Where to find blank grey jackets?

Where can I find a zip-up jacket (not a suit or tuxedo jacket btw) thats just plain grey with a hood? I would wear something like an LRG t-shirt under it, vans, and jeans, and possibly a grey hat too if it helps to imagine it? It doesn't matter the price (anything from $4-100), just one that kind of goes with an almost skater look. Any other brands besides LRG that feature this look?
