Under Armour Women's Fly By Shorts
Product description
When workout shorts feel heavy or stay damp after you start moving, lightweight fabric and ventilation can make a noticeable difference. Under Armour's Women's Fly By Shorts pair a woven shell with mesh panels, sweat-wicking fabric, and a built-in brief. The regular fit is designed to sit between tight and loose, while a drawcord lets you adjust the ruched mid-rise waistband.
Where it shines

The appeal here is a practical mix of airflow and coverage. The woven fabric is described as lightweight and durable, and the mesh panels add ventilation in areas where extra breathability can help. Sweat-wicking material that dries quickly also suits workouts where you want shorts that do not feel damp for long, it does not, however, tell you how the fabric will feel in your specific conditions.


A built-in brief provides an extra layer of coverage without requiring separate shorts underneath. For example, if you're heading out for a run or warming up at the gym, the brief and internal drawcord mean you can pull on one pair and adjust the waist before you leave. The regular fit offers a middle ground: less close-fitting than compression-style shorts, but not intended to hang especially loose.

Quick overview
The main details are straightforward: women's shorts, lightweight woven fabric, breathable mesh panels, sweat-wicking and quick-drying material, a built-in brief, and a ruched mid-rise waistband with an internal drawcord. There are no listed inseam measurements, so shoppers who are particular about leg length may have to choose without that measurement.



That missing detail matters more if you are choosing between a shorter, freer-moving cut and a longer style with more leg coverage. If you prioritize ventilation and a built-in brief, these features point toward the Fly By Shorts, if you prefer a defined inseam or a more covered-up silhouette, look for a pair that lists its length clearly. Worth considering if your usual workout shorts feel stuffy or shift at the waist and you want an adjustable fit.
Best use cases

These are aimed at active use rather than dressing for warmth or coverage. The breathable panels and quick-drying fabric make them a reasonable fit for workouts or runs, while the built-in brief keeps the design self-contained. The drawcord is useful when you want to fine-tune the waistband before moving, but it is not a substitute for getting the overall size right.


It's not for you if exact inseam length is a deciding factor, or if you want a longer short with more leg coverage. The description gives no fabric blend, pocket details, or care instructions, either, so those preferences cannot be assessed from the available product information. Shoppers who mainly want an everyday, roomier short may prefer a cut built around that use instead.

Buying verdict

The Fly By Shorts make the most sense when your priorities are light fabric, ventilation, quick-drying performance, and a built-in brief. Their regular fit and adjustable waistband address comfort and fit in a simple way, without suggesting a compression feel or a deliberately oversized shape. The main tradeoff is uncertainty about length: there is no inseam information to help judge how much of the leg the shorts cover. Choose them if the listed performance features match your routine and you are comfortable with that unknown, pass if a specific short length or fuller coverage matters more than airflow.
