About the Product
In deep winter, having a base layer that reacts to your body temperature is key. By using a combination of patented Polartec® fabrics, this base layer delivers supreme insulation and temperature regulation with high breathability and low fabric weight
Developed alongside elite riders, the Women’s Deep Winter Base Layer is built to perform through the coldest months of the year. Whether you're logging base miles or pushing hard through frosty mornings, this is your go-to foundation for warmth without excess weight.
Engineered with Polartec®’s most advanced fabric technologies, it combines targeted insulation and breathability to keep you comfortable as conditions change. Across the core and upper back, Polartec® Alpha™ provides active thermal regulation, keeping you warm without overheating during varied intensity rides.
Polartec® Power Grid™ is strategically placed along the arms and lower back. This innovative fabric features a geometric grid structure that traps heat close to the body while promoting airflow to wick moisture away efficiently.
The result? A lightweight yet powerful base layer that supports high-output winter training while maintaining a dry, comfortable feel throughout your ride.

Reviews
Deep winter women’s base layer
This is the best base layer I have ever owned so so very warm and the long tight neck is a godsend as all other neck warmers I’ve had are always too loose so this is fantastic. Thanks Lecol can’t wait for my new bib leggings to arrive too!
