    I recon I'd need 2m of Tyvec 1442R to make one. This is on Ebay for £5.50 a metre plus £4 deliver. So the material itself would be £15.

    If that was 2m instead of 1.8m long I'd probably buy one, but as it is its too short. :(

    I've ordered one but agree it would have been better if 2m especially as I'm 6'2".

    Being a tent user, i've only had a damp sleeping bag at the foot from sliding down through the night and contacting the inner. Happened every trip last winter. 45g.
    A half protector should be adequate:-


    Decided to do a folded box end, easier to stitch...


    I'm not convinced at the longevity of this material:confused: i hope the 3F one is tougher whoever ordered it. Not sure i'll use it yet, but its there.

    Footbox looks good, could stick that together with tape, since the whole thing won't last long anyway. Is that what you did?

    No @Clare its stitched, my competent wife folds the end in such a way to create that shape. It leaves a triangular section at each end which is cut off.
    Whilst i look on with a stupid look on my face :)

    Did anyone who made one of these get around to using it?
    I did this weekend and it was a complete failure. Its not breathable at all. There was no moisture on the outside but inside my sleeping bag was absolutely drenched at the footbox.

    That's a shame. You must have a different type, the sheet I have is highly breathable. Maybe they changed suppliers. Yours looks quite shiny in the pics, the kind I used looks like garden fleece with a hint of shine.

    One side has a bit of gloss on it, the other is more matt. Its the ProDec Advance Dust Sheet i used - the one linked to earlier.

    Doesn't sound too wrong. Maybe it's wierd Northern sweat?:biggrin:

    Maybe my stock was faulty, there are micro holes all through it..easily visible when held up to the light. It's physically impossible for the stuf I used not to allow water vapour to pass through. I've used it as a liner inside non breathable Blizzard bags to keep my down jacket dry when sleeping in it.

    You said you wouldnt mention my sweaty Calf problem...:(

    I've just held it up to the light and theres no visible holes, and I've just tried holding it against my mouth and blowing through it and nothing is getting through. I gave up when i started feeling asphyxiated...:dead:

    I suspect the root cause of the 'Alt-dry' foot end has been found.

    Oh! That’s sad and bad. I wonder how people have got on with the Ali express tyvek version?

    Unsure to what Tyvek you have but the written side, is on the outside when applied to buildings.
    Personally I wouldn’t use it but have you tried making one out of 20 dwr material.

    I remember talking to Bob regarding this material maybe make one out of that material.

    That non-woven dust sheet is waterproof not breathable. Tyvek is supposed to be breathable but I've not tried my bag cover yet.

    Maybe zip up your waterproof breathable jacket and stick the foot end of your bag in that :banghead:

    No such probs with a mesh inner :sneaky:

    Just hope I don't get that problem with my new solid inner. (If I do I'll use my ul bivi)

    Tyvek comes in many different forms... From roofing, building, industrial and medical backgrounds...

    Cranston Thru Hiker 155 grams.
    The softest of the different tyveks-from the land of Oz. He is a much respected maker here.
    Should be cheap even delivered (30-40 pounds?)and give you a warmth boost you mentioned.
    Wash it a few times and it will quiet down even more-some say it's a wee bit noisy. Cheers.
