Collection: Jammers for Swimming

At Transition Zone you will find a wide selection of jammers – the popular swimwear used by swimmers and triathletes alike. Jammers are designed to give you maximum freedom of movement in the water while reducing drag and increasing your speed. We carry models from renowned brands such as Sailfish and Arena, known for their high quality and focus on performance. Whether you are training in the pool or swimming in open water, the right jammers can make a big difference to your comfort and efficiency.

Jammers are a type of swimwear that differs from traditional swimming trunks in that they have a longer leg length, typically from the hip to just above the knee. This longer length helps create a more hydrodynamic surface, reducing water resistance during swimming. The tight fit ensures that the fabric sits smoothly against the body without creating unnecessary turbulence, making jammers an obvious choice for competitive athletes who want to optimize their swim times. In addition, the material is often quick-drying and chlorine-resistant, making them both practical and durable.

An important reason for the popularity of jammers is the high level of comfort and support they provide during training and competition. Jammers are made of elastic and durable materials that both fit comfortably and provide a certain amount of compression to the muscles. The compression helps improve blood circulation and can thus reduce fatigue and increase recovery. At the same time, the tight-fitting design protects the muscles from unnecessary vibrations and injuries. The comfort makes it easier for swimmers and triathletes to focus on technique and performance without being distracted by discomfort.

We offer jammers from two of the market's leading brands: Sailfish and Arena. Sailfish is known for their focus on flexibility and freedom of movement, making their jammers suitable for both long training sessions and competitions, where comfort and functionality are essential. Arena has a long tradition in the swimming world and is constantly working on technological innovations to optimize hydrodynamics and fabric properties. Arena jammers are therefore often the first choice for elite athletes who want the last little percent of performance. At Transition Zone you can find different models and sizes from both brands, so you can always find the perfect pair of jammers for your level and needs.
