Under Armour Men's Multi-Pack Performance Tech Trunk - Ultra-Soft

In this review of the Performance Tech Trunk, the bottom line is simple: these boxer briefs are best for active men who want a soft, breathable pair for gym days and long work shifts. The pack stands out for its insanely soft Performance Tech fabric that wicks sweat and dries quickly, making it a reliable everyday option. Fit is streamlined and supportive without being constricting, and tagless construction plus chafe-free seams keep them comfortable during movement.

Key Features

• Ultra-soft Performance Tech fabric: Feels smooth against skin and provides reliable moisture wicking for sweat-heavy activities.
• 4-way stretch construction: Moves with the body for exercises or daily wear so the trunks do not restrict motion.
• No-roll hem: Keeps the leg opening in place during runs or squats to reduce annoying bunching.
• Chafe-free seams and tagless design: Eliminates irritation for long wear under pants or shorts.
• Articulated mesh fly panel and gusset: Adds breathability and targeted ventilation where it matters most.
• Performance waistband with wordmark: Provides a secure feel without digging in.

Who It's For

These trunks are ideal for men who regularly work out, commute, or spend long days on their feet and need underwear that stays comfortable and breathable. The fitted, streamlined cut offers good support for gym sessions while remaining comfortable under business or casual pants.

Men who prioritize extreme durability or prefer very loose boxer styles should look elsewhere; some customers report mixed experiences with longevity and occasional fabric issues after washing, so those who need lifetime wear from a single pair may prefer reinforced or heavier-weight options.

Pros & Cons

Pros

• Very comfortable, soft fabric that breathes and wicks moisture effectively.
• Supportive, fitted cut that works well for both workouts and everyday wear.
• Thoughtful construction like no side or back seams and a no-roll hem reduces irritation.

Cons

• Durability is mixed for some users, with a few reports of fabric wearing or tearing after washing.
• The fitted style may feel snug to those who prefer a loose boxer fit.

Our Verdict
