Cloth meets Science

Yes, flysurfer has introduced the Lotus cloth. It is light, strong and supposedly you can not write with a marker on it. Flysurfer, that is not enough information! We want to know more!

So does Prof. Klemet Store who took the matter into his own hands and tested flysurfers three different materials in his advanced cloth lab. (Translate partially by google translate so don’t blame Klemet for the bad English)

“A small test of tear strength and abrasion resistance of standard, deluxe and Lotus.
It was relatively easy to tear the standard cloth and somewhat more difficult to tear the edge of deluxe. It was fun to see that the Lotus was not possible to tear even after several decent attempts. Only slightly deformed material in the Lotus.
Wear test was performed with wet steel wool with 200 rubs  on each piece of cloth. The 50 rubs with dry steel woll See image above for the results.

The Standard cloth seemed to wear fine, but had more spotty wear than deluxe. Deluxe had a smoother surface wear, but no major difference from standard. The lotus had the worst wear resistance.

I still think the tear strength is the most important for a typical speed-kiter, since the wear is minimal during normal use.  I’m most concerned about traumatic incidents like flying the kite into a tree rather than long term. The latter will probably be more relevant for kites used in kite courses. “
