't obvious) and line drying.

It's very slick, and doesn't pick up dirt at all. It does seem to be sticky to pine needles and dry leaves, but they're easily brushed off.

My only beef with Tyvek as a material for a floor or ground sheet is that it's slippery, though no worse than silnylon or polycro. It's not the lightest, either. But it's low cost, durable, and relatively light.

… after consideering your comments on Tyvek I'll try some spinnaker cloth for the TT Moment footprint.

I'll likely sew on some Velcro wraps at a few corners to keep it in place on windy days. Seems like the most durable light footprint (other than Cuben) that I could use.

But Tyvek footprints for sure on my other two "car camping" tents.

Thanks guys.

P.S. Bob, where'd you get your spinnaker cloth footprint, Seattle Fabrics?

I did not buy any footprint. I bought spinnaker fabric and sewed up something with corners. It came from Prolite Gear.

–B.G.–

I begged some (non-Dupont, as it turned out) housewrap and made a footprint for my (then new) BA Fly Creek 2. It turned out to be significantly heavier than the factory footprint, which I bought for the fast fly option. Haven't used fast fly yet (too buggy in summer, and I appreciate the extra warmth in winter) but I like the factory footprint because if it's raining I can keep the tent body dry by setting up in fast fly mode, then deploying the inner under cover.

Bob,

That's what I meant, just the fabric. I've made one footprint several years ago W/ elastic loops at the corners to keep it in place in winds when I wasn't in the tent so I'm OK with sewing my own.

Seattle Fabrics only sells fabric from the roll. I'll look at Prolite Gear as well.

Thanks
BTW, perhaps I'll coat the spinnaker cloth with a 5:1 mix of odorless mineral spirits to clear GE Silicone II for very light waterproofing. Worked great on my Moment.
