Let's get straight to it — here's what actually matters on this one.

• Bamboo-derived viscose is notably soft and has some natural antibacterial properties, which can help reduce odor-related skin irritation.
• Cotton has a longer track record, is easier to verify for quality, and performs reliably across a wider range of climates.
• Bamboo fabric production varies widely in sustainability and chemical processing — check for certifications rather than assuming 'bamboo' means eco-friendly.
• For sensitive skin specifically, both perform well; the deciding factor is often breathability needs and how the specific fabric was processed.

The fit-and-fabric-health takeaway: The health benefit of bamboo fabric depends heavily on processing method — a reminder that fiber source alone doesn't guarantee fabric health.
