I have read about them actually. Because I bought their 'Carlos jacket' to be my golf waterproof, but I love the material so much I wear it for everything now.

They are similar to Under Armour but more recent really - as you say, a couple of sportsmen who weren't happy with the products on the market and looked into new materials to use and so on. I like the look of their golf stuff but I've not found it cheap enough anywhere to buy yet - I am never spending £60 on polos and £100 on trousers, that's for sure. The jacket was £82 but it is honestly nicer and lighter than any sporty rain jacket I've ever seen, so I think it was worth it. I'm on their mailing list in case they have a sale.
They only started sponsoring Fitzpatrick a few months back I think, imagine the high fives in their office when he won the USO. (They made Wolves kit last season too, assuming they still do. Oh, and Andy Murray too.)
