Grips designed specifically for smooth bars, which often make movements and skills like muscle-ups, chest-to-bar and toes-to-bar more difficult.

Thanks to the patented coating material, Zero ensures constant, immediate adherence to the bar, guaranteeing control and safety in every phase of the exercise.

ZERO CHALK | ZERO TRANSITION TIME | ZERO GRAVITY

Ideal for athletes of every level:

• Excellent in the learning phase, it supports you and helps you stay attached to the bar so you can focus on movement technique.
• Perfect for advanced athletes, it can boost your performance during a qualifier at the box with a clean bar and controlled conditions.

• Strap in polypropylene;
• Loop in acrylic and loop for wrist adjustment;
• Microfiber with a thickness of 1.8 mm coated with a layer of patented rubberized polymer with a thickness of 1.2 mm
• Total thickness 3.00 mm

For cleaning the outer surface, we recommend using a standard degreaser.

Hand washing is recommended to avoid damaging the materials used.

Do not dry the product in direct sunlight after washing.

The ZERO callus guard provides excellent grip on standard and smooth bars.

• We do not recommend using it on rough bars.
• This product must be used strictly WITHOUT CHALK.

Product designed and made entirely in Italy.

Handcrafted.

We use materials tested and approved by some of the best European athletes.

Note: Since this is a handmade product, slight color variations may occur between different sizes or even within the same pair.
Color differences do not affect performance in any way.

There is no two-year warranty for this type of product; callus guards are considered a “perishable good.” Wear depends on many factors: the type of bars they’re used on, how they’re used, the user’s weight and their approach to the bar, which can affect impact and therefore wear, as well as training intensity and volume.

We recommend always checking the condition of the callus guards and replacing them if necessary—after 4–6 months, a year, or whenever you feel it’s needed—to always work safely on bars and rings and ensure optimal performance. For any issues, please contact us at customercare@stmnfitness.com
