Micro-Elite XT Zip-T Thermal Base Layer – Women's

Built for the coldest days on the mountain or in the backcountry, the Micro-Elite XT Zip-T is our top pick for women who need serious warmth without bulk. The thicker Chamois-weight Micro-Elite XT fabric traps more air than standard base layers, while the wind-resistant outer face cuts the bite. Bio-Silver antimicrobial treatment and a 1/4-zip neck keep you fresh and in control of your temperature all day.

• Heavyweight Micro-Elite XT fabric with maximum warmth rating (10/10) — traps significantly more air than standard base layer weights
• Wind-resistant outer face blocks ambient chill while the 4-way stretch construction lets you move freely through any terrain or activity
• Bio-Silver antimicrobial technology fights odor at the source, keeping this layer fresh through long days and multi-day trips
• 1/4-zip neck gives you fast, one-handed ventilation when your output picks up — no need to stop and strip layers
• Athletic body fit works as a true standalone heavy base layer or a low-profile mid-layer under a shell; available in Black/Grey
