Question is as the title says, **"Is there a way for a human barbarian to acquire the cold-honed half-elf racial trait?"**

Maybe through feats or traits? Something adopted?

(The racial trait is available from the books Bastards of Golarian and Heroes of the Fringe.)

EDIT: It doesn't have to exactly cold-honed, but instead just the ability to ignore snowy terrain and such.

> Snowborn can move through natural snow and ice at their normal speed and gain a +4 racial bonus on Fortitude saves to avoid nonlethal damage from cold environments.
