This is difficult to answer in a meaningful way, as it is very subjective and context dependent. Quiet to one person is not quiet enough to another and vice versa. I’d say these are in the middle. Priority number 1 wasn’t to make the quietest pants, which means that these are not. But we certainly wanted to avoid a noisy pants if we could, and I think we did. You’ll find quieter pants and noisier pants.
But in terms of real world hunting use, I’m a bow hunter (compound) primarily. And I have stalked into multiple bucks under 60 yards, several times without the buck knowing I existed. And I’ve spent consecutive days within 100 yards of mature bucks, from sunrise to sunset and never felt like the pants were limiting my effectiveness or capability.
Sorry to disappoint, but these pants are NOT iPad compatible. And they don’t have knee pad pockets either.
