The alternate uniforms are where we'll see any substantive design changes if I'm reading things correctly. Those I'm looking forward to seeing, supposedly we'll have 2. I'm a traditionalist on these types of things but sometimes mixing it up can be fun if it's just a one off type deal. They look a bit flimsy and thin but maybe that's because they're using higher tech, lighter and tougher materials. I'm not too excited about the pattern masking in the numbers I've seen on some unis like the Seahawks new duds. That can be cool in artwork but for things like jerseys it just starts looking busy and eventually sloppy and disjointed. Plus I have no idea what the significance of the symbol they're using but it's also used as an art detail on other parts of the Uniforms. More unnecessary business.
The Skins look largely unchanged except for the cut and little details like Collars etc. One thing I'd like to see is a switch from the Mustard yellow to an actual gold for the pants, that Packer American Mustard yellow never did do it for me. using the actual gold tone from the 1962 or 1970 or '73 Uniforms would be sweet.
