## Questions & Answers

**Q: How does Thompson Tee stop sweat marks?**
A: Patented Hydro-Shield technology absorbs underarm sweat and blocks it from reaching your outer layers, preventing visible sweat marks and helping protect your clothes from stains.

**Q: Does Thompson Tee help with body odor?**
A: Yes. Hydro-Shield helps block underarm sweat and body odor from transferring to your outer layers, helping keep your clothes protected from both visible sweat marks and odor transfer.

**Q: Do the built-in sweat shields feel bulky?**
A: Thompson Tee's tailored sweat shield design and underarm seam help the structured material fold naturally with your arm, reducing bunching under clothing while keeping protection where you need it.

**Q: Does the sweat protection wash out?**
A: No. Hydro-Shield sweat protection is permanently built into the shirt and remains effective after many washes—no disposable pads, inserts or replacements required.

**Q: What's the difference between Original Fit and Slim Fit?**
A: Original fit offers a classic, relaxed undershirt fit in soft cotton. Slim fit sits closer to the body and uses a soft, breathable rayon blend with stretch for smooth, discreet layering. Both feature Hydro-Shield sweat and odor transfer protection.
