The Crewsaver Kortex is an entry level watersports helmet that is available in two sizes for the near perfect fit. This kayaking helmet is also suitable for other watersports such as Coasteering, gorge walking and dinghy Sailing. The Kortex helmet features an ABS outer shell for impact protection, this is then combined with a PU foam lining for additional comfort and shock absorption. The plastic shell also loops round the base of the ears for further impact protection on the side of the head. Whilst a number of ventilation holes make this cool to wear and also prevent a build-up of water when taking a dunking. The fit of the helmet is then easily trimmed and perfected by the internal ratchet system, whilst this is internal, it can be operated whilst on the head when it’s being worn.
