TYR Jammer 92% Polyester

For lap swimming, team practice, or race preparation, a jammer offers more leg coverage than a brief without the looser profile of a longer suit. The TYR Durafast Elite Solid Jammer pairs an above-the-knee cut with a close, compressive fit and a drawcord waist.

That combination favors a secure, streamlined feel over a relaxed one.

Best use cases

This suit is built around repeated pool sessions: laps, drills, turns, and practice where you want coverage that stays close to the body. The adjustable drawcord adds a way to secure the waist, while the above-the-knee cut covers more of the leg than a brief or square-leg suit. For example, during a practice set that moves from steady laps into turns and drills, the streamlined cut is intended to avoid the loose or baggy feel of a less fitted option.

It’s a great fit if you want a training-oriented jammer with more coverage than a brief and a close fit for swimming. It’s not for you if you prefer minimal leg coverage or a looser, less compressive feel. The listed details don’t include sizing guidance, so the fit you prefer may take more consideration than the fabric features alone suggest.

Product specs

The fabric is 92% polyester and 8% spandex. TYR describes its Durafast Elite fabric as using high-denier polyester fibers and circular-knit construction, with stretch for movement and a structured performance feel. The suit also has a drawcord waist and an above-the-knee cut.

The listed performance features include chlorine-proof, colorfast fabric, UPF 50+ sun protection, and an odor-control lining. These details make the suit relevant to frequent pool training and outdoor swimming, though the product information does not specify a care routine or how long its features last under any particular schedule. Without having tried it, the clearest basis for judging it is its stated fabric, fit, and intended use—not an assumption about how it will feel on every swimmer.

Where it shines

The main appeal is the combination of coverage and a streamlined cut. A brief leaves more of the leg exposed, a square-leg suit offers another shorter-cut approach. This jammer sits above the knee, making it the more covered option of those styles while keeping a close-to-body profile. The flexible construction is intended to support movement through strokes, turns, and drills rather than adding a loose silhouette.

What does that mean during a typical session? If you’re moving between laps and technique work, the drawcord and compressive fit are designed to keep the suit feeling secure, while the UPF 50+ rating is a useful listed feature for time in the sun. The chlorine-resistant and colorfast claims also speak to regular pool use, but they don’t establish a specific lifespan.

When it makes sense

Choose this TYR jammer if you want an above-the-knee training suit, value more leg coverage than a brief provides, and prefer a compressive fit with a waist drawcord. Its stated fabric blend and pool-focused features give you concrete reasons to consider it for practice or race preparation.

Look elsewhere if you want a relaxed fit, a shorter cut, or product details that spell out sizing and long-term wear expectations. The decision comes down less to a broad performance promise than to whether this particular cut and close fit match how you like to swim.
