I think NB have done well with kit designs, they have looked to the past and modernised them. As long as they have been signed with i don't think they have let us down with the kit design.
Although I do have a complain, and that is their training clothes for Liverpool. Like t shirts, hoodies and training pants have shitt quality.
I have bought 5-6 different things and they all have gone to hell.
I still use them at home, but I feel a premium hoodie should last longer then 6 months.
I did buy them from official Norwegian store, so pretty sure the items weren't fake.
