Crop top et tank boxy : pourquoi c'est devenu l'uniforme de l'été fitness

Crop tops and boxy tank tops: why they've become the summer fitness uniform

This summer, it's impossible to go through a CrossFit box or an outdoor session without seeing a crop top or a boxy tank. It's not just a fashion statement: these two pieces meet a real need for performance. Here's why they've become so popular.

The crop top: freedom of movement and breathability

On a thruster, a pull-up, or a wall ball, every extra inch of fabric becomes a hindrance. The crop top frees up the waist, lets the stomach breathe, and, most importantly, doesn't ride up during overhead movements — unlike a classic t-shirt that rolls up with each repetition.

It's also a piece that allows the body to dissipate heat more efficiently, a real plus when temperatures rise. To delve deeper into training in hot weather: Training in CrossFit/Hyrox during a heatwave.

The boxy tank: the loose fit that never gets in the way

Wide cut, open armholes, relaxed drape: the boxy tank has become the go-to unisex piece for functional training sessions. It doesn't stick to sweat, allows total freedom for the shoulders — essential for Olympic movements and pull-ups — and can be worn equally well at the box or afterwards, when leaving the gym.

Why this duo works so well together

  • The mixed boxy tank: worn by both men and women, it becomes the common piece for group sessions.
  • The crop top as a complement: for women who want a more fitted piece under a tank top or for the hottest days.
  • Both in French terry or lightweight cotton: the material matters as much as the cut for staying comfortable during long sessions.
