Okay, so off the back of this thread I decided to buy the Nike kit as my first kit. Looking at the evidence it seems pretty likely that the FA is going to go over to Nike next season anyway so thought I'd get in there ahead of the game.
A friend of mine also gave me a Umbro Diamond shirt as he had put on a couple of pounds and was getting a new shirt at the end of the season anyway and for my first game I ended up wearing the Nike shorts and socks and, but actually wore the Umbro shirt as I much preferred it.
The Nike shorts and socks are seriously smart, the socks are completely plain black but have extra material around the arch and heel to make them better wearing and give some cushioning. The shorts are really smart, completely black (with a blacked-out embroidered Swoosh), 2 deep pockets on the side and a small square pocket at the back (i'd seen a couple of pictures of the shorts that suggested the rear pocket was in the middle with a zip, like their running shorts). They have no pattern in the material so look really good. I'm actually considering getting another pair for 'beach shorts' in the summer!
The top..................... unfortunately the top is a massive let down compared to the Umbro Diamond top. I actually don't mind the, much maligned, vertical zipped pocket but it's the material that I don't like. It's got an almost spotty pattern in the material, a bit like the 'technical' material that running vests are now made of and the fit isn't great either. It's quite baggy in the sleeves whereas I like the fitted look and feel of the Umbro sleeves.
I'm sure there will be an updated version before the start of next season but if I were Nike, I would leave the shorts and socks alone and concentrate on the shirt.
