I was worried they might be see-through in bright sunlight, but the shorts stay opaque even in the heat. And after two weeks, my thighs are visibly more toned and smoother. I highly recommend them!

      Frequently Asked Questions

      check_box

      Are the results immediate?

      The slimming effect is instantaneous (slimmer waist, reshaped curves). For visible effects on the skin and figure, most of our customers notice an improvement after a few weeks of regular use.

      check_box

      Are the leggings completely opaque?

      Absolutely. FitSlim has been designed to remain completely opaque, even during intense stretching or sports activities. There is no risk of transparency.

      check_box

      Do FitSlim leggings really help me burn more calories?

      Thanks to its active compression and innovative 3D fabric, FitSlim engages your muscles more with every step. The result: you naturally expend more energy, even without changing your habits.

      check_box

      Does FitSlim affect the appearance of cellulite?

      Yes. The 3D mesh stimulates blood circulation in targeted areas, which helps reduce the appearance of cellulite. At the same time, the shaping effect firms and tones the figure.

      check_box

      Can I machine wash the leggings?

      Of course. FitSlim can be machine washed at 30-40°C. We recommend avoiding bleach, tumble drying, and ironing to preserve the elasticity of the fabric.
