Durability means the jammers keep shape and colour through frequent pool sessions and washes, reducing the need for frequent replacements.
Secure fit and freedom of movement - with streamlined cut and internal drawcord
A streamlined jammer silhouette reduces fabric bunching, while the stretch fabric permits a full range of motion. An internal drawcord allows waist adjustment for a snug fit.
Comfort during lessons and training is maintained, the trunks stay in place during turns and active drills.
Cleaner environmental footprint and faster turnaround - with 50% recycled materials and quick-dry finish
Half of the garment’s fibres are sourced from recycled materials, including a yarn made entirely from post-consumer waste such as plastic bottles. The quick-dry treatment speeds evaporation after use.
