Worked perfectly for a long, cold run!
Color: (001) Black / Black / Reflective, Size: Medium
These worked perfectly! They aren’t the warmest but do the job for long cold runs in Texas. I ran a half marathon in 40 degree weather with these on and they kept me warm. They are a bit smaller in size, similar to what other reviewers have said. But I’m a small woman with small hands so the size medium I ordered were perfect. They were warm enough that I took them off at about mile 6. So overall, I’d definitely recommend for a light coverage, snug fit, glove.

Decent UA gloves pricey for the quality
Color: (001) Black / Black / Reflective, Size: Large
The thickness isn’t what I thought it would be. They’re ok for warmth as long as it isn’t single digits or in the negatives. They’re durable so far and grip is good. The size and fit are good for smaller to medium sized hands. It is also good for pressing your phone screen.

Great morning run gloves
Color: (001) Black / Black / Reflective, Size: Large
Absolutely love these gloves and they are perfect for a fall morning run or as an extra layer inside a mitten I have noticed under armour gloves seem to run slightly small but the large fit ne perfect and id consider my hand a little on the smaller side these fit perfectly snug
