With the Tour rolling thru, I remembered the ban of the vortex suit a couple years ago.

This sparked my interest and I recently went down a rabbit hole looking at the different types of textiles different companies use on the sleeves of their trisuits. These fabrics when used around the sleeves created turbulence decreasing drag (am I getting this right?).

Most suits like bioracer, fusion, Huub, and many many others use the "striped" textile fabrics on the sleeves of their suits. Some only use it on the sleeves, while others like Roka also use it on the chest and back. Orca and Ryzon seem to have a honeycomb pattern. The honeycomb, which in enlarged pictures are actually fairly different from one another. From personal experience Kiwami also have different textile on the sleeves.

Of course there's more to it when it comes to a trisuit(comfort, support, pockets, etc) and the decision of picking one.

But Im assuming only a handful of mills make these specialty textiles, so any insider care to share who makes these textiles, what sort of R&D process goes into making them, and of course which are the best from various standards(aero, compression, hydrophobic)?
