Men's Mk-1 Shorts by Under Armour - Lightweight 7in Inseam

In this review of the Men's Mk-1 Shorts by Under Armour, the bottom line is simple: these are best for active men who want a light, fast-drying short that moves with them. The reviewer found the shorts excel at practice, warmups, and casual post-game wear because the knit fabric is noticeably lightweight and the 4-way stretch lets you move without restriction. Construction focuses on breathability and quick moisture management, so the main reason to buy is consistent comfort during sweat-inducing activity.

Key Features

• Stretchy knit fabric: Feels featherlight against the skin so it does not weigh you down during workouts or long practice sessions.
• Fast-drying material: Wicks sweat away and dries quickly, keeping the wearer comfortable between drills or after a run.
• 4-way stretch: Fabric moves in every direction for unrestricted mobility during lateral cuts and high-knee movements.
• Mesh side panels: Add targeted ventilation to reduce overheating during intense activity.
• Encased elastic waistband: Internal drawcord provides an adjustable, secure fit without bulk.
• Open hand pockets: Offer quick storage for small essentials while keeping the shorts streamlined.

Who It's For

These shorts are aimed at men who train regularly and need a lightweight, breathable option for gym sessions, field practice, or warmups. The 7in inseam and stretch knit make them a good match for athletes who prefer a modern, athletic cut that still allows full range of motion.

Men seeking integrated liners, heavy-duty compression, or cargo-style storage should look elsewhere, as these have no liner and maintain a minimalist design focused on mobility and moisture control rather than structured support or large-capacity pockets.

Pros & Cons

Pros

• Very lightweight knit fabric that enhances comfort during extended wear.
• Material wicks sweat effectively and dries fast after heavy exertion.

• Simple waistband with internal drawcord creates a clean fit without bulk.

Cons

• No internal liner, so users wanting built-in compression or support will need a different style.
• Pocket depth is standard; not designed for secure storage of larger devices during intense activity.
