Spidersilk jerkin

Spidersilk jerkins were types of mysterious light armor worn by drow kinslayers in the late 14 century DR.

Powers
Spidersilk jerkins were in reality made using drider silk, rather than silk from a regular giant spider. These armors were rare because of the dangers of procurement of the material, but the resulting light armor was as tough as a masterwork studded leather while it weighted almost nothing and showed no restrictions to the wearer's movements. As such, spellcasters could freely wear spidersilk jerkins without the armor restricting and interfering with their magic.

History
In the, spidersilk jerkins were worn by drow kinslayers who prowled the Neverwinter Wood in search of wood elves and other creatures to slaughter, led by priestesses of Lolth.
