About this style
The Fly By shorts from Under Armour are an upgraded version of your favourite running staple, now featuring a convenient side zip pocket for small essentials. They're designed with a fitted, streamlined silhouette that comprises built-in compression shorts and a looser top layer. The lightweight woven fabric wicks sweat and dries quickly, while strategic mesh panels enhance ventilation. An updated ruched mid-rise waistband with an internal drawcord ensures a secure, personalised fit.

The fit is slightly large. I don't really like the fit for tennis However, I bought them because of the compression shorts and a place to keep my tennis balls. They are lightweith and slightly longer shorts which I prefer.

Great shorts fit perfect. Many other shorts are too short. These are the perfect. I am 5, 4 so they do not ride up

Solid option

The shorts are comfortable and breathable. One note- if you’re looking for spandex in shorts that are tighter (for longer runs etc.), these might not be the best choice. The spandex are looser, more comfortable for longer term wear, but can rise when moved for a while.

Not Great

No, I don't recommend this
Didn't love these. They look great online, but in person the outer shorts clung to the inner shorts and did not look very good.

Hey, Jill! Thank you for sharing your experience. We're sorry these shorts weren't a great fit. We'd love to get you in some different gear! Look out for an email from us soon.
Comfortable with no chafing
Originally posted on Under Armour
No, I don't recommend this
I bought these specifically for running to prevent chafing and it does a good job. However, I would have LOVED for it to have pockets on both sides. It has one pocket but it's way too small to really fit anything except for my key. Would be better with a bigger pocket!

Cool summer shorts

These shorts are very cool and great for running in the summer. Hoping they are as sturdy as my other under armour shorts.

Comfiest shorts ever!

I Have a really old pair of these that have held up for forever, the quality is great. I decided to get another pair in green, and was hoping it was the same feel and it is. My legs don’t chafe with these and I can wear them all day. The only difference between these is that my old ones had pockets and these don’t, but not a deal breaker for me.

Disappointing run
No, I don't recommend this
Had high hopes for these shorts but the underlayer is very thin and ride up as soon as I start running.

Great 2 in 1 shorts!

These 2 in 1 shorts look and feel great. Definitely worth the price! It would great if the exterior fabric didn't wrinkle when worn -- but that's a minor point.

This product is true to size. I am 5'2" 100lbs and the size small fit perfect. The blue color is so gorgeous that I ordered additional items in the same color. These are my go to shorts!
