Frequently Asked Questions
Are buoyancy shorts allowed in triathlon races?
Buoyancy shorts are generally permitted in non-wetsuit swims and training, but rules vary by race and governing body. Always check the specific event rules before race day. They're most commonly used as a training tool rather than a race-day garment.
How do buoyancy shorts improve my swimming?
By lifting your hips and legs to a horizontal position, buoyancy shorts reduce drag and help you maintain better stroke mechanics. This is especially beneficial for triathletes who may have a less developed swim kick compared to pure swimmers.
What is Yamamoto neoprene?
Yamamoto 39 Cell neoprene is a premium Japanese material used in high-end wetsuits and buoyancy aids. It's lighter, more buoyant, and more flexible than standard neoprene — making it the gold standard for competitive swim and triathlon gear.
How do I choose the right size?
The 2XU Propel Buoyancy Short is available in XS through to XXL. We recommend referring to the 2XU size guide based on your waist measurement. The adjustable drawstring waist provides additional flexibility across sizes.
Does Swimwear Shack ship triathlon gear across Australia?
Yes — we ship Australia-wide from our Queensland base and also offer in-store pickup for local customers. Orders are dispatched promptly so you can get back in the water fast.
