Jammers for men
Bridging the gap between the minimal coverage of a brief and the heavy drag of boardshorts, swim jammers have become the standard essential for competitive and fitness swimmers alike. offering a form-fitting cut that extends to just above the knee, jammers reduce water resistance while providing modest coverage. SwimOutlet stocks the world's largest selection of practice and racing jammers from industry giants like Speedo, TYR, Arena, Nike, and Sporti.
Practice vs. Racing: Choosing the Right Jammer
Not all jammers are built the same. The fabric you choose dictates how the suit performs.
-
Training Jammers (Durability): Designed for daily lap swimming. Look for descriptions like "Endurance," "Durafast," or 100% Polyester/PBT.
-
Why buy this? Polyester is 100% chlorine-proof. It creates a tough, durable suit that will not fade, stretch, or bag out, even after months of daily practice. These have zero compression and are meant for work.
-
-
Racing Jammers (Performance): Often called "Tech Suits." Look for Lycra, Spandex, or FINA-approved tags.
-
Why buy this? These use hydrophobic (water-repelling) fabrics and compression technology to squeeze muscles for better blood flow and speed.
-
Warning: Racing jammers are fragile. Chlorine eats Lycra/Spandex eventually, so save these specifically for swim meets, not practice.
-
The Fit Guide: How Tight Should It Be?
A swim jammer is aerodynamic equipment, not casual wear.
-
The Squeeze: A proper jammer should feel tight against the skin, specifically around the thigh opening and waist. If the fabric ripples or wrinkles, it is too big and will catch water (creating drag).
-
The Waistband: Unlike boardshorts, jammers feature a hidden internal drawstring. This is essential for keeping the suit secure during diving starts and flip turns.
Why Switch to a Jammer?
If you are transitioning from boardshorts to lap swimming, the difference is immediate.
-
Reduced Drag: Baggy shorts act like a parachute in the water. Jammers smooth your profile, instantly making your swimming easier and faster.
-
Modesty & Comfort: They offer the same thigh coverage as a standard short but without the chafing caused by wet, loose fabric rubbing against the legs.
-
Muscle Support: The snug fit provides mild compression to the quadriceps and hamstrings, reducing muscle oscillation (shaking) as you kick.
Can I wear jammers for water polo?
It is not recommended. In water polo, the extra fabric on the legs gives opponents something to grab. We recommend swim briefs or specialized water polo suits for that sport.
How do I make my jammer last longer?
Rinse your suit with cold, fresh water immediately after every swim to remove chlorine chemicals. Do not use a dryer—heat destroys the elastic fibers. Lay it flat to dry in the shade.
How do I size a jammer?
Most brands align with your pant waist size (e.g., Size 32 = 32-inch waist). However, if you are on the borderline between sizes, we recommend sizing down. Swimwear expands slightly when wet, and a loose jammer will slow you down.
