Bala'orasian Bugbear Shag

Bugbears' bodies are typically covered from head to toe with a layer of fur. This feature is designed to keep them warm. As a result, many bugbears wear little to no clothing.
However, the bugbears who reside in the Bala'orasian Bugbear Bureaucracy have taken this feature to a new level; they have undergone an insulation evolution.
Thousands of years ago, they chose to live in an area of Rodinia that they thought no one else would want to live in, the vast cold mountainous region to the north, far from the planet's equator. They thought correctly; they have inhabited this unforgiving environment for millennia and never once had to defend it from invaders. Who in their right mind would want to live in a frozen wasteland?
After navigating freezing mountains and tundras for so many centuries, the Bala'orasian bugbears have undergone a couple of minor evolutionary changes.
Firstly, the fur that covers their bodies became both twice as thick and twice as long, much like that of a yak. These features protect the bugbears from the punishingly low temperatures and high winds that Bala'oras is well known for.
Secondly, their skin began secreting oils that coat their fur, making it almost completely waterproof. This feature is critical for the bugbears' survival, because getting wet in such a cold, windy environment is tantamount to a death sentence.
These physiological adaptations have made the Bala'orasian bugbears ideally-suited to travelling through their cold and windy homeland. And since they don't require clothing, they can move around unencumbered, giving them yet another advantage over anyone else who might be unlucky enough to find themselves in such a region.  They are the ultimate outdoor warriors and survivalists; many of them become barbarians or rangers.
Who knows what genetic alterations their future holds in store for them? Increased intelligence? Increased range of darkvision?
