Breachtrees are a plant native to Roshar used to make textiles.
Breachtrees produce a type of cotton. The cotton can be spun into fabric. The fabric is versatile, and can be used to make clothing ranging from coats to robes. It is likely also used to make shift dresses. The fabric, which sometimes has a scratchy feel, can be dyed.
Cultivation and Economy
Breachtrees are cultivated as a textile crop in Jah Keved and possibly in other parts of Roshar. The harvested cotton is traded as a commodity.
Kaladin had a padded brown breachtree coat as a young man.
In 1170, Brightlord Revilar forced Lin Davar to trade breachtree cotton and raw shum at an incredible discount to gain much-needed influence with Revilar.
Zahel wore a shabby tan breachtree cotton robe tied at his waist with a rope when he fought Kaladin in Urithiru.
