The perfect fit: mid-thigh swimsuit

If you hesitate between the total freedom of the brief and the coverage of the jammer, the square leg (or square cut) is exactly what you need. With its cut that stops at the top of the thigh, it offers a classic athletic look while completely freeing the knee for total freedom of movement. At Nation Sport, we do not select loose beach shorts that swell with water. Our square training swimsuits offer a slim, contoured fit that flattens water and eliminates drag. It's the perfect choice for the guy who wants style, comfort and efficiency in every beat.

A square cut that takes chlorine without flinching

No question of wearing a swimsuit that becomes loose and transparent after three visits to the municipal swimming pool. The brands available in our Boucherville warehouse — like Arena, Speedo and Finz — are chosen for their legendary robustness.

• Ultra-durable polyester threads: Designed with technological fabrics such as MaxLife or Endurance+, our square swimsuits resist the acid attack of chlorine. The fabric maintains its tension and opacity, even if you clock up the miles four times a week.

• Hydrodynamics and comfort: The square cut wraps the hips and upper thighs with light compression that supports the muscles without sagging them. Flat, soft seams eliminate the risk of irritation in the crotch during long sets.

• Complete your training setup: The square leg jersey is ideal for working on your turning technique. To maximize your workouts, consider taking a look at our nose clips (essential for backstroke runs) and our sturdy insulated water bottles to stay hydrated on the edge of the pool.

💡 Coach's Tip: Aligning the side seam With the square leg cut, the classic mistake that creates friction is poor positioning on the hips. When you put it on, make sure that the vertical side seam is perfectly straight on the side of your thigh, and that the jersey sits high enough on your hips. If it is positioned too low or crooked, the fabric will create horizontal folds on the front of the thigh every time you bend your leg for your kick. These folds collect water and break your slide. A tight and well-centered jersey is the key to a good time.
