Girls' UA Tech Big Logo Short Sleeve

UA Tech is our original go-to training gear: Under Armour men's Tech polos are loose, light, and keep you cool. Basically, they're built to be everything you need.

• Loose: Fuller cut for complete comfort.
• UA Tech fabric is quick-drying, ultra-soft & has a more natural feel
• Material wicks sweat & dries really fast
• Many UA Tech T's are made with recycled, traceable polyester & re-use about 5 bottles per shirt
