Speedo is what most Australian men learn to swim laps in, and this range is built for exactly that — pool swimming rather than the beach. Briefs are the largest part of it, with jammers and aquashorts covering the swimmers who want more coverage.

Brief, jammer or aquashort?

This is the question worth getting right, because the three cuts suit genuinely different swimmers.

Briefs — typically a 7cm side length — give the least drag and the most freedom at the hip. They're the traditional choice for lap swimming and racing, and they're what you'll see on most squad decks. If you swim seriously and don't mind the cut, a brief is the most efficient thing you can wear.

Jammers extend to just above the knee. They offer more coverage and a bit of compression through the thigh, and they've become the default for many adult swimmers who want performance without a brief. V-cut styles sit lower at the waist.

Aquashorts sit mid-thigh — shorter than a jammer, longer than a brief. They're a sensible middle ground for lap swimming, learn-to-swim instructing, or anyone who wants coverage without the full leg.

Why Endurance+ matters

Most of this range is built in Endurance+ or Eco Endurance+, which is 53% polyester and 47% PBT polyester with no elastane in it. Because chlorine attacks elastane specifically, removing it is what makes the fabric last. Speedo rates Endurance+ as 100% chlorine resistant and twenty times more fade resistant than conventional elastane swimwear, with four-way stretch. For anyone swimming three or more times a week, it's the single decision that most affects how long a pair lasts. Our swimwear fabrics guide compares it against Funky Trunks C-Infinity and Zoggs Ecolast.

Getting the size right

Speedo mens swimwear is sized by waist measurement rather than by clothing size, and Endurance+ should feel firm when new — it's polyester, so it won't relax into a comfortable fit the way an elastane blend does. Buy to your current waist measurement rather than sizing up. Our size charts cover Speedo alongside every brand we stock.

Common questions

What is the difference between swim briefs, jammers and aquashorts?
Briefs have the shortest cut, usually around 7cm at the side, and create the least drag — they're traditional for racing and lap swimming. Jammers extend to just above the knee and add coverage and mild compression. Aquashorts sit mid-thigh, between the two. All three work for training; the choice is about coverage preference rather than performance.

Is Speedo Endurance+ chlorine resistant?
Yes. Endurance+ is 53% polyester and 47% PBT polyester with no elastane content. Speedo rates it 100% chlorine resistant and twenty times more fade resistant than conventional elastane swimwear.

How long should mens training swimwear last?
An Endurance+ brief or jammer worn four to six times a week typically lasts a full season or longer if rinsed in cold water after every swim and dried flat in the shade. A conventional elastane-blend pair under the same load may start going baggy within two to three months.

Can I train in a racing jammer?
Not for long. Competition racesuits use bonded compressive fabric designed for a limited number of races and will break down quickly in daily training. Keep a racesuit for race day and train in Endurance+. See mens World Aquatics approved racesuits.
