Kneelength swimsuits, also known as kneeskins, are performance-focused swimwear designed for competitive swimmers who want the speed advantage of a racing suit with extended leg coverage. Sitting approximately 5cm above the knee, these suits provide enhanced muscle support, reduced drag, and improved body position in the water compared to traditional swimwear.
The category splits into two main types based on intended use. Racing kneelengths are built for competition performance, featuring technical fabrics like compression panels, water-repellent coatings, and streamlined construction. Most racing suits carry World Aquatics approval for official competition use. Training and recreational suits focus on durability and comfort, typically made from chlorine resistant fabrics that maintain their shape and performance through countless pool sessions.
Speedo dominates the racing category with their Fastskin LZR technology, offering everything from lightweight moderate compression suits to high-performance models with targeted compression zones. Arena brings innovative features like their new tensoelastic Hyperforce fabric and recycled material construction in their Powerskin range. For training and recreational swimming, AMANZI provides excellent value with their Armor Eco fabric offering superior chlorine resistance and all-day comfort.
Kneelength suits come in both open back and closed back configurations. Open back designs offer greater freedom of shoulder movement and are often preferred by swimmers with broader shoulders or those who prioritise stroke mobility. Closed back styles provide additional coverage and core support, which some swimmers find improves body position and may suit those with straighter back profiles.
For outdoor pool training common in Australia, look for UPF 50+ sun protection and quick-dry properties. Chlorine resistance ratings become crucial for regular pool use — fabrics with 5/5 ratings maintain their compression and colour far longer than basic materials. Racing suits typically prioritise hydrodynamic features over chlorine resistance, while training-focused suits reverse this priority for everyday durability.
The category serves women and girls primarily, with specialised junior racing ranges designed to give young competitive swimmers the same technological advantages as elite athletes while ensuring appropriate fit and comfort for developing bodies.
