The Indomitus collection is inspired by the 2025 World Aquatics Championships venue, Singapore, also known as the “Lion City.” Indomitus , Latin for “untamable,” reflects the unstoppable spirit of the athletes, akin to the lion’s fearless desire to push boundaries and conquer any challenge.

A new era in competition swimwear has begun. The POWERSKIN Primo eliminates compromises by combining powerful compression and superior stretch in one physics-defying swimsuit. This high-compression swimsuit, approved World Aquatics , can be easily put on in less than 5 minutes - ideal for a race day routine. It is made of Arena Hyperforce™ stretch fabric and permanently hydrophobic TPU fibers for maximum water repellency.

It is worn by Olympic champion Kyle Chalmers, a sprint freestyle specialist and 100m freestyle gold medalist.
