MANERA XTEND 4/3MM FRONT ZIP WETSUIT

Cold-water warmth. Unmatched flexibility. Built for winter sessions.

The MANERA XTEND 4/3mm is your cold-water performance suit - delivering the same lightweight feel and freedom of movement the XTEND is known for, now with added warmth for winter conditions. It’s designed for surfers who don’t want to sacrifice flexibility when the water drops.

Updated with OCENA® foam, this neoprene-free, bio-based material provides strong thermal insulation while reducing environmental impact. Inside, XTEND fleece traps heat without adding weight, while Squareflex jersey in high-mobility zones keeps the suit feeling fast and unrestricted through every paddle and turn.

Warm where you need it, flexible where it matters - this is winter performance without compromise.
