*In the Tech Back style suits we recommend wearing one size larger than you normally wear in arena training swimwear.

The arena One Tech Back is perfect for intensive and competitive swimmers. It's made from an extremely chlorine-resistant swim fabric that protects skin from the sun, is quick to dry, and is super durable. The open back in combination with the thin straps and high-cut leg provide maximum freedom of movement, excellent feel of water, and a flattering look.

Swim Tech Back Features:

• Thick upper-back straps provide superior support
• Contemporary cutout back style
• Full frontal lining provides additional comfort
• High leg cut ensures range of motion
• Maxlife fabric enhances durability

Performance Fabric:

• Made with MaxLife Eco, arena's most advanced fabric in a new sustainable version
• Maximum resistance to chlorinated water that resists fading, superior durability
• Quick drying, 50+ UV protective
• New Eco version made from 50% recycled polyester (from PET bottles), reducing CO2 and saving water
• Premium fabric made in Italy

Extended Youth Sizing: 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) of this training style. These smaller sizes are designed and sized with the smaller swimmer silhouette in mind. To ensure a proper fitting suit, please refer to the size charts for this style and take key body measurements.
