I use the pumpsac (actaully a UL schnozzle bag) supplied with the UL downmats. I use this bag also a s drybag for my sleeping bag. So far this worked for me. However 1 warning don't pull the compressed bag from your pack by grabbing it on the schnozzle. It might tear off...
Not particularly. Too many compromises to sate UL freaks who should be worrying more about the weight they're carrying around their waist than in their rucksack.
Well Dale you are hard to convince so I won't try. But check out the cottage stuff of seekoutside. They use honest to god good quality silnylon. No friggin compromise on weight there. Their carbon poles are sturdy and certainly not toothpick quality. So not reaully UL but leightweight enough to be interesting. Just suggestion to take a look that's all.
replace all guys with dyneema reflective cord from exped. it lights up as a christmas tree. Runners take the dark in the glow mini line loks of clamcleat.
Pegs - go import carbon pegs from Rutalocura. A couple of long ones for the most cardinal points of the tent, rest the short versions. The long ones are even good in soft peaty soil. They can be driven into rocky/grainy ground with some carefull hammering
Well the biggest advantage of a Cuben floor is that it's most certainly waterproof with a very high hydrostatic head. More than any other lightweight fabric that is being used as a floor. It also doesn't let damp go through the fabric. The only disadvantage is the abrasion, that's the achilles heel of cuben. But it can be solved with indeed a piece of polycro or thin Tyvek on the ground under the floor. A couple of stripes of silicone on the inside of the floor to prevent sliding abrasion of your mat on the floor.
This should take out the maximum possible time to use your tentfloor made of Cuben.
However that time is still limited compared with silnylon or even polyster PU. because every time you pack your tent in the stuff sack the cuben abrases against itself. That's why a cuben tent really looks liking being gone through hell after a usage on a long distance trail for let say a couple of months.
Is that still a problem? Not really, tears are easy taped and when it's finaly not anymore wateresistant it probably only consists of a tent made out of patches of cuben tape. Welll you the loose the weight advantage
