Dragonskin... it's been a long time. Pic rel is the shorthand full history of it. Basically it works fine as long as it's not conditioned and never exposed to substances that can dissolve the glue, like gasoline. An old-timer SME, Dr. Gary K. Roberts, tested a dragonskin panel many years ago and it stopped dozens of rifle rounds.

The disadvantages are threefold:
1. Cost. Even modern dragonskin is ludicrously expensive.
2. Weight. A full vest of SOV-3000 Level IV is about 40-45lb alone.
3. Durability, as mentioned above gasoline causes problems. 60% failure rate per army testing.
