Check Out the Warmest Tracksuit Bottoms by Nike

Fleece apparel is a cold-weather essential—and there's no shortage of Nike fleece joggers to get you through the winter. For a premium, polished look, go with a pair of Nike Tech Fleece bottoms.

These joggers are roomy in the thigh, but they feature a tapered design that narrows on the knee, offering a tailored look for everyday wear. The joggers feature tall, ribbed cuffs on the ankle and a zip pocket on the leg. Complete the look with a matching Nike Tech Fleece hoodie.

Club Fleece is the top-selling Nike fleece. The brushed-fleece fabric feels soft, smooth and cosy—and the fit of these joggers is roomy and relaxed. These joggers come with an elastic waistband and adjustable drawcord for a casual, customisable fit.

Some styles feature a loose, open hem on the bottom, while others feature elastic or ribbed cuffs on the ankle. If Nike Tech Fleece is made for a premium look, consider Club Fleece your trusted, cosy joggers to wear while lounging at home or to throw on for a quick errand.

Found in Nike jackets, sweatshirts, joggers and more, Nike Therma-FIT Technology is designed to manage the body's heat to help keep warm in cold conditions. You can find several types of tracksuit bottoms made with Nike Therma-FIT Technology, including high-performance training trousers made for tough workouts, cosy yoga trousers and everyday joggers.

Nike Forward joggers, which feature heat-regulating Nike Therma-FIT ADV Technology, are made with the newest Nike apparel innovation. Not a knit or a woven, Nike Forward material is made with ultra-thin, needle-punched layers of fibres, resulting in a lightweight material that provides year-round warmth.

Due to the use of recycled materials, lower energy use and lower material density, the first Nike Forward collection was made with an average of 75-percent less carbon output when compared with traditional knit fleece.

Nike Phoenix Fleece has a smooth feel on the outside and a brushed, cosy fleece on the inside, ideal for colder temperatures.

Made from a cotton-polyester blend and similar to the Club Fleece collection, Nike Phoenix Fleece features unique and elevated joggers styles, including high-waisted, oversized joggers, wide-leg styles and slim-fit, tailored cuts.

The tall, ribbed waistline of these joggers is designed to sit higher on the hips for a fit that will feel snug and stay put.

For the coldest of conditions, enter Nike All Conditions Gear (ACG). This line of footwear and apparel was created for braving the outdoor elements—and Nike ACG joggers and tracksuit bottoms are no exception.

Some styles, including the Nike ACG Polartec® 'Wolf Tree' Trousers for men and women, feature Polartec®, an ultra-soft and breathable fleece that helps hold in warm air while letting moisture escape, so sweat won't build up as the body gets warm.

To create these trousers, the design team found inspiration from Smith Rock, a rock-climbing playground in Central Oregon.

Bonus: these joggers are made from 100-percent recycled polyester fibres.
