Under Armour Women's Fly By Shorts

When shorts feel clingy or take too long to dry, staying comfortable through a workout gets harder. The Under Armour Women's Fly By Shorts pair lightweight woven fabric with sweat-wicking, quick-drying construction to address those everyday annoyances.

A breathable mesh panel design adds ventilation, while a built-in brief provides coverage without needing a separate layer underneath.

The fit is described as regular—not especially snug or oversized—with a mid-rise waistband and an internal drawcord for adjustment.

What matters most

The main appeal is a combination of airflow, moisture management, and built-in coverage. The fabric is described as lightweight and durable, and it wicks sweat and dries quickly. That makes these shorts more purpose-built for moving and working up a sweat than a basic pair of woven shorts without those features.

Mesh panels are intended to improve ventilation, which may be welcome when a workout heats up. The built-in brief is another practical detail: it can simplify what you wear underneath, though anyone who prefers a fully lined or unlined feel may want to weigh that design against their usual preference.

The regular fit aims for a middle ground rather than a close compression-style feel. An internal drawcord lets you adjust the waist, and the ruched mid-rise waistband is designed with comfort in mind. From the way it is set up, these are straightforward active shorts rather than a highly specialized piece with many stated extras.

How to use it

These are suited to active days when light fabric and ventilation matter. For example, if you are heading out for a run or moving through a workout, the sweat-wicking fabric and mesh panels are designed to help manage heat and moisture. They can also work for everyday wear when you want athletic shorts with a built-in brief.

Keep in mind that the available details do not specify pockets, so do not count on them for carrying a phone or keys. If secure storage is a must for your routine, look for a pair whose pocket layout is clearly listed. The product details also do not describe a care routine, so follow the garment's own care label rather than assuming a particular washing method.

Practical tips

Think about how you like shorts to sit before choosing a size: this is a regular fit, not a tight or loose cut, and the internal drawcord offers some waist adjustment. The built-in brief is worth considering if you value coverage in one garment, if you prefer choosing your own base layer, that built-in construction may not match your preference.

For a quick change after exercise, the quick-drying claim is relevant, but it does not tell you exactly how fast the fabric dries in every condition. A solid pick if you want lightweight workout shorts with ventilation and an integrated brief. Not the best choice if pockets, a specific inseam, or a different lining setup are essential—those details are not provided here.

Practical doubts

Do these shorts have a built-in liner? Yes. The description identifies a built-in brief for added coverage.

Are they designed to fit tightly? They are described as a regular fit: neither too tight nor too loose. The internal drawcord allows waist adjustment.

Do they help with sweat and airflow? The fabric is described as sweat-wicking and quick-drying, and mesh panels are included for enhanced ventilation. Those features are intended to help during active use, though the details do not quantify performance.

When it makes sense

Choose the Fly By Shorts if you want a regular-fit athletic short with lightweight woven fabric, ventilation, and built-in coverage, and you do not need a stated pocket feature to make the purchase work. If you are comparing them with simpler unlined shorts, the integrated brief and mesh panels are the meaningful differences. If your decision depends on exact length, pocket placement, or a particular lining feel, the listed information leaves those points unanswered, so another clearly specified design may suit you better.
