Under Armour Men's Performance Tech Trunk Boxer Briefs - Ultra-Soft

In this review of the Under Armour Men's Multi-Pack Performance Tech Trunk, the bottom line is simple: these trunks are best for active men who want an ultra-soft, breathable pair of undershorts that stay in place during workouts and daily wear. The single biggest reason to buy is the Performance Tech fabric, which is described as insanely soft and wicks sweat quickly, making these trunks practical for gym sessions, long work days and travel when comfort and moisture management matter most.

Key Features

• Ultra-soft Performance Tech: The lightweight fabric feels soft against skin and provides breathable comfort during extended wear.
• 4-way stretch construction: The material moves with the body in every direction so the trunks do not restrict motion during exercise.
• No-roll hem and chafe-free seams: The hem and seam design reduce irritation and help the trunks stay put under shorts or pants.
• Performance waistband with wordmark: The fitted waistband offers a secure fit and branded finish without digging in.
• Articulated mesh fly and gusset: Mesh panels increase airflow and add practical support where it matters most.

Who It's For

These trunks suit men who need comfortable active underwear for both gym use and everyday wear. The fitted, streamlined cut is ideal for those who want support without a too-tight feel and for anyone who prefers moisture-wicking, quick-dry fabric during workouts.

Those who prefer very heavy-duty or highly abrasion-resistant underwear, or who need an option with a longer inseam, may want to look elsewhere. Also, buyers sensitive to longevity concerns should consider that some customers reported durability variations after washing.

• Flexible 4-way stretch construction that follows movement without bunching.
