The remarkably soft wool of an alpaca. It is warm, protects well from heat, and fetches a high price.
Alpaca wool is acquired by shearing tamed alpacas - each alpaca can be sheared every 10 days for 45 wool, for an average of 4.5 per day.
It can also be purchased from traders.
Alpaca wool has the second worst protective stats of any textile in the game, tied only with other wools, and besting cloth only by virtue of proving significantly more heat armor (though still little relative to textiles like devilstrand). Like other wools, however, where alpaca wool excels is in cold insulation. It offers the 4th best cold insulation of any textile in the game. For comparison, its heat insulation is lacking, tied for 10th of all textiles, comparable to many leathers.
Thus, it is almost entirely irrelevant as protective clothing. Additionally, its mediocre heat insulation make it unattractive in hot biomes, as many leathers are available with equivalent insulation but significantly better protection. While its cold insulation may prove useful in colder biomes, many less insulative materials may be utilized instead for their higher protective values. Where alpaca wool clothing shines is its ease of acquisition; the alpaca has the second fastest Per Day production rate for wool while only eating as much as a sheep. This means it can be useful for parkas or other pieces of clothing which are situational.
For use in furniture, it only has a somewhat improved beauty factor over other common textiles, but its rapid redundancy as clothing, the ease of acquisition, and modest value makes it a solid choice for improving furniture beauty and providing bulk textiles for construction. Care should be taken however as, like other wools in RimWorld, it is exceptionally flammable.
