Features & Benefits

  • Increased compression & freedom of movement - A combination of 2 unique fabrics offers horizontal stretch resistance providing intense muscular compression but still allows excellent freedom of movement through every stroke.
  • Support seams - Ultra sonically bonded seams have been specifically placed to improve the linkage of the body’s muscular kinetic chain, promoting better body positioning and increased muscularawareness.
  • Improved waistband - Microfibre and silicone strips guarantee a soft yet secure waistband. Anti-friction cord technology ensures the cord offers even tension and remains secure.
  • Construction - Improved finishes and components ensure a better fit, while its unique tape design guarantees you’ll stand out on the blocks.
  • Regular waist height - The regular waist jammer style offers greater flexibility and may be preferred by breast stroke and IM swimmers. However, waist height comes down to personal preference.
  • Composition: Upper – 65% Polyamide/35% Elastane. LOWER – 62% Polyamide/38% Elastane

Look good race well, good compression.
Sizing guide is rubbish - using the guide I should have ordered a 22 having read the reviews we ordered 24 but ended up with a 26
