The Men's 260 ZoneKnit™ Long Sleeve Half Zip Thermal Top by Icebreaker is a heavyweight base layer designed to regulate body temperature during high-intensity activities. Crafted from 100% pure merino wool, it offers natural breathability and odor resistance. The ZoneKnit™ construction features strategically placed panels of eyelet merino mesh to enhance ventilation where needed most. Additional features include raglan sleeves and gusseted underarms for improved mobility, thumb loops to keep sleeves in place and hands warm, a zipper chin guard to reduce friction, flatlock seams to prevent chafing, and a drop tail hem for added coverage. The slim fit ensures a snug, close-to-body fit suitable for low-bulk layering.
