Blackfish 3.5mm Long John

$429.99

Built with Andre Rerekura. Filmmaker. Waterman. Shipwreck Hunter.

The Blackfish 3.5mm Long John is built to pair with the Hooded Jacket or run on its own in warmer water as a standalone long john wetsuit.

Constructed from environmentally friendly limestone based neoprene with internal and external jerseys, bonded using Aqua Alpha water based glue. No solvents. No unnecessary chemicals.

The cut is built for underwater movement. Articulated knees allow natural finning. Fused ankles reduce water movement and hold shape over time. Self fabric finishes around neck and arm openings sit clean and comfortable session after session.

Features:

3.5mm limestone based neoprene, eco-friendly construction
Articulated knees for natural finning and freediving movement
Fused ankles to reduce water ingress and maintain shape
SIK silicone anti-abrasion dots on rear for reef and rock protection
Silicon print across the back reinforces durability in high wear zones
Triple glued, double blind stitched seams with internal taping and reinforced stress points
Side pocket with velcro for practical dive storage
Easy pull-on entry, no lube required

Designed to work as a complete spearfishing wetsuit system when layered with the Blackfish 3.5mm Hooded Jacket, or worn solo in warmer conditions.
