- • Best for: Frequent pool swimmers and training athletes needing long-lasting, performance-fit swimwear
- • Not ideal for: Users seeking full leg coverage or a looser, casual beach short

Longer-lasting fabric - with Lycra Xtra Life fibre
Lycra Xtra Life is engineered to resist chemical and mechanical degradation, delivering a lifespan that is five to ten times greater than ordinary spandex. The fibre maintains elasticity after repeated exposure to pool chemicals.
Fewer replacements are needed because the fabric keeps shape and stretch after regular chlorinated sessions. Swimmers who train often will see longer usable life from the briefs.
Secure training fit - with 9 Thread Flatlock Technology
Nine-thread flatlock seams mould to the body's contours and distribute tension across seams to reduce stress during vigorous movement. The construction minimises chafing while holding the shape under load.
A close, supportive fit stays in place during turns and dives, so frequent adjustments are less likely. The stitch pattern is suited to athletes who push through intense workouts.
Pool-ready performance - with chlorine, lotion and oil resistant finish
The material treatment resists fading, sagging and bagging caused by chlorine, while lotion and oil resistance prevents slippage from sunscreens or creams. Care instructions note the use of a specially formulated detergent to preserve those finishes.
Colours and fit hold up after repeated swims, keeping briefs reliable for regular users. The finish helps maintain coverage and appearance between washes.
