Plastic beneath your fingers: what your favourite climbing holds are really made of

If you’ve ever wondered why some holds feel like they were made just for you, while others surprise you in unexpected ways — the answer often lies in the material. In the world of modern sport climbing, three names dominate the conversation when it comes to manufacturing climbing holds and macro volumes: polyester, polyurethane, and polytalon.

These materials aren’t just chemical formulas — they shape how a hold feels, how it’s installed, how long it lasts, and what kind of climbing experience it offers. Let’s look at what makes each one special.

Polyester: precise shape and lasting structure

Polyester is one of the earliest materials used to make climbing holds. What sets it apart is its exceptional manufacturing precision and solid structure. Polyester holds feature crisp edges and consistent texture, making them perfect for routes that demand accuracy and refined technique.

Because of its durability and density, polyester is a great choice for indoor walls seeking long-lasting, sharply defined holds.

Polyurethane: flexibility for creative movement

Polyurethane is currently the most widely used material for climbing holds and macro volumes. Its biggest advantage lies in its combination of lightness and durability. It allows designers to create imaginative shapes, giving route setters the freedom to craft expressive, flowing climbs.

Macros made from polyurethane are easy to install and reposition, even frequently. Thanks to its elasticity and adjustable density, it’s a great choice for spaces of all sizes — from local gyms to major competition venues.

Polytalon: a new generation of precision

Polytalon is a next-generation material developed with input from both chemists and professional climbers. It stands out for its exceptional precision, uniform texture, and surface stability. Holds and macros made from polytalon are cast in high-precision silicone molds, resulting in high-detail consistency across batches.

Polytalon blends durability, comfort to the touch, and easy maintenance, making it ideal for professional-grade climbing facilities that demand top performance in every detail.

What about macros?

Macros are large shapes on the wall that influence movement, balance, and climbing rhythm. Their function isn’t just to be gripped — they’re there to be leaned on, smeared, mantled, and explored.

Due to their size and function, macro volumes are almost exclusively made of polyurethane or polytalon. Polyurethane offers a great balance of weight and resistance, while polytalon provides superior shape precision and surface stability, even in the largest dimensions.

Whether you’re a beginner getting to know the basics or an experienced competitor tackling complex lines, the material of the hold makes a big difference to your climbing experience.

Polyester gives clarity and durability, polyurethane brings creative freedom and versatility, while polytalon offers a new era of precision and visual refinement. Each has its own role — and each can help you discover something new about your technique, balance, and rhythm.
