Under Armour Boys Pennant 2.0 Pants - Warm, Breathable Track Pants

Our review of the Under Armour Boys' Pennant 2.0 Pants finds them best suited for active kids who need a warm layer that still breathes during sports and outdoor play. The single biggest reason to buy is the smooth tricot knit with a soft, brushed interior that traps warmth while the fabric wicks moisture and dries quickly - a practical combo for chilly practices and everyday wear. The pants balance comfort and function with an encased elastic waistband, external drawcord, and zip hand pockets for secure storage.

Key Features

• Smooth tricot knit: provides a durable outer face with a soft, brushed interior that helps retain warmth during cool mornings and evenings.
• Moisture-wicking material: pulls sweat away from the body and dries fast so kids stay comfortable during high-energy activities.
• Mesh knee panels: add targeted breathability behind the knees where heat and sweat concentrate during running or drills.
• Encased elastic waistband: with an external drawcord for a secure, adjustable fit that is easy for kids to use.
• Secure zip pockets: keep small items like a key or locker token safe during practice or recess.

Who It's For

These pants are ideal for boys who participate in team sports, track and field, or regular outdoor play and need a warm but breathable layer. The design suits school warm-ups, travel to practice, and casual wear when parents want something that handles sweat and dries quickly.

Kids who need a very slim, tapered fit or specialized compression performance should look elsewhere, as the Pennant 2.0 favors a loose, fuller cut for comfort rather than a tight athletic fit.

Pros
