Hmmm...not sure about Coolmax. Most of the ones I have purchased just say it's the "XYZ Chamois" and then describe how it fits. I would bet that the size is the problem, though. I had some Terry shorts that stretched out, and they KILLED me on a couple of rides before I figured out the problem.

It does look like TE will ship to the UK. They have international shipping rates listed and say they will ship to the US, UK and a couple of other places without additional identity verification.

Enjoy!
