The Billabong Intruder 4/3 boy is the junior/kids version of the Intruder winter suit: full 4/3 mm wetsuit in kids sizing, with the same entry-level philosophy as the adult range — reliable neoprene at reasonable price.

Technology. Flexible 4/3 mm neoprene in junior cut, with GBS (Glued and Blind Stitched) sealed seams and impact welded back zip with heat tape. Construction designed for kids and teens entering the water in winter or cold conditions.

In the water. 4/3 mm covers Mallorca winters (14-18 ºC) for lessons and surf sessions, SUP or sailing school in cold water. Kids generate less body heat than adults at the same activity level, so a 4/3 is recommended for real cold, even on short sessions.

For whom — how we see it at El Niño Mallorca. It's right for kids who are already initiated or who regularly enter the water in winter with school or family. For casual summer use a short 2/2 is plenty; but for real cold, this 4/3 is the pick. We'll confirm sizing by height/weight via WhatsApp or at the Pollença shop.
