Gear That Works Together

The UA MK-1 System Has What You Need for Any Training Situation

These days, there is specific kit for every type of fitness activity; running, spinning, cross training or HIIT. While Under Armour makes gear perfectly suited for each of those activities, sometimes athletes need a stylish variety that will work together to give you what you need in any training situation. Designed with Under Armour’s iconic stretch, mesh and sweat-wicking fabrics, the UA MK-1 collection styles athletes from head to toe, making one cohesive look no matter what they’re doing.


When I'm heading to the gym for a quick workout, the UA MK-1 collection is one of the first things I grab. With all of the options, there's an outfit for whatever I'm doing.

With simple colors and designs, each UA MK-1 piece layers to give athletes every advantage for any workout. Speed, agility, strength, cardio, in the gym, on the turf – no matter the workout or location, athletes can build their kit and get to work.


The popular UA MK-1 system just dropped new 2019 gear including long and short-sleeved shirts, pants, shorts, hoodies, full and half-zips, all available now on UA.com, at UA Brand Houses and at select retailers.
