£34.95
A compressive, chlorine-resistant jammer from Orca built for regular pool and open water training.

Description
Orca Core Jammer: Built for the Pool, Ready for Open Water
The Core Jammer is Orca’s workhorse training jammer — a compressive, chlorine-resistant swimsuit designed for swimmers and triathletes who need reliable kit that holds up across regular sessions without requiring a premium budget to replace it frequently.
The Speedline PBT fabric is the key specification here. PBT (polybutylene terephthalate) is a swim-specific material chosen specifically for its chlorine resistance — it degrades far more slowly under pool chemical exposure than standard swimwear fabrics, which means the compressive properties, shape and fit are retained for significantly longer with appropriate post-swim care. For anyone training at volume, the durability difference over a season is noticeable.
Recycled Construction, No Performance Compromise
The Core Jammer is made with 80% recycled materials, independently verified to Global Recycled Standard (GRS) certification. The compressive fit delivers the support and streamlined profile that makes a jammer more effective in the water than loose-cut boardshort-style shorts — it sits close to the body, reduces drag, and stays in place whether you’re pushing off the wall or sighting in open water.
As with all compressive swimwear, Orca advise sizing up if you’re between sizes.
