Momentum Thermal Quarter Zip Shirt — Women's

On cool Southeast mornings, the Momentum Thermal is our go-to quarter zip for runners who want warmth without bulk. The thermal knit holds heat through early miles, while the quarter-zip neck lets you vent fast once the sun climbs. It layers cleanly under a shell when rain or wind rolls in.

• Thermal knit holds body heat on chilly starts without feeling heavy or restrictive
• Quarter-zip neckline opens quickly to dump heat when the temperature climbs mid-run
• Stretch construction moves with your stride and doesn't bind through the shoulders or arms
• Works as a base layer or mid layer, and slides easily under a light shell on wet or windy days
• Handles cool-morning runs, fall and winter training, and easy wear around town; Bone colorway in sizes S–XL
