You’ll see a few names for thin, lightweight sweatpants, and each hints at the fit or fabric.

• Lightweight joggers: Tapered legs with cuffed ankles, great for active wear.
• Track pants: Sporty, often straight-leg and breezy; sometimes feature side stripes.
• Mesh athletic pants: Airy knit for extra breathability and quick-dry comfort.
• Open-bottom sweatpants: Straight-leg hems that allow more airflow.
• Capri joggers: Cropped length for warm weather.
• Lounge pants: Relaxed, soft styles for downtime.

Use these terms when browsing to match the feel and function you’re after. Product pages usually clarify fabric, fit, and features.

Think about when and how you’ll wear them, then check features that match your needs.

• Workouts/running: Look for quick-dry synthetics, breathable mesh, and secure zip pockets.
• Loungewear: Soft cotton blends with a relaxed or wide-leg cut can feel cozy.
• Outdoor/hiking: Lightweight, water-resistant fabrics and zipper pockets help in changing conditions.
• Fit and cuffs: Joggers (cuffed) stay close to the ankle; open-bottom fits feel airier.
• Sizing: Check the size chart and customer reviews for rise, inseam, and overall fit notes.
• Care: Review washing instructions if you prefer easy-care fabrics.

Filters on Walmart.com can help you narrow by style, fabric, and features.

For warmer days, focus on breathable fabrics and looser cuts that promote airflow.

• Quick-dry synthetics: Lightweight polyester or nylon blends help manage sweat and dry faster.
• Mesh constructions: Eyelet or mesh panels increase ventilation.
• Cotton or cotton-linen blends: Naturally breathable options for casual wear.
• Looser silhouettes: Open-bottom, straight-leg, or wide-leg styles feel cooler than thick, cuffed fleece.
• Lighter colors: Light shades may feel cooler in direct sun than dark colors.
• Cropped options: Capri joggers offer extra airflow.

Pair with breathable tops and socks for comfort. Product details usually call out “lightweight,” “quick-dry,” or “mesh” when a style is summer-friendly.

Lightweight sweatpants use a range of fabrics, each with a different feel and function.

• Polyester/nylon: Often used for quick-dry, breathable, and sometimes water-resistant styles.
• Mesh knits: Airy construction that boosts ventilation for workouts and warm weather.
• Cotton blends: Cotton mixed with polyester (or linen) for softness with reduced bulk.
• Spandex/elastane: Added stretch for mobility and comfort, especially in joggers.

The exact blend can vary by item, so checking the fabric content on the product page is helpful. Care instructions differ by material, and following the label can help maintain comfort and shape over time.

The biggest differences are at the ankle and in overall shape.

• Joggers (cuffed): Tapered legs with elastic cuffs; they stay close to the ankle, which can be comfortable for running or training and offers a streamlined look.
• Open-bottom (straight-leg): Wider hem without a cuff; allows more airflow and easy on/off over shoes, often preferred for lounging, casual wear, or hiking.

Fit varies by style—some are slim, others relaxed. Check the size chart and reviews for notes on rise and inseam. On Walmart.com, you can filter by “joggers” or “open bottom” to quickly find your preferred leg opening.
