Bull-it Vectran Jeans – better than Kevlar!

The Bull-it jeans at Royal say nothing about having Vectran?

Royal Distributing. It's on page 88 in the Spring/Fall 2012 Catalog.

I'm under the impression that all of their jeans are Vectran, it might just be the difference between the LCP Super Fiber or just Vectran? Or is it all LCP Super Fiber?

From the website:

Bike jeans have followed the lead of a single brand over the last 10 years, short of Idea’s the industry has followed like sheep using the same materials they have no knowledge about, they assume its brand name will do the job you need if the day ever comes you’re skating on your backside down the tarmac.
After making jeans lined with those same fibres for 6 year we looked at it from a technical angle. For 2 years we have researched and tested fibres available to use as a single layer or a secondary liner in denim jeans to protect the rider.
Our ‘Super Fibre’ is a Liquid Crystal Polymer, it performs (according to Nasa) better than Kevlar for abrasion resistance, it’s key feature over all aramids though is it’s almost zero moisture retention, aramids decaying reasonably quickly when exposed to moisture, even humidity, so washing your Kevlar’s makes them weaker.
There are few high performance fibres that will do the job required in bike jeans, some use High Modulus Polyethylene (Brands like Dyneema or Spectra), these like aramids are not ideal for bike jeans, the high thermal conductivity in them passes the heat from the friction immediately to the skin, consequently burning the skin.
For the record, THERE IS NO SUCH THING AS ARMY GRADE KEVLAR, a selling feature used by some who have no idea. There is Para Aramid and Meta Aramid, Para having higher abrasion qualities and Meta having fire resistant qualities over Para. Balistic vest’s for example use multiple very thin layers of woven Para Kevlar, this acts as continuous and abrupt slowing of a bullet through each layer, if the same thickness of Kevlar was used in a single layer the bullet would penetrate the vest. This leads to the next issue…….
A question often asked on various blogs when looking at Kevlar jeans, Woven or Knitted? The guys that make both answer the question as it fits their argument, so for higher abrasion resistance the knitted has more density, simply apply what you know about a knitted jumper compared to a tightly woven one, this may help you see the picture, HOWEVER, the woven one will protect you better if you had a low speed and a sharp object directly penetrated the Kevlar, the tight weave in the woven offering resistance, the knitted having a more open appearance is likely to let the sharp object straight through to the skin.
Bull-it Jeans are made from or lined with a Covec Technical Textile, it was made for the purpose it was intended….Is there any other bike jeans product in the world today that can say the same thing? "
