Frequently Asked Questions
What sizes are available?
The Speedo Boys ECO Endurance+ Jammer is available in sizes 6 through to 16, covering a wide range of junior swimmers. Speedo sizing is based on Australian clothing sizes — if your child is between sizes, we recommend sizing up for comfort.
Is it suitable for competitive swimming?
Yes — the streamlined cut and low-drag design make it suitable for both training and competition. For elite race-day performance, a dedicated racing jammer may offer additional benefits, but the Endurance+ is a great all-rounder for club-level competition.
How long will it last in a chlorinated pool?
The ECO Endurance+ fabric is 100% chlorine resistant, meaning it retains its shape, colour, and elasticity far longer than standard swimwear. With proper care, it should last a full competitive season of regular training.
Does Swimwear Shack ship boys' swimwear across Australia?
Yes — we ship Australia-wide from our Queensland base. We also offer in-store pickup if you're local. Orders are dispatched quickly so your swimmer is ready for their next session.
How do I care for the jammer?
Rinse in cold fresh water after each use. Machine wash cold on a gentle cycle if needed. Do not tumble dry or leave in direct sunlight for extended periods — this preserves the fabric's elasticity and colour.
