Micro-Elite XT Zip-T Base Layer – Men's

Built for serious cold-weather output, the Micro-Elite XT Zip-T is our go-to heavyweight base layer for men who don't slow down when temperatures drop. The high-loft Micro-Elite XT fabric traps body heat aggressively, while the wind-resistant outer face adds a meaningful buffer without sacrificing the four-way stretch you need to move freely. Bio-Silver antimicrobial tech keeps odor from building up across long days in the field or on trail.

• Heavyweight Micro-Elite XT fabric with increased loft delivers maximum warmth — rated a 10 out of 10 on Hot Chillys' warmth scale
• Wind-resistant outer face blocks ambient chill without adding bulk or restricting movement
• Four-way stretch construction moves with you through technical terrain, layering systems, or pack straps
• 1/4-zip neck lets you dump heat fast on climbs and seal back up when you stop — no fussing with buttons or full zippers
• Bio-Silver antimicrobial technology embedded in the fabric controls odor through multi-day use without washing
