La Cucaracha by Lalo Alcaraz for August 27, 2013

If it were a bullet-proof backpack on wheels with the telescopic handle, it’d still be hard to lug around (might dislocate a shoulder).

Compared to the old way of making bullet-resistant vests, yes. Compared to normal fabrics, no.

Another argument for putting school texts on Kindle!

Kevlar is a nylon, so no more nor less dense than any other fabrics. To make a “bulletproof” covering, though, you need many layers of the material, so it’s like wearing 10-20 shirts or pairs of pants, or in this case 10 backpacks inside one another.

To be more precise, I should have said that both Kevlar and nylon are polyamides, so their structure and gross properties are similar… Sorry for any confusion.

Are those the one’s with the Bulls Eye Pattern?
