The Under Armour Gravel Ridge Dye swim trunks deliver serious performance through their integrated compression lining and high-tech fabric. I found the 5-inch inseam to be the perfect length for staying active without feeling restrictive, especially thanks to the 4-way stretch material that moves with you. These aren't just standard beach shorts. The UPF 50 protection and water-repellent finish make them a legitimate piece of technical gear for long days in the sun. The elastic waistband and drawstring ensure a secure fit, while the side and back pockets add practical storage for the essentials. Whether you are hitting the waves or lounging poolside, the quick-dry technology means you won't be stuck in heavy, soggy fabric for long.

Under Armour Men's Standard Compression Lined Volley shorts are a high-performance summer essential defined by their incredible mobility. I found the 4-way stretch fabric and the 7-inch inseam to be the perfect balance for transitioning from a morning surf to a casual afternoon lunch. The Black Sand Camo pattern looks sharp, but the real magic lies in the technical specs like the UPF 50 sun protection and the quick-dry, water-repellant finish. Having a built-in compression liner makes a massive difference in comfort, preventing the chafing often found in cheaper trunks. With functional side and back pockets and a secure drawstring waist, these feel like a premium piece of gear rather than just basic swimwear.

Under Armour has engineered a high-performance summer essential with these Black NEO Palm volley shorts that bridge the gap between active gear and casual beachwear. After testing the fit, the 4-way stretch fabric and 7-inch inseam provide a level of mobility that standard board shorts often lack, making them ideal for everything from swimming to beach volleyball. The water-repellent, quick-dry technology ensures you aren't bogged down by heavy, soaked fabric after a dip in the pool. I particularly like the inclusion of both side and back pockets for securing small essentials, alongside the UPF 50 protection for sun safety. With a secure drawstring and elastic waistband, these trunks stay comfortable through a full day of movement without feeling restrictive.

Buying Guide

A Guide to Selecting the Best Under Armour Men's Swimwear

A Guide to Selecting the Best Under Armour Men's Swimwear

Understanding Fabric Technology and Chlorine Resistance

The most critical factor in selecting Under Armour trunks is the composition of the fabric. Because these shorts are often intended for frequent use in pools, you must look for specialized synthetic blends designed for durability. High-quality performance trunks will feature enhanced chlorine resistance, which prevents the elastic fibers from breaking down and the fabric from becoming translucent or losing its shape over time. If you are primarily a recreational swimmer, a standard quick-dry polyester blend will suffice. However, if you are a competitive swimmer or a daily pool user, prioritize fabrics that explicitly mention shape retention and UV protection to ensure your investment lasts multiple seasons.

Inseam Length and Activity Level

The 'cut' of the trunk dictates both your range of motion and your aesthetic. Under Armour typically offers three primary lengths, and choosing the right one depends on your primary activity:

  • Short Inseam (2-3 inches): These are ideal for high-performance swimming and water sports where minimizing drag is essential. They provide maximum freedom of movement for the thighs but may feel too revealing for casual lounging.
  • Mid-Length (5-7 inches): This is the 'sweet spot' for versatility. These trunks offer enough coverage for beach volleyball or walking around a resort, while still being short enough to allow for active swimming.
  • Longer Inseam (7+ inches): Often categorized as board shorts, these are best suited for surfing or casual wear. They offer more protection against skin irritation from boards or sand but can feel heavy and restrictive when performing actual swimming laps.

Support Systems: Mesh Liners vs. Compression

One of the most significant decision points is how the trunks feel against your skin. Most Under Armour trunks come with an internal mesh liner designed to provide breathability and support. However, for athletes who experience significant chafing during long sessions in the water, you should look for models that incorporate a built-in compression liner. A compression liner acts much like athletic underwear, staying snug against the body to prevent skin-on-skin friction and providing a more secure, 'locked-in' feel that prevents the shorts from sagging when the fabric becomes waterlogged.

Key Features to Evaluate

Beyond the fabric and fit, pay close attention to the functional details that separate premium performance gear from basic swimwear. Look for drawstring integrity. A high-quality elastic waistband paired with a sturdy external drawstring is vital to ensure the shorts stay in place during dives or waves. Quick-dry capabilities are also paramount. Look for moisture-wicking technology that allows the fabric to shed water rapidly, preventing that heavy, uncomfortable feeling once you exit the pool. Finally, consider pocket utility. While deep pockets are great for beach days, ensure they are designed with drainage holes to prevent them from filling with water and weighing you down during activity.

Frequently Asked Questions

Quick answers about Under Armour Mens Swimwear before you buy.

While many models feature quick-drying fabrics, most Under Armour trunks are designed for leisure, training, and beach activities rather than high-performance competitive racing.

Most styles feature a standard athletic fit with an elastic waistband and internal drawcord, providing a secure feel that stays in place during movement.

Yes, many Under Armour swimwear options are built with UPF-rated fabrics to help protect your skin from harmful sun exposure during outdoor activities.

No, Under Armour typically utilizes high-quality synthetic blends that maintain their shape and resist sagging, even after prolonged exposure to water.

Many of their performance models are engineered to resist chlorine degradation, which helps maintain the fabric's elasticity and color over time.

Under Armour offers both. Board shorts are generally longer with a more structured waist, while swim trunks are often shorter and designed for versatile use from the pool to the beach.

To preserve the technical fabric and UV protection, it is best to rinse them in fresh water after use and avoid harsh detergents or heavy machine drying.
