What Are Cargo Shorts?

Once known as a go-to for men's casual wear, these pocket-heavy shorts have made their way into spring and summer wardrobes for both men and women. Known for their relaxed fit and signature side pockets, these shorts remain a go-to for laid-back style. So what exactly are cargo shorts—and why do so many people still love them?

What Are Considered Cargo Shorts?

Cargo shorts are knee-length shorts featuring large pockets on either side, typically near the thigh or knee area. These pockets are usually secured with Velcro flaps, buttons, or magnets. Also known as combat shorts, these wardrobe staples are loved for their unmatched comfort and practicality. Not only are cargo shorts easy to wear, but they also offer plenty of storage space, making it easy to carry everyday essentials without the need for a bag.

Cargo shorts are a great marriage of style and function, and a vital part of an active lifestyle. The best way to make your cargo shorts a stand-out fashion piece in your wardrobe is to pick the right ones that complement your unique personal style. Will you go for a longer pair of shorts with a relaxed fit, or a more classically vintage and clean-cut fit? Whatever you're looking for, the good news is that Unionbay cargo shorts come in an assortment of styles, cuts, and colors. That's a lot of choices! But don't worry—men's cargo shorts are a very versatile option that go well with plenty of casual wear ideas, so styling them is pretty hard to mess up.

A Short History

Cargo shorts are a breezy and comfortable fashion choice today, but they actually started as a functional piece of clothing. They evolved from the cargo pants used by the U.S. military in the 1940s during World War II. The reason behind their design is simple—in a warzone, you need all the pockets you can get! They were useful for storing supplies, ammunition, even the occasional cigarette.

Sometime in the 1980s, someone had the idea of shortening these cargo pants and marketing them to sports enthusiasts and fishermen. They were perfect for storing supplies while in the great outdoors, and were an instant hit. The 1990s saw the cargo short explode in popularity thanks to some hunky, half-naked models from some well-known clothing brands of the era. That caused the cross from function to fashion, and the shorts quickly became a hit with the male population. And thus started the cargo shorts' dominance over men’s fashion.

Cargo Shorts vs. Cargo Pants

In terms of use and flexibility, cargo shorts are king. They are much more versatile style-wise than your ordinary pair of shorts, easily pairing with any casual wear. Shirts, polo, sweaters—you name it, and a pair of cargo shorts will complete the look perfectly. They're also just crazy comfortable. Meanwhile, cargo pants are just as comfortable as their short counterparts, just maybe not as flexible. Certain cargo pants can also give the impression of a military uniform, rather than casual outdoor wear.

Are Cargo Shorts in Style?

Cargo shorts have become a wardrobe essential for women as well. While it’s rare for clothes to serve both a fashionable and practical purpose, a pair or cargo shorts checks both of these boxes, making them a must-have summer staple for men and women. Even as cargo shorts have been “taking it in the shorts" recently with declining sales, they're still wildly popular, especially during summer. It just goes to show the staying power of these pairs of shorts. 

The key to pulling off cargo shorts is getting the right fit.  Most of the fashion mishaps with these shorts are people wearing them two sizes too big.  However, if they fit right, cargo shorts can be fantastic and comfortable. Take our Alfie Twill Cargo Short, for example. It's a cargo-style short with the classic utility pockets that takes those utility pockets but combines them with a shorter and more fitted cut for a sleek and flattering fit. Or the Cordova Messenger Short, with a drawstring hem, making them even more versatile in a wardrobe! If larger pockets at knee height are trendier, then our Survivor Cargo Shorts are an ideal choice. 

Are Cargo Shorts Supposed to Be Baggy?

Men’s cargo shorts have long been the easy option for a weekend getaway, especially for their comfort and roomy pockets. Trends, however, are constantly changing. So, what are cargo shorts evolving into now? The original cargo shorts definition—ample pockets, durable cotton fabric, and a forgiving waist—still guides every pair. In other words, you still get to tap into the heritage of OG cargo shorts, meaning you still get the freedom to move and room for all of your essentials. But today’s cut flexes with fashion, streamlining the bulk and tapering the legs for a look that’s laid-back, not rumpled.

So, a classic loose fit is still great during outdoor activities like skating, hiking, or tackling weekend projects thanks to extra breathing room and perfect pairing with graphic tees. But what if you prefer sharper lines? That’s when you reach for modern cargo shorts with a tapered leg, nodding to chino shorts while keeping every pocket in play. Women can also cinch a high-rise waist for definition or slide into a boyfriend cut for laid-back confidence—both routes read effortlessly stylish.

Ultimately, the best fit balances comfort with purpose. Choose a pair that rests naturally at mid-waist, finishes just above the knee, and moves without excess fabric flapping. Whether you pick soft-washed cotton twill or a tech-stretch blend, UNIONBAY’s silhouettes merge functionality with polish, giving you a look that is easygoing, clean, and ready for anything.
