>>1622417>What's the most UL setup available?What conditions? If you're somewhere dry and with sheltered camping then you probably aren't going to get lighter than a DCF poncho tarp and polycro groundsheet.
>227g for the tarp>~45g for the poly cro>my guy lines weight ~15gs>4 V pegs and 4 shep hooks ~75g>~360gDon't forget that it's a poncho so no rain jacket needed. Saving you an extra 170g-250g. You could probably shave some weight from the pegs by using carbon cores rather than V pegs but I can't be bothered to google the weights.
However, if you're heading out somewhere that's likely to get some actual weather you'll want to pair this with a bivy, you can get a nice one that weighs like 115g-155g. Even with the bivy you're still saving weight over a tarp+rain jacket combo.
Not my image but here is a shot of the poncho tarp pitched in an A frame.
