The Powerskin ST 2.0 marks a new generation in a classic arena high performance racing suit. Three superior knitted fabrics have been combined to provide outstanding stretch, optimal compression, and total freedom of movement.

With a new ergonomic construction for enhanced core support, body lift, stability, and comfort, the suit helps swimmers keep optimum shape in the water. The extra reinforced shoulder strap enhances upper back comfort and durability, while the flatlock seams give the suit it’s “perfect fit” feel. The fabrics are chlorine resistant and provide protection against ultraviolet rays (50+ UPF).

Additional Sizing Info:
If your measurements are close to or exceed the upper size range available in our YOUTH sizes, we suggest that you also look at our smaller ADULT sizing (22-28). These smaller sizes are designed and sized with the smaller swimmer silhouette in mind.
