Duomid inner floor material?

[DannyS]

I have a Duomid arriving soon and am looking at floor linings, I'll mainly be using a bivy bag with it although I have the inner net also.
I was thinking of using Tyvek as I hear it is hard wearing and light, but I'm wondering if it has any water resistance at all and whether that is something that would be necessary for this set up?
Otherwise I'm open to suggestions of any other light weight possibilities?
Thanks.

Thanks ULWalkingPhil looks like I'll go with Tyvek then, can you tell me if it offers any water resistance at all? How many meters did you require?
Cheers

I purchased 2 or 3 meters from the forum here and cut it down just a bit smaller than my Oooknest inner. So far I've found it water proof enough to lay on in the wet. I don't know what it would be like on top of a puddle of water. I'm very careful with site selection.

I heard many are receiving there orders from MLD in 4 weeks of late, even though they been informed that there is a waiting list of 8 to 10 weeks. I don't want to get your hopes up to high, but you never know. I received mine in 6 weeks, was informed it would be 10 weeks when ordered.

Thanks ULWalkingPhil, this one has been on order for at least a couple of months. Ron notified me a few days ago that everything is ready to ship, they're on break till the 27th so expect they'll ship it then. How long approximately did shipping take for you?

[Lady McGuyver]

Hmmm..don't get your hopes up there. I ordered over 10 weeks ago and was told this morning it will be made in a few weeks...so there's another month waiting
At least their gear is worth waiting for!
Danny, Pm sent re Tyvek too

[ULWalkingPhil]

I had Ron send the DuoMid to my mail forwarder in the states. Got my mail forwarder to send via FedEx Express, it arrived in 3 or 4 days to my door from California. It all depends which service Ron uses to post overseas. USPS priority Mail is slow, USPS express is not bad. Fedex is quick.

I am currently waiting on a few packages from the states that was sent via USPS Priority two weeks ago so far nothing's showed up.

Thanks for the heads up, as I'm planning a four week thru hike based on this package I think I had better contact him and make better postage arrangements.
Thanks for your help ULWalkingPhil, all the best.

Yes

Sorry, I was offering that as a potential floor material.

Oh I misread that Strider, I'll get a quote out of interest but I'm certain it will be too expensive.

I thnk if pressure is put on Tyvek then it's not waterproof (read from other's reports, not first hand knowledge sorry). Just from memory, just about to go to bed.
I've cut footprints fo tyvek for all our lightweight tents, or ordered them with one, been happy with it so far.
Crinkly and stiff at first, it softens up
You can wash it in the washing machine I have read, not needed to do that with any of ours so far.

Polycryo is worth considering. It's waterproof and lighter than Tyvek but it's not as durable.

I've had a bit of a look around, do you know if Polycro is available in Australia?

[ULWalkingPhil]

Maybe one of those silver emergency blankets might make a good ground sheet. I've never tried one as a ground sheet, not sure if there water proof.

I would be surprised if it isn't available in Australia. It's intended purpose is as a shrink film for insulating windows. The question is, just like with Tyvek, whether you can find a small piece for a reasonable price. Here in the U.S. window insulation kits are sold in hardware stores and can also be ordered from amazon.com. Gossamer Gear also sells small pieces of polycryo. It comes in different weights but the stuff I have is about 19 g/sq m.

Another option is polyethelene plastic sheeting that is sold as painter's dropcloths. It's inexpensive and it comes in a variety of thicknesses. For each thousandth of an inch thickness (25 microns) the weight goes up by about 24 g/sq m. I've used the 25 micron thickness and it usually had a new hole every night, which I would dutifully put a piece of tape over. The 75 micron stuff is pretty durable but also kind of heavy.

I've never used Tyvek, at least not as a groundsheet, but it must be popular for some reason.

Thanks Orion

I'll have a look into that today, Cheers.

Of course they're waterproof -- they're intended for emergency bivies. There is more than one type of emergency blanket product. The original ultra-small ones were metalized mylar and would tear if they brushed up against a rock. I've only slept under them when caught out and I sure wouldn't trust one as a groundsheet. Plus they don't fold back up very well so they're bulky once you use one. There is another type that is metalized polyethelene. They're a little heavier. I haven't used one but handling it makes me think it's probably more durable (and easier to fold up and reuse), but I doubt it's much more durable than unmetalized polyethelene of the same weight.

Thanks Orion, I'll have a look into the availability of Polycro today otherwise I think I'll just stick with the Tyvek.
