First, it's been a couple or three decades since I've been a youth member of BSA, so this is another old fogie opinion.
I am not as concerned about the cost of the uniform parts as their utility -- especially the pants. Nice olive-drab zip-off nylon pants with at least four front and two rear pockets would look just about the same as the current outdoor-unfriendly pants, and would be very useful in the outdoors.
I like the current khaki uniform shirt for indoor meetings and as a holder for patches, but wouldn't mind seeing an nylon official khaki outdoor shirt with big pockets and button-up sleeves (maybe with a silk-screened BSA logo on the breast, and smaller "outdoor" patches for patrol leaders, senior PLs, troop numbers and patrol identification??). I think it would defeat the utility of a nylon outdoor shirt to cover it in big patches like many a BSA "Chilean Admiral" shirt. Whether to use the official Field Outdoor Shirt would be up to individual units. On the other hand, I might be wrong, and it would not hurt a nylon camp shirt to sew patches all over it. Military guys sew patches on their uniforms and it doesn't seem to hurt them. Real outdoor use would be a good reason to go back to the smaller office patches of the past. (My sons laughed at my tiny SPL and PL patches in my old Boy Scout box. I just told them that we were real scouts and didn't need big patches to prove it ...

)
My own opinion would be to avoid camouflage patterns, as I really don't want Scouts looking like Marine LLRPs.
Does anyone really know if National is reconsidering the current uniform?
