Made for fun, speed, and confidence in the water, the arena Boys’ Design Swim Jammer is a reliable choice for young swimmers who spend plenty of time in the pool. Designed by arena, these stylish and durable jammers are ideal for both competitive juniors and regular swimmers who train or swim frequently. With a sporty look and performance-focused fit, they are perfect for lessons, club training, and race practice alike.

To begin with, these swim jammers are built to handle intensive use. The advanced MaxLife Eco fabric delivers maximum chlorine resistance, which helps the jammer retain its shape, colour, and fit over time. In addition, the fabric is extremely quick-drying and long-lasting, so it stays comfortable swim after swim. Because UPF 50+ UV protection is integrated directly into the material, it also provides added protection during outdoor swimming sessions.

Moreover, the streamlined jammer design supports speed and freedom of movement in the water. The 36 cm side length offers a comfortable, performance-oriented fit, while the soft front lining ensures reliable coverage and comfort. Meanwhile, the adjustable internal drawstring allows for a secure, customised fit. As a result, the jammer stays firmly in place during starts, turns, and longer training sessions, helping young swimmers focus on their technique and enjoyment.

Importantly, these swim jammers are also a more sustainable option. The eco-friendly MaxLife Eco fabric contains at least 50% recycled polyester sourced from PET bottles. Furthermore, the main fabric is certified by the Global Recycle Standard, which verifies recycled content and responsible social and environmental practices throughout the production chain.
