Keep comfortable and protected on long days in the field with the ScentBlocker NTS Long-Sleeve Shirt. Super-soft 100% polyester interlock fabric is treated with an S3 antimicrobial finish, which helps inhibit the growth of odor-causing bacteria. ScentBlocker's revolutionary Trinity scent control technology adsorbs up to 40% more human odors than activated carbon, so you stay fresher longer. The quarter-length front zipper extends through the top of the low-profile mock-neck collar for added protection against chilly air. Raglan sleeves, underarm gussets, and stretch panels in the elbows offer a full range of motion in the arms for even greater comfort. Thumbholes at the sleeve cuffs help keep hands warm and allow for easy layering. An angled chest pocket with secure zipper closure provides convenient storage for your smaller essentials. System Layer 1. Imported.
