7 Best Swim Trunks For Fishing Trips for Saltwater Use

Saltwater fishing demands gear that can handle the harsh combination of corrosive brine, relentless UV rays, and constant motion. The right pair of swim trunks isn’t just about comfort; it is a critical piece of equipment that protects you from the elements while you focus on the cast. Finding the perfect balance between mobility and durability is the secret to staying on the water from sunrise to sunset.

Saltwater Fishing: Key Features to Look For

When you are out on the open water, your gear faces a unique set of challenges that standard beachwear simply cannot handle. Look for fabrics with high-density weaves that resist snagging on hooks or boat hardware, as well as DWR (Durable Water Repellent) coatings to help the material shed water quickly. Quick-drying properties are non-negotiable, as sitting in damp, salt-crusted fabric will lead to severe chafing during a long day of casting.

Beyond the fabric, consider the utility of the pockets and the security of the closures. Saltwater is notoriously hard on zippers, so prioritize shorts with corrosion-resistant hardware or high-quality, non-corrosive plastics. A dedicated plier pocket or a reinforced loop for a line cutter can significantly improve your workflow when the bite is hot and every second counts.

Patagonia Baggies: Best for Rugged Durability

Patagonia Baggies are the gold standard for anglers who prioritize longevity over fancy features. Built with a heavy-duty nylon Supplex fabric, these shorts are nearly indestructible when navigating rocky shorelines or cluttered boat decks. They don’t have the bells and whistles of technical fishing gear, but their sheer toughness makes them a reliable choice for long-term use.

If you are the type of angler who values simplicity and wants a pair of shorts that will last for a decade, these are for you. They lack the specialized tool pockets found in modern technical gear, but their versatility makes them an excellent "do-everything" short. Choose these if your priority is a pair of shorts that can handle a rough day of bushwhacking to a remote saltwater flat.

Simms Superlight Shorts for All-Day Comfort

Simms understands the specific needs of the saltwater angler better than almost anyone else in the industry. The Superlight shorts are engineered with a focus on breathability and range of motion, featuring a fabric that moves with you rather than against you. They are exceptionally lightweight, which makes them a top contender for hot, humid days in the tropics.

These are the ideal choice for the dedicated fly angler who spends all day standing on a casting platform. While they are lighter and thinner than the Baggies, they still provide excellent protection against the sun. If you prefer a technical fit that feels like a second skin, the Simms Superlight is your best bet.

Howler Brothers Horizon: Best Hybrid Design

The Howler Brothers Horizon shorts bridge the gap between a technical fishing short and a casual piece of apparel you can wear to the post-trip dinner. They feature a sleek, modern aesthetic without sacrificing the functional details like a reinforced plier pocket and a comfortable, quick-dry interior. This hybrid approach makes them perfect for anglers who value style as much as performance.

These shorts are best suited for the angler who wants a "one-short" solution for their entire vacation. They are durable enough for the boat but refined enough for a casual restaurant. If you dislike the look of overly "techy" fishing gear, the Horizon provides the perfect middle ground.

Columbia PFG Backcast: Top Value for Anglers

The Columbia PFG (Performance Fishing Gear) line is a staple for a reason: it offers incredible performance at a price point that doesn’t break the bank. The Backcast shorts are lightweight, feature a mesh liner for comfort, and include an abundance of pockets to keep your small essentials organized. They are designed specifically for the humid, saltwater environment, and they perform admirably under pressure.

These are the best choice for the occasional angler or the beginner who wants reliable gear without a massive investment. You get a functional, purpose-built fishing short that handles saltwater exposure well. If you are looking for the most "bang for your buck" and don’t need high-end technical fabrics, look no further.

Pelagic Exo-Tech: Best for Sun Protection

When you are fishing in open saltwater, the sun reflecting off the water can be as intense as the direct rays from above. The Pelagic Exo-Tech shorts are designed with high-level UPF protection, acting as a shield for your skin during long hours of exposure. The fabric is also infused with stretch properties, ensuring that the shorts never restrict your movement while you are fighting a fish.

These are the right choice for anglers who spend their time in high-sun environments like the Florida Keys or the Bahamas. The focus here is strictly on performance and skin protection rather than casual wear. If you are prone to sunburn and need gear that keeps you protected, the Exo-Tech is a serious contender.

AFTCO Original Fishing Shorts for Utility

AFTCO has built its reputation on creating gear that can survive the rigors of commercial and tournament fishing. Their Original Fishing Shorts are famous for the "Guy Harvey" aesthetic and, more importantly, the heavy-duty Cordura nylon construction. They feature a specific pocket layout designed to hold a pair of pliers and a knife, keeping your essential tools within reach at all times.

These shorts are for the serious angler who needs their gear to function as a tool belt. They are heavier than other options on this list, which provides extra durability against sharp fish fins and gear. If you are constantly working on the deck of a boat and need maximum utility, these are the shorts for you.

Grundéns Breakwater: Best Saltwater Resilience

Grundéns is a brand deeply rooted in the commercial fishing industry, and that heritage shines through in their Breakwater shorts. These are built to withstand the most corrosive saltwater environments imaginable, utilizing a fabric that is highly resistant to salt buildup and staining. They are engineered to be tough, reliable, and incredibly low-maintenance.

If your fishing trips involve harsh, wet conditions where other shorts would fail, the Breakwater is your best insurance policy. They feel more robust than standard hiking shorts and are built to withstand heavy daily use. Choose these if you want a professional-grade short that won’t show wear after a week of intense saltwater action.

Selecting the Right Fabric for Moist Climates

In humid, saltwater environments, the biggest enemy of your gear is moisture retention. Fabrics that stay wet against your skin lead to "salt rash," a painful condition caused by salt crystals rubbing against the skin inside damp fabric. Always look for synthetic blends—specifically nylon and polyester—that are designed to wick moisture away from the body.

Avoid cotton or heavy canvas blends at all costs, as these will absorb water, become heavy, and stay wet for hours. A good rule of thumb is to look for a fabric weight that feels substantial but dries within 20 minutes when hung in the sun. The goal is to keep the material as dry as possible, which prevents both chafing and the buildup of odors.

Essential Care Tips for Saltwater Gear

The secret to making your fishing shorts last is a consistent post-trip cleaning routine. Salt is a crystalline structure that acts like sandpaper on your gear; if left to dry inside the fibers, it will degrade the fabric and ruin zippers over time. Always rinse your shorts thoroughly with fresh water immediately after leaving the boat or the beach.

Occasionally, use a mild, technical fabric wash to remove the salt and fish oils that accumulate over a long trip. Avoid using heavy fabric softeners, as these can clog the pores of the material and interfere with the quick-drying and moisture-wicking properties. By treating your gear with care, you ensure that it remains a reliable partner for your next trip to the water.

Choosing the right pair of swim trunks is a small detail that makes a massive difference in how much you enjoy your time on the water. Whether you prioritize rugged durability for the boat deck or lightweight comfort for the flats, there is a pair of shorts here that will serve you well. Now that you have the right gear, it is time to stop planning and get out there to make your next cast count.
