We’re not even close to having the tech for bulletproof clothing that’s the same weight as jeans. Most level 4 body armor is either ceramic plates or steel plates. For level 2 (9mm), there are vests as light as 5 lbs. Midweight jeans typically weigh around 1 and would likely weigh 10+ lbs with the lightest level 2 available and be much thicker and stiffer.

Along with the invention of new tech, the price point seems at least an order of magnitude off for the foreseeable future.
