Men's Project Rock Mesh Boxerjock Briefs, 5ft Inseam 2-Pack

In this review we look at the Under Armour Men's Project Rock Performance Tech Mesh Boxerjock Brief, 5' inseam, 2-pack to see who benefits most and why. The bottom line: these boxer briefs are best for active men who prioritize breathability and reliable support during workouts and long days. The allover mesh fabric and 4-way stretch move with the body and dramatically increase ventilation, which is the single biggest reason to buy for anyone who overheats in standard undershorts.

Key Features

• Allover mesh fabric: increases airflow for cooler, drier comfort during intense training or hot weather.
• 4-way stretch: allows unrestricted movement and helps the brief maintain shape through dynamic exercise.
• Performance waistband: sits flat and provides secure fit without digging in for everyday wear.
• Sweat-wicking & quick-dry: moves moisture away from skin so the underwear dries faster after workouts.
• No side or back seams: reduces chafing and improves comfort when worn for long shifts or long runs.
• Recycled fabric blend: made from 88% recycled polyester and 12% elastane circular knit for a balance of durability and stretch.

Who It's For

These boxerjock briefs are aimed at men who train regularly, jog, cycle, or work in warm environments and need underwear that breathes and supports. The 5' inseam keeps thighs covered without riding up, while the mesh construction suits sweaty sessions or daily active use.

Those who want a padded, compression-style short or prefer natural fibers only may want to look elsewhere; this pair emphasizes ventilation and synthetic performance materials rather than heavy insulation or pure cotton feel.

Pros & Cons

Pros

• Excellent ventilation from the allover mesh for hot conditions and sweaty workouts.
• Comfortable, supportive fit with no side or back seams to irritate skin.
• Durable construction and materials that hold up through repeated washing and wear.

Cons

• Some buyers report mixed impressions of sizing and value, so fit may require careful selection.
• The synthetic fabric may not match the feel of natural-fiber underwear for casual lounging.

Specifications
