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

In this review of the Under Armour Men's Mk-1 Shorts, the bottom line is simple: these shorts are for active men who want lightweight, breathable practice and warm-up wear that moves with them. The biggest reason to buy is the combination of stretchy 4-way knit fabric and fast-wicking performance that keeps the wearer cool and dry during high-output training or casual post-game wear. The review finds them comfortable for repeated use thanks to an encased elastic waistband with internal drawcord and practical open hand pockets.

Key Features

• Stretchy knit fabric: The lightweight knit material provides a comfortable, barely-there feel that reduces restriction during movement.
• Fast-wicking material: Fabric pulls moisture away from the skin and dries quickly so workouts stay comfortable even when sweating.
• 4-way stretch construction: The shorts move in every direction to support dynamic drills, sprints, and warm-ups without binding.
• Mesh side panels: Targeted ventilation at the sides improves breathability where heat builds up during effort.
• Encased waistband with drawcord: A secure fit is easy to dial in with the internal drawcord while the elastic keeps the shorts in place.
• Practical pockets: Open hand pockets offer quick storage for keys or a phone during warm-ups and after-practice routines.

Who It's For

These shorts suit men who train regularly and want a multiuse piece for practice, warm-ups, and casual wear after the game. Runners, gym-goers, and team-sport players will appreciate the 4-way stretch and fast-drying knit for unrestricted movement and quick moisture management.

They are not ideal for athletes who need built-in liners or compression support, or for those who want heavy insulation in cold-weather sessions. If you require a short with an inner liner or thermal protection, look elsewhere.

Pros & Cons

Pros

• Lightweight knit fabric feels comfortable and minimizes drag during activity.
• Material wicks sweat effectively and dries fast after intense sessions.
• Mesh side panels and 4-way stretch improve breathability and freedom of motion.
• Encased waistband with internal drawcord provides a secure, adjustable fit.

Cons

• No liner included, so these are not a substitute for shorts that provide built-in compression or modesty layers.
