Sizing & Fit Guide
Fit Profile: True to size based on aggregated Amazon customer reviews. The cut is designed for comfortable everyday wear with ease through the shoulders and body. If you are between sizes or prefer a roomier fit, consider sizing up. Always check the Amazon size chart for exact measurements.
How to Layer It
The beauty of a base layer this fine is that it disappears under everything you already wear. Slip the top beneath an oversized turtleneck sweater or a relaxed shirt on bitter mornings, and let the leggings sit smoothly under tailored trousers, jeans, or winter knitwear, with no bunching and no added bulk at the waist. Tucked into knee-high leather boots under a long coat, the whole effect stays sleek and refined while the warmth does its work quietly underneath.
Details & Care
Inside, an ultra-soft microfleece lining delivers the insulation, trapping core body heat while the four-way stretch poly-spandex blend moves with you and holds its tailored, second-skin shape through the day. Moisture-wicking technology helps prevent that clammy feeling when you move between cold streets and heated rooms. The fit reads true to size, so order your usual size for the intended close fit and always check the size chart before ordering. Follow the care guidance on the listing to keep the fleece soft, winter after winter.
