Frequently Asked Questions
Q: What is SCS hydrodynamic coating?
A: Super Composite Skin (SCS) is a hydrodynamic coating applied to the outer surface of the neoprene that reduces water resistance and surface drag. It allows water to flow more smoothly over the cap, helping you move faster through the water with less effort.
Q: Is the 2XU Propel Neoprene Swim Cap suitable for triathlon?
A: Yes — the Propel Neoprene Cap is designed for triathlon and open water swimming. The SCS coating reduces drag in the swim, the 3mm neoprene provides warmth in cold water, and the velcro chin strap keeps it securely in place through race starts and rough water.
Q: At what water temperature should I use a neoprene swim cap?
A: A neoprene swim cap is recommended when water temperatures drop below approximately 18°C. The 3mm neoprene in the Propel Cap provides meaningful insulation to prevent the disorienting "brain-freeze" effect that can occur in cold open water.
Q: What sizes is the 2XU Propel Neoprene Swim Cap available in?
A: Available at Swimwear Shack in S/M and L/XL in Black/Ambition.
