The ST Next line represents ARENA’s sustainable approach to elite racing gear. This full-body one-piece is designed for a tight, compressive fit that supports streamlined movement through the water. The fabric blends recycled yarns to improve durability while keeping weight low, which helps reduce water absorption and drag. Swimmers may experience longer-lasting compression due to the fabric’s memory, contributing to consistent performance in multiple events. The open-back design balances support with freedom of movement, making it a strong choice for female sprinters prioritizing hydrodynamics and sustainability.

The Carbon Air2 kneeskin is part of Arena’s Carbon Series, designed to deliver a light, almost weightless sensation in the water. A single-piece construction reduces the number of seams, decreasing potential pressure points at the hips and encouraging a second-skin feel. Swimmers will appreciate easier on-and-off due to the streamlined design, which supports fast transitions between events. The fabric’s advanced memory helps maintain compression over time, contributing to stable performance across training and competition without sacrificing comfort.

The ST Next Classic builds on ARENA’s heritage with a sustainable twist. It combines elite race-grade technology with a one-piece silhouette designed to minimize water absorption and drag. The upgraded fabric, lighter by about 20% compared with prior iterations, contributes to faster movement through the water, while more than half of the fabric consists of recycled yarns. The result is durable compression that persists over time, helping athletes maintain optimal hydrostatic conditions and body alignment during sprints and longer freestyle efforts alike.

The Impulso jammer is tailored for younger athletes seeking pro-level performance. It uses a high-quality woven fabric that provides moderate compression to support muscle performance without restricting mobility. Hydrodynamic treatment minimizes water absorption and drag, helping swimmers achieve a longer, more efficient glide. The design emphasizes durability and resistance to stretching, ensuring the suit maintains its shape through training cycles and competitive events. This option offers a robust entry into top-tier racing equipment for junior swimmers.

Buying Guide: Key Considerations For Freestyle Tech Suits

  • Compression and fit: Race suits rely on tight compression to reduce drag and support muscle efficiency. Ensure the size chosen matches the swimmer’s measurements for the intended coverage (kneeskin, one-piece, or jammer).
  • Fabric science: Look for fabrics with low water absorption, high stretch memory, and sustainable fibers if environmental impact matters. Recycled yarn content can reflect both durability and eco-conscious design.
  • Seam construction: Fewer seams generally improve comfort and reduce drag. Kneeskin and one-piece designs often use seamless or bonded seams to minimize resistance.
  • Hydrodynamics: Patterns and fabric structure are engineered to streamline movement. Consider suits with proven scientific or tested hydrodynamic benefits for sprint and mid-distance events.
  • Size and race type: Women’s open-back, classic one-piece, and kneeskin options cater to different racing styles. For junior swimmers, a jammer provides appropriate coverage with performance benefits similar to adult tech suits.
  • Durability and care: Suits must endure repeated exposures to chlorinated water. Look for fabrics with strong memory and resistance to stretching; follow care instructions to maximize lifespan.
  • Sustainability: If environmental impact matters, prioritize suits with recycled materials and transparent production practices, while balancing the need for compression and performance.

When evaluating options, match the swimmer’s event profile with the suit’s construction. For sprinters, the strongest combination is a lightweight, low-drag fabric with high compression that maintains form across rapid strokes. For training blocks or longer freestyle sessions, durability and fabric memory become essential to preserve compression over time. In all cases, proper fit and the ability to put on and remove the suit without excessive effort contribute to consistent performance during warmups and racing.
