The Speedo Fastskin Cap belongs to the Speedo Fastskin Racing series. It is the first in the world to feature IQfit™ technology, which has been developed to meet the needs of swimmers as closely as possible. The innovative technology not only provides swimmers with improved performance, but also the comfort they need. The design of the cap was preceded by thorough scans of swimmers' heads, which were used to develop the cap to help the swimmer maximise the hydrodynamic effect and reduce overall drag in the water. Measurements have shown that the use of the Fastskin Cap reduces drag force by up to 3.4%.

Fastskin is a label for Speedo products that are designed for the best hydrodynamics in water. It's a swimming equipment designed for racing and performance swimmers to reach the most optimal performance. In the Speedo Fastskin range you will find complete equipment. The main ones are, of course, swimwear, goggles and caps that are homologated by FINA, but you can also find training equipment like kickboards, hand paddles and fins. The main success of these technologies is that Speedo carried out a 3D scan of elite swimmers and, through computer simulation, then conducted research and calculations on the resistance and durability of materials.
This swimming cap does not allow water into the cap so it protects your hair from being wet and especially from chlorine or salt water.

Approved and certified by the International Swimming Federation World Aquatics. It meets all international standards and allows start at prestigious races.
