Squatproof Guarantee

At Next Extreme, we design our leggings and shorts for maximum performance. From heavy squats to intense Hyrox workouts — you need to focus on your training, not your outfit.

That’s why we stand behind our Squatproof Guarantee.


What does squatproof mean at Next Extreme?

Our leggings and shorts are developed and tested to be squatproof under:

  • the correct size choice

  • normal use during training

  • standard sports underwear

  • proper care according to washing instructions

This means the fabric does not become see-through during movements like squats, lunges, and lifts.


Still not squatproof? We’ll fix it.

Is your item still not squatproof with normal use and the correct size?

➡️ Then contact us within 30 days of receipt.
Our team carefully reviews your report and works with you to find a suitable solution, such as:

  • exchange

  • a store credit

  • or another suitable compensation


Important points to note

Squatproofness can be affected by factors beyond our control, such as:

  • a too small size (excessive stretch on the fabric)

  • light colors combined with dark or contrasting underwear

  • wear and tear from intensive or improper use

  • incorrect washing or drying (e.g., high temperatures)

To avoid disappointment, we always recommend:

  • stick to your usual size

  • when in doubt, choose between compression (smaller) or comfort (larger)
