ScentShield® S3® Mid-weight Wool Under Apparel. Cool, comfortable, and odor-resistant EFFECTIVE!

Made from 100% premium merino wool! Nothing compares with the comfort, resilience and wearability of wool. Unfortunately, it's also itchy... UNLESS you were to reduce the wool fibers to a super-fine diameter. Which happens to be exactly what ScentShield®'s done here.

The result? The softest, most comfortable wool you've ever felt, worthy of being right next to your skin. What's more, wool has its own odor-resistant properties. Combine that with special S3® antimicrobial treatment, and you've got reliable odor resistance in a comfortable, all-day-wearable garment. 

Features:
  • Super-fine, 18-micron merino wool... amazingly comfortable and resilient
  • S3 antimicrobial technology to aid in odor control
  • 4 Direction Stretch™ for a comfortable custom fit
  • Moisture-wicking so you stay dry
  • Flat-seam stitched for comfort.
Shirt:
  • Pullover-style with 1/4-zipper front
  • Vertical zippered chest pocket
  • Thumb loops for easy layering.
