Frontier armor

"This stuff is lightweight and flexible from what I've read. Supposedly it can stop a blaster bolt."

- Bridger includes the armor on his wish list

Frontier armor was a type of gray colored armor available five years before the Battle of Yavin. The street urchin Ezra Bridger red that the armor was lightweight, flexible, and capable of withstanding a shot from a blaster. He included the armor on a wishlist he compiled in his journal.

Behind the scenes
Frontier armor was first shown in the reference book Star Wars Rebels: Rebel Journal by Ezra Bridger, which was written by Daniel Wallace and published in 2014.
