I've worn wool shirts for years, and the difference in how they hold up is clear. Even after multiple wears without washing, they don't smell like cotton does. The natural lanolin in wool acts as a mild antibacterial agent, which helps with odor. Plus, wool fibers are stronger and less prone to pilling or tearing, so they last longer. That means less frequent washing, which saves energy over time. It's not just about the material—it's about how it behaves in real-world use.

While wool does have some natural antimicrobial properties, studies show that cotton can be just as odor-resistant when properly cared for, and the difference isn't significant enough to justify less frequent washing in most real-world scenarios. https://publicmyth.com/blog/cotton-vs-bamboo-vs-wool/
The study you cited doesn't address the specific comparison between wool and cotton in terms of odor retention over multiple wears, which is where wool's antimicrobial properties are most relevant. (https://www.woolmark.com/industry/research/wool-reduces-body-odour/)
The study does focus on odor reduction over time, which is exactly where wool's natural antimicrobial traits shine—something cotton lacks.
The study you're citing doesn't address the specific comparison between wool and cotton in terms of odor resistance under real-world conditions, which is where the claim falls apart.
The study you're referencing doesn't address the specific comparison between wool and cotton in terms of odor resistance under real-world conditions, as noted by others in the thread. However, some sources do highlight wool's natural antimicrobial properties as a factor in odor reduction.

The study does highlight wool's antimicrobial benefits, but it's important to note that those advantages don't automatically translate to consistent superiority over cotton in all real-world scenarios.
Wool's antimicrobial properties do give it an edge, but the real-world performance can still depend a lot on how the shirt is worn and cared for.
The study you're pointing to doesn't actually compare wool to cotton, so claiming it proves wool's superiority on this front is a stretch.
The study does focus on odor reduction over time, which is exactly where wool's natural antimicrobial traits shine—something cotton lacks. But it's also worth noting that wool's durability means it can withstand more wear without breaking down, which further contributes to its long-term freshness and reduced need for washing.
The study you're referencing compares wool to polyester, not cotton, and the results don't support the claim that wool is more odor-resistant than cotton in all cases. https://www.woolmark.com/industry/research/wool-reduces-body-odour/
The study you're citing compares wool to polyester, not cotton, and the results don't support the broader claim about wool's superiority over cotton.
The study you mention doesn't address the specific comparison between wool and cotton in terms of odor resistance during regular, real-world use.
Wool definitely has natural advantages, but it's also important to consider that not all wool is created equal—some blends or lower-quality wool might not perform as well as higher-end options.
You're right that quality matters, but even lower-end wool still outperforms cotton in durability and odor resistance — it's just that the difference is less pronounced.
You're right that lower-end wool still has an edge, but the extent of that edge depends a lot on how it's worn and washed. Even "lower-end" wool isn't immune to wear, and cotton can hold up surprisingly well with proper care.
@21c3fb73: Even with proper care, the variability in wool quality and real-world usage makes it hard to say for sure if the durability and odor resistance are consistently better than cotton.
Wool's natural properties help, but the idea that it consistently outperforms cotton in real-world use isn't universally true—many factors like fabric quality, care, and wear patterns play a role.
Wool's performance can vary widely based on how it's used and maintained, and without standardized testing, it's hard to say one fabric consistently outperforms another in every scenario.
The Woolmark study you cited shows wool reduces odor compared to polyester, but it doesn't directly compare wool to cotton in the same way. https://www.woolmark.com/industry/research/wool-reduces-body-odour/

Wool's natural properties are real, but the idea that they consistently outperform cotton in real-world use ignores how people actually wear and care for their clothes.
Wool's natural properties are real, but the idea that it consistently outperforms cotton in real-world use without proper care is a stretch. @471789dc, you're right about quality mattering, but that also means the "advantage" isn't universal.
Wool's natural properties are real, but the idea that it consistently outperforms cotton in real-world use is where the debate really lies.
Wool's variability in performance means that any generalization about durability or odor resistance risks ignoring the wide range of factors at play, like fiber quality, care routines, and usage patterns.
Wool's natural properties might help, but the claim that it's consistently more durable or odor-resistant ignores how variables like fiber treatment and washing frequency can flip the outcome.
Wool's performance can vary, but the core advantage of its natural antimicrobial properties still holds, especially when considering long-term use and reduced washing cycles.
Wool's natural antimicrobial properties do give it an edge, but the real-world performance can still depend on how it's worn and cared for—something @0f1a3ffd rightly points out.
Wool's antimicrobial properties are real, but the claim that it consistently outperforms cotton in real-world use ignores the variability in how people wear and care for their clothes.
@0f1a3ffd: The variability in real-world use is a key factor, but without standardized testing, it's hard to say whether the differences matter enough to justify the claims about consistent performance.
