Hi all,
It seems that finally after months of searching I found a nice affordable brand of tents which can be ordered in Europe.
Now the problem lies between two models. They both have a 70 g/m2, 40d nylon 6.6 ripstop, silicone-coated both sides Flysheet, but one model is 5000mm (lightwave g20 trek) and the other one 3000mm (lightwave g20 ion). About the groundsheet, one is 135 g/m2, 150d polyester taffeta, 3-pass PU-coated (g20 ion), and the other one is 110 g/m2, 70d nylon taffeta, 3-pass PU-coated. Both 5000mm.
I'm not really sure what this means. I've been googling but I still wonder what's the practical difference. In the end for me it all sums up to a 50 euros difference and a 200g weight difference too. But I wonder if there's something else I'm missing.
I don't expect to encounter snow during my trips, but I do expect tons of wind and quite some rain.
Thank you

If I interpret the numbers correctly, the first flysheet is considerably more water resistant, with a somewhat more durable groundsheet.

That's what I've also thought of, but I'm not sure if it is really relevant or not. Another thing that confuses me is the groundsheet as I've read somewhere that nylon is way better than polyester.

Lightwave describes the Trek series as "4 season" and the Ion as "3 season" In other words the Trek will stand up to worse weather than the Ion so you need to think of what type of weather conditions you will have when you hike.

If I've got the correct tents and specs, the g20 ion and the t10 trek both have 70d nylon taffeta PU coated groundsheets rated at 5000mm of hydrostatic head. The t30 trek has a 150d polyester groundsheet. For the same denier, nylon is more abrasion resistant than polyester. But compared to 70d nylon, I would think 150d polyester would be more (maybe 50% more) abrasion resistant. But that comes with a weight penalty.
Both the g20 ion and the t10 trek have 40d nylon ripstop silicone coated (impregnated?) flysheets. The difference is that the ion is rated at 3000mm and the trek is rated at 5000mm. So the ion flysheet is less water resistant than the trek flysheet. I usually figure "waterproof" (for a fly) requires a minimum of 1500mm. Both flysheets are well over that. The trek would probably remain waterproof for more/harder use and in harsher conditions.
