If, like me, anyone has bought one of the "technical" t-shirts for this year's challenge and has been disappointed with it, as it certainly isn't technical but just made of everyday, ordinary poly/cotton t-shirt material, I have been told that we can get our money back if we send it back to them.

I was disappointed too as I had specifically e-mailed to ask whether it contained cotton (which I hate) and have an e-mail reply stating it was polyester. I considered sending it back, but decided not to be difficult and at £15 it is not a vast sum, but I can't say I fancy wearing it as I would rather wear something I know is comfortable and will dry quickly.

I was never going to take it anyway.
I shall keep it for my personal use.
BUT... It sure as heck falls a long long way short of a Technical T shirt, which is a shame IMHO.

I specifically wanted a technical T-shirt. Mine has already gone back. Sad.
