Buy the retro ones, they never age and they are made of good material.
They shrink in the wash. Even on a cool wash my one shrunk.
I wouldn't mind Adidas making them provided it was trefoil/originals. Adidas are making kits for far too many nobodies like Stoke, West Ham etc. At least we have something unique.
For me, in order:
Umbro, Under Armor, Puma (provided it was an original template), don't care about the rest.
Have a feeling we will probably end up with something like Warrior once the current deal is up.
