What Our Gearhead(R) Experts Are Saying: "This piece is in my regular rotation for shoulder-season runs and cold-weather rides. It's warm but not bulky, and breathes well even during high output. I'll layer it over a base for training or wear it solo on milder days-it's super versatile." The GOREWEAR Training Thermo 1/4-Zip Jacket keeps us warm and dry when training conditions turn cold but we still want to push the pace. Designed as a versatile midlayer or standalone, it features breathable stretch fabric that insulates without overheating, and a soft brushed lining for next-to-skin comfort. Its lightweight build, athletic fit, and zip-neck ventilation make it easy to regulate temperature while moving fast. Thoughtful details like a reflective logo and drop-tail hem enhance performance in low-light and high-output conditions. Made with recycled content, the Training Thermo is as sustainable as it is dependable.
