Groundsheet

[Paulm]

A good soak in hot water fixes any annoying crinkling

I find tyvek okay but it gets overwhelmed too easily in soggy conditions

That's interesting you mention that Rich. A mate of mine used a new tyvek sheet as a groundsheet under his hammock for the first time on a trip last year and it tended to let moisture through when stood or knelt on. Don't know if all tyveks are made equal though or whether some grades or specs are more suited...?

The clear plastic sheeting is visqueen (usually pronounced "bisquick" here in the Southeast US) It's sold very cheaply in DIY stores and hardware/contractor supply stores. Like others have said, it's noisy for a ground sheet, but it has multitudes of uses in camp, on building/construction sites, at home, etc.

I second putting your mat into the bivi. Just rolling it up together at home. Save fitting inside if it's pouring.

Failing that. British army IPK sheet. Comes with 6 aluminium pegs which are good quallity. Check ebay.

Interesting, need to try that.
Ive never noticed water coming through mine, and i usually sit on it or kneel on it. There are diffrent types of it though, so some maybe better than others for a groundsheet.


I was looking in the screwfix catalogue earlier and theres quite a selection of thin clear plastic polypro stuff under painting supplies as carpet/window protectors, so may be worth a look if your after that sort of thing. Though you could probably get a groundsheet, tarp, tent and then cover your house out of a roll. So maybe not ideal

These are nice and £17 isn't what I would call a fortune. I have the small size that I use under my hammock but the medium is a good size for sleeping on.
