Overview & Obtaining
Tribalwear is the only neolithic garment in RimWorld, and covers the torso and legs. Tribalwear requires 60 of any textile to make, less than the 85 required to make a button-down shirt and pants. As well as providing some insulation, tribalwear removes the 'Naked' thought debuff from colonists of both genders. Tribalwear can either be crafted or stripped from Tribal raiders.
As a neolithic garment, tribalwear can be constructed at a crafting spot, or tailoring bench - the former option not requiring any research whatsoever. A piece of tribalwear requires 60 of any textile, and 30 units of work.
Conclusion & Comparison
- Tribalwear has identical armor values, but less coverage (tribalwear doesn't cover the arms and neck)
- Tribalwear has better insulation from cold (55% vs. 46%)
- Tribalwear has much better insulation from heat (55% vs. 18%)
- Tribalwear has lower materials and work cost (60 textiles and 30 work vs. requires 85 textiles and 72 work)
A bit of extra neck and arm protection is usually seen as valuable enough to merit the lower insulation and higher crafting cost of pants and a button-down. But colonists in ultra-hot biomes may prefer the better insulation, especially when first starting out.
Tribalwear is ideal for prisoners, since it offers essential bodily coverage, it's cheap, and offers little protection. This makes prison breaks easier to deal with as prisoners can be downed easier (especially important through mid-late game when enemies frequently spawn with flak vests). You can force prisoners to wear tribalwear by stripping them before capturing, and then ensuring there's a stockpile of tribalwear in their cell/barracks.
Tribalwear offers a good amount of insulation from heat (55%), and a good amount of insulation from cold (55%). The exact insulation in-game depends on the textile used and the quality of the crafted item. Assuming normal quality, tribalwear offers:
