Dear Sirs,   
We want to buy Stretch PBT fabric to make race skin. 
Unlike a wetsuit the race/speed skin is breathable, so is 
more comfortable to worn all day on its own in warm 
conditions or as a snug thermal layer in cold conditions. 
The Speed skin is made from a stretch PBT fabric, which 
will not break down in high exposure to UV light or 
saltwater and is laminated to a micro porous windproof and 
breathable membrane. This is backed with a polypropylene 
fleece lining, which is lightweight and drys quickly.

So, the supplier of this fabric contact us urgently, 
Thanks. 
Regards,
