Why choose it

These boxers are engineered for performance. The UA Tech™ fabric pulls moisture away from your skin, so you stay dry during intense training. Anti-odor technology prevents the growth of odor-causing microbes, keeping you fresh even after hours of wear. The 4-way stretch allows unrestricted movement in every direction, whether you’re squatting, sprinting, or sitting through a long meeting. The fitted cut provides support without feeling restrictive, and the no-fly design reduces chafing and bulk. Plus, the durable polyester blend holds its shape wash after wash.

Ideal use cases

• High-intensity training and gym sessions
• Running, hiking, and outdoor activities
• All-day wear at work or travel
• Layering under athletic or casual clothing

Good to know

Under Armour sizes run true to size; if between sizes, consider sizing up for a relaxed fit. The anti-odor treatment is permanent and won’t wash out. For best results, wash inside out in cold water and avoid fabric softeners to maintain moisture-wicking performance.
