Hi - are there any polyester experts out there who can explain the physical difference between 75 and 100 denier polyester?
We have just returned from our first 5 night trip in our new Filey 6 and, whilst we really love the tent, I have to say that I don't understand Kampa's claim that the flysheet is better quality and more tear resistant than their competitors materials.
We also have an Outwell Sun Valley and recently sold our Outwell Idaho XL.
If anything I think the material on the Outwell's felt thicker.
Any thoughts?

Denier is a unit of measure for the linear mass density of fibers. It is defined as the mass in grams per 9,000 meters. In the International System of Units the tex is used instead (see below). The denier is based on a natural standard: a single strand of silk is one denier. A 9,000 meter strand of silk weighs one gram. The term denier is from a French coin of small value (worth 1/12 of a sou). Applied to yarn, a denier was held to be equal in weight to 1/24 oz.
If that makes sense

The higher the denier the longer it will last under UV exposure (potentially double for the increase from 75 denier to 100 denier - as the survival rate in outdoor tent displays demonstrates - also see quote below). This is a natural property of the denier and Kampa even add an extra UV resistant coating too.
The 100 denier is definitely heavier/ thicker/ more dense than the 75 denier (although not as heavy/thick as polycotton or cotton) as explained by the above information from Arsenaldes. We have both 75 and 100 denier tents and it is certainly noticable when they are compared, although the way the fibres are combined can make one feel thicker than another despite having the same denier properties (which probably explains your perceptions re. your Outwell tents).
Just as outdoor clothing is made from higher denier material than normal clothing, the higher the denier the flysheet the more robust it naturally is - hence the claim that the Kampa flysheet is more robust. It will resistant tearing and abrasions much better.
Quote: "75D Polyester is 10-20% stronger than 70D nylon, and has 30% longer life under UV exposure. 150D Polyester is 50% stronger than 70D nylon, and has 200% longer life under UV exposure." ....
Hope that helps...
------------- Love our set-up and need no more tents or gear, so trying to stop looking!
Nice tents Kampas glad your pleased with it. Check with a female regards Denier as well tights and stockings are sold by Denier best to check when they are not wearing though

We are thinking of swapping our Outwell Sunvalley 8 which has served us very well for the past three years for the Kampa Filey or Kampa Holkham are we doing the right thing?
I would say so yes Neets. We found our sun valley 8 to be a bit scary in the wind but we loved the size and layout.
The alloy poles on the Kampa did much better during the recent windy bank holiday and the layout is very similar. Obviously the Kampa is not as long as a SV8. I think the equivalent is the Kampa Studland 8, but the Filey 6 was big enough for us.
Hope this helps

defintely. The Holkham has been re-branded (and had a minor facelift) this year as the Filey Classic, but you'll get more of a bargain by picking up a Holkham from a reputable Kampa dealer (ahem!).
Thanks all your advice has been brilliant and yes I agree although the Outwell Sun Valley has been a fantastic, spacious and sturdy tent, when very windy (and we do camp by the sea) it can wobble like a giant jelly, although this did keep one of our neighbours amused for hours one holiday as he watched from from his Outwell Montana. So keep watching ebay folks our lovely tent may soon be up for sale, she will be sadly missed but has served us very well.
