Flannel Pants for Women

Flannel pajama pants are typically crafted from soft, cozy fabrics—most often cotton flannel—that provide warmth without sacrificing breathability. At Old Navy, the relaxed fit and brushed feel make them a comfortable choice for lounging and everyday wear.

Think about fit, waistband style, and details like pockets or drawstrings—elastic waistbands offer easy comfort, while tapered legs and adjustable drawstrings help flatter your silhouette. Consider whether you want a solo pant, a matching set, or a plaid print to suit your personal style.

The soft flannel fabric is ideal for layering during colder months, keeping you cozy and warm all season long. In milder weather, they're breathable enough to wear on their own.

Flannel pants pair easily with a range of tops, from simple tees to oversized sweaters. For a cozy layered look, try a women's sweatshirt or hoodie or a soft cardigan to transition from indoor comfort to a quick coffee run.

Many styles feature functional pockets that add practicality for everyday wear. Old Navy also offers dedicated flannel pajama pants with pockets if that's a must-have feature for you.

Alongside individual pants, you'll find printed flannel pajama pant sets that pair coordinating tops and bottoms for an easy, put-together loungewear look. Explore more options in the full women's pajamas and sleepwear collection.

The soft flannel fabric is easy to care for and low-maintenance, making these pants a wardrobe staple you'll reach for again and again. Check the garment's care label for specific washing and drying instructions.

Beyond flannel, you can shop soft fleece women's sweatpants in joggers, wide-leg, and cropped styles, plus waffle-textured and poplin pajama pants for year-round comfort.

Their relaxed fit and elastic waistbands make them comfortable for snuggling on the couch, while a stylish plaid or printed design looks put-together enough for quick errands and casual outings.
