Micro-Elite Chamois Blocking Zip-T – Women's

For cold-weather training and layering days when you need serious warmth without bulk, this is our top pick for active women. Hot Chillys' Micro-Elite Chamois thermal blend manages moisture and holds heat well, while Bio-Silver antimicrobial tech keeps odor in check across back-to-back sessions. The deep quarter-zip and 4-way stretch let you move and vent without slowing down.

• Micro-Elite Chamois thermal blend rated Warmth Factor 8 — built for genuinely cold conditions, not just chilly mornings
• Bio-Silver antimicrobial technology controls odor through extended wear and repeated use without washing after every outing
• Deep quarter-zip neck for fast, on-the-move temperature regulation — open it up on climbs, zip it back on descents
• 4-way stretch construction moves with you; works equally well as a heavy base layer or a light mid-layer over a baselayer
• UPF 30 rated with an embossed color-block pattern — functional detail that doesn't look like standard base layer issue
