Constructed for speed and comfort, this kneeskin emphasizes hydrodynamics without sacrificing mobility. The open-back design balances coverage with freedom of movement for shoulder rotation, key during starts and turns. Material technology focuses on reducing drag and allowing efficient water flow, which can help shorter sprint work as well as longer interval sets. Swimmers may benefit from a secure fit that remains comfortable through long sessions.
ARENA ST NEXT Men’s Racing Jammer
The ARENA ST NEXT Racing Jammer introduces lighter weight and enhanced durability with eco-friendly recycled fabrics. This model is the first FINA-approved racing suit in its class to leverage recycled yarns, combining performance with sustainability. The fabric mix aims to reduce water absorption and drag, contributing to swifter glide through the lane. The updated material supports longer-lasting compression, helping muscles stay engaged through repeated high-intensity efforts while reducing fatigue during competition.
Designed with a focus on endurance and speed, the ST NEXT jammer maintains a close, compressive fit that supports core stability without restricting hip mobility. The fabric’s density provides reliable muscle support, and the streamlined cut minimizes rough seams or irritation during dives, turns, and push-offs. Suitable for competition-ready routines and high-volume training, this jammer balances performance with environmental responsibility.
ARENA Solid Team MaxLife One Piece
The ARENA Solid Team MaxLife One Piece focuses on durability and performance for regular training and competition. Built with MaxLife Eco fabric, it provides excellent chlorine resistance and quick-drying properties, making it a practical choice for frequent swimmers. The design features an athletic back with broad straps, ensuring support and comfort along with a high-cut leg to maximize glide and range of motion during kicks and turns. It suits swimmers seeking longevity in a single piece with strong UV protection.
With an extended size range, this suit accommodates a broad spectrum of body types while maintaining a performance-focused silhouette. The fabric composition emphasizes long-lasting color, shape retention, and resistance to wear from chlorinated pools. Its front lining adds coverage and security for practice sessions, while the back coverage and strap configuration aim to minimize drag and support efficient water entry and exit.
ARENA ST NEXT Open Back Women’s Racing
The ARENA ST NEXT Open Back Women’s Racing suit marks a strong balance of recycled materials and performance compression. It provides a tight, race-ready fit designed to minimize drag while allowing shoulder mobility essential for efficient stroke mechanics. The recycled fabric blend reinforces sustainability without compromising durability or speed, making it a compelling option for swimmers focused on eco-friendly gear that still delivers competitive edge.
As a full-body, short-leg kneeskin variant, this suit emphasizes streamlined hydrodynamics and consistent compression across key muscle groups. The design supports powerful starts and stable leg drive through kicks, with an emphasis on reducing drag during transitions. Swimmers selecting this model typically belong to training squads or race teams that value a balance of affordability, performance, and environmental considerations.
ARENA Impulso Open Back Women’s Racing
The ARENA Impulso Open Back Women’s Racing suit is engineered for speed with high-quality woven fabric and a measured level of compression. The design emphasizes hydrodynamics with a hydrophobic treatment that reduces water absorption and drag. This balance of fabric durability and airflow helps swimmers maintain speed through the water and achieve efficient race positions. It also offers a robust, race-appropriate compression that supports major muscle groups while allowing comfortable shoulder movement for streamlined strokes.
As a World Aquatics-approved garment, the Impulso prioritizes a combination of speed, control, and long-lasting performance under competitive conditions. The open-back style pairs with a secure fit to minimize drag during starts, turns, and finishes. Swimmers selecting this model typically pursue mid-to-senior level competition, where consistent, repeatable performance across multiple events is essential.
Buying Guide
Fabric And Construction
Tech suits rely on specialized fabrics that deliver compression, reduced drag, and durable performance. Carbon-based materials, like those in the Air2 line, aim for a second-skin feel with minimal seams. Recycled fabric blends in ST Next models emphasize sustainability without sacrificing stretch or strength. MaxLife fabrics prioritize chlorine resistance and quick-drying performance, extending suit life in regular pool use. When evaluating suits, consider seam placement, one-piece versus multi-panel construction, and how the fabric interacts with your typical training pool conditions.
Fit, Sizing And Compression
Racing suits are designed to fit tightly to support powerful strokes and reduce drag. Proper sizing is critical: too loose may compromise compression and stability, while overly tight fits can impede breathing or arm movement. Review sizing charts for each model, and consider trying multiple sizes or consulting a team fitter. Compression should feel supportive without restricting shoulder rotation or hip mobility, especially during starts and turns where technique matters most.
Hydrodynamics And Drag Reduction
Hydrodynamic performance comes from fabric density, seam-free designs, and hydrophobic treatments. Open-back suits often prioritize greater shoulder range of motion, while kneeskin configurations optimize leg drive and lower body drag. The balance between drag reduction and freedom of movement varies by swimmer and stroke emphasis. Look for suits that maintain speed across both sprint and middle-distance events, and consider how your race strategy aligns with your suit’s design philosophy.
Durability And Chlorine Resistance
Chlorine exposure can degrade fabric over time, so durability is a practical consideration. MaxLife Eco fabric emphasizes long-lasting resistance to pool chemicals, while carbon-based suits may offer strong support with fewer seams. For frequent swimmers, a durable suit reduces replacement frequency and maintains performance through a training cycle. Always follow care guidelines to extend the life of the fabric and maintain fit integrity after repeated sessions.
Eco-Friendliness And Materials
Many newer suits incorporate recycled yarns or eco-friendly fabrics. Recycled-content options help reduce environmental impact while delivering race-ready performance. When comparing models, consider the proportion of recycled materials, the garment’s lifecycle, and any certifications related to sustainability. Eco-conscious choices can align performance goals with responsible manufacturing practices without compromising the core benefits of speed and compression.
Choosing By Swimmer Type
Swimmer type and event distance influence suit selection. Sprint specialists may favor tighter compression and higher hydrodynamic efficiency, while endurance-focused athletes might prioritize durability and quick-dry properties for longer meets. Age group and competition level also matter: juniors may require different sizing and support than adult athletes. Identify primary training routines, pool conditions, and your preferred stroke style to guide the final selection toward a suit that harmonizes fit, function, and long-term value.
