Ground sheets

A place to chat about gear and the philosphy of ultralight. Ultralight bushwalking or backpacking focuses on carrying the lightest and simplest kit. There is still a good focus on safety and skill.
Forum rules
Ultralight Bushwalking/backpacking is about more than just gear lists. Ultralight walkers carefully consider gear based on the environment they are entering, the weather forecast, their own skill, other people in the group. Gear and systems are tested and tweaked.
If you are new to this area then welcome - Please remember that although the same ultralight philosophy can be used in all environments that the specific gear and skill required will vary greatly. It is very dangerous to assume that you can just copy someone else's gear list, but you are encouraged to ask questions, learn and start reducing the pack weight and enjoying the freedom that comes.

Common words
Base pack backpacking the mass of the backpack and the gear inside - not including consumables such as food, water and fuel
light backpacking base weight less than 9.1kg
ultralight backpacking base weight less than 4.5kg
super-ultralight backpacking base weight less than 2.3kg
extreme-ultralight backpacking base weight less than 1.4kg

I’ve just retired my Gossamer Gear Polycro sheet. The tape patching the holes is starting to weigh more than the sheet!

What are you all using and where did you get it from?

I use plastic black damp proof lining for concrete floors used on construction sites from Bunnings or construction suppliers. It’s cheap, durable, 100% water proof, easily replaceable and can be cut to your tent floor shape. It comes in more than one thickness thin or thick.

ps just checked, there are digressions all over the shop-maybe look for my post/comments-might help.
If you find it in Aus. (I couldn't) post it up.

The thinner one. Visit and have a feel for which one is nice.

I cut a footprint for my first (heavy) bushwalk tent from black builders plastic.
Think it weighed close to a kilo so never used it! I probably chose a heavy weight plastic too...
Currently use a HD space blanket if I'm tarping, and/or a 1200mm tough ccf under my tent/airmat/bum pivot point.

My thin builders plastic perhaps 0.2mm thickness, 2x1m size weighs about 170g. I also sometimes use a Bunnings standard cheap blue tarp medium thickness of 1.8x1.2m size weighing 220g, which has metal eyelets at corners and also works quite well at around $6. I have thinner grade Bunnings tarps that may weigh even less.

Both compare well with standard 2 person tent footprints and ground sheets from Big Agnes, Vango, Sierra Designs etc at similar weights costing $40-99. Some BA UL footprints are around 110g for $85.

Simple research online shows the Gossamer Gear polycro sheet is from the US and it's the postage that makes it unworthy.

For those interested in the quality end of the market. Where the cost isn't necessarily top of the list of priorities. Where long term performance in the field is what really matters. I would vouch for the original space blanket. That's not one of these common, paper thin emergency space blankets you get for a pittance anywhere.
I've only ever found it imported by Ansco. It's the original US version. Costs close to $50. Oddly enough it depends on the packaging.

There have been copies over the last couple of decades. Kookaburra and Coghlans have both put out more affordable versions. Unfortunately, cheaper too. Through use they delaminate between the layers a little quicker. This can produce a ballooning effect. I think the Kookaburra one even omitted the eyelets which made manufacture less costly. It is certainly one outdoor product which can allow you to choose the level of quality and make a judgement based on your own frequency of use.
I still have in use some of the originals after twenty years. They are at least multi functional.
Ever on the search for a one ended stick.

I always consider the rubbish factor (end of life) for a product choice, and it's actual effectiveness.
And material/manufacture, origin, size, weight... a fussy shopper!

You'll buy polycro (window film) locally /or ebay.
50um clear builders film you can buy at 2m wide.
Grabber space blankets are good, we use these, but in another weight category v's polycro.

We've used these and more, but i've no strong preference. A balance with what tent floor you have, is one necessary?. I find Polycro and Tyvek are a awkward to handle.

If spending big on Cuben tent, a similar cuben groundsheet works/is light. Then again a Cuben floor is easy to tape /repair (I don't bother with a groundsheet with my own little tent).

Under $20 AUD and similar quality to my MSR groundsheet that was 3x the price. Not particularly lightweight but well made and cheap, with lots of sizes available from the same manufacturer/seller by the looks of it.

moisture proof?.. like a blue tarp or a $14 tent floor.

(I'd try a bargain tent but they are always only 1.9m long)

Time to fold out my tyvek piece and make a bathtub gs :)
