Fit Notes — TYR Venzo, Avictor & Invictus Racing Jammer (Men's)
  • The TYR Venzo, Avictor and Invictus are elite competition racing jammers designed for a super tight, compressive, second-skin fit — they will feel extremely firm compared to a training jammer. This level of compression is intentional and is engineered for maximum performance during racing.
  • If you are between sizes, use your hip measurement as the primary guide — the jammer must seat correctly over the hips before the waistband can sit flat.
  • The suit should be completely wrinkle-free and smooth when correctly fitted, with all seams lying flat against the skin.
  • Allow 15–20 minutes to put on correctly for the first time. These suits are significantly tighter than standard racing jammers — take care with fingernails and do not rush the process.
  • Do not use petroleum-based products, oils, or sun cream before putting on the suit — these degrade the fabric's performance properties.
  • These are elite competition suits and are not designed for training use. Reserve exclusively for races and competition warm-ups to protect the suit's performance properties.
  • Rinse in cold fresh water immediately after every use. Do not machine wash, tumble dry, iron, or dry-clean.

Frequently Asked Questions — TYR Venzo, Avictor & Invictus Racing Jammer (Men's)

Take two body measurements — waist and hip — using a soft tape measure against your skin. Compare to the sizing table above. If your measurements fall between two sizes, use your hip measurement as the primary guide. Always use body measurements rather than your usual clothing size to find the correct fit.

TYR describes the Venzo, Avictor and Invictus as having a super tight, compressive fit for maximum performance and a second-skin feel. These are elite competition suits and are significantly tighter than standard racing jammers or training suits. They are designed for experienced competitive swimmers who are accustomed to high-compression racing suits. Allow 15–20 minutes to put the suit on correctly for the first time.

The Venzo, Avictor and Invictus share the same sizing chart and are all elite competition racing jammers from TYR's top-tier performance range. They differ in fabric technology, construction, and price point. Speak to a member of staff at Allens Swimwear for guidance on which suit is best suited to your level, event type, and budget.

TYR's elite racing jammers are designed for use in sanctioned competitive swimming events. Always check with your event organiser or governing body to confirm that the specific TYR jammer you have purchased is approved for the level of competition you are entering, as approval status can vary by product and event.

Competition racing jammers need to seat correctly over the hips before the waistband can sit flat. If the suit is too small in the hip, it will be extremely difficult to pull on and may cause discomfort or restrict movement during racing. TYR explicitly recommend using the hip measurement as the primary guide when between sizes on their competition suits.

These are elite competition suits and are not designed for regular training use. Using them for training will significantly reduce their lifespan and degrade the performance properties of the fabric. Reserve exclusively for races and competition warm-ups. TYR offer a range of training jammers designed for everyday pool use — speak to a member of staff at Allens for recommendations.

Allow at least 15–20 minutes to put on an elite competition racing jammer correctly for the first time. Work the suit up gradually from the ankles, smoothing out any wrinkles as you go. Take great care with fingernails — avoid pulling hard on the fabric. The suit should be completely wrinkle-free and smooth when correctly fitted. Do not use oils, sun cream, or petroleum-based products before putting on the suit.

Rinse the suit thoroughly in cold fresh water immediately after every use to remove chlorine and salt. Do not machine wash, tumble dry, iron, or dry-clean. Store flat and dry, away from direct sunlight. Avoid contact with sun cream, oils, or petroleum-based products as these degrade the fabric's performance properties. Careful handling after each use is essential to protect the suit's lifespan.
