The Billabong Intruder 4/3 front zip is Billabong's entry-level full winter wetsuit with sealed front zip closure. An affordable option for those wanting the benefits of a front zip without paying mid-range prices.

Technology. Flexible 4/3 mm neoprene with GBS (Glued and Blind Stitched) sealed seams. Front zip with anti-flushing barrier to reduce water entry and give more freedom in shoulders and back. Lightweight construction focused on warmth-to-price ratio.

In the water. 4/3 mm is the standard Mallorca winter thickness (14-18 ºC between November and April). The front zip is appreciated on long sessions: less flushing, less weight at the end, loose shoulders for paddling or pumping. Works well for beginner and intermediate surfers on waves, SUP or wing.

For whom — how we see it at El Niño Mallorca. If you're moving up from a Launch back zip and want to try front zip without spending Revolution money, this Intruder is the logical choice. If you're unsure about sizing or want to compare it to the Revolution, reach out via WhatsApp or stop by the shop in Pollença.
