T-shirt

Summary

Overview & Obtaining

T-shirts are one of two shirts available in RimWorld, and are inferior to the button-down shirt. T-shirts can be purchased from traders, crafted, or stripped from Outlanders and Pirates.

Crafting

As a complicated garment, t-shirts can only be made at tailoring benches, which requires complex clothing to be researched in order to be constructed. A t-shirt requires 40 of any textile, and 27 units of work.

Conclusion & Comparison

T-shirts are not particularly useful given that button-down shirts are a strict upgrade with only a minor increase in cost. Comparing the two options:

T-shirts have the same armor values, but don't cover the arms or neck
T-shirts offer slightly worse insulation from cold (22% vs. 26%)
T-shirts require fewer textiles to craft (40 vs. 45) and take less work (27 vs. 45)

In fact, the combination of a t-shirt and pants is actually worse than tribalwear. Compared to a t-shirt and pants:

Tribalwear offers identical armor and coverage
Tribalwear has better insulation - cold (55% vs. 42%)
Tribalwear has much better insulation - heat (55% vs. 18%)
Tribalwear requires fewer textiles to craft (60 vs. 80) and takes significantly less work (30 vs. 54)
