I'm not a fan of the "Future Uniforms" that we see in the likes of "Endgame", to me they most look like "Pyjamas" and completely impractical, unless they are made out of some special "Nanoweave" that adapts based on temperature then its going to be pretty extreme in different climates, also the department colours make them look too "gimmicky"
I agree about the dislike of the future uniforms, more on the ground that they seemed designed solely to be worn by old people, out of how they were aging up the actors and for no other reason. The pants part just looks ridiculous - those things go up like half of the persons' torsos!
