The Siren 3/3 or 4/3 Glued and Stitched model features a combination of our superior Japanese neoprene lined with Titanium Alpha 2.0 for the ultimate in warmth: Yamamoto MR7000 Superstretch in the arms, neck and shoulders giving you awesome flexibility where you need it, while the bottom half is constructed primarily with durable and hard working #38 titanium lined Yamamoto neoprene rubber.
Knee protection is covered with tough Armatek knee pads.

Specifically designed for a more functional fit, the Siren features a seam free underarm and a superstretch collar giving superb comfort around the neck and eliminating cold flushes.
  • Yamamoto Limestone Neoprene: Yamamoto Neoprene has a closed cell content of 94% — 23% higher than most competing neoprene materials — and with virtually no water absorption means the weight of this rubber remains nearly identical in wet or dry conditions, giving you more warmth than thicker wetsuits without the weight. It also dries more quickly than oil based neoprene wetsuits.
  • 40% MR 7000 Superstretch: Stretchy neoprene in the neck, arms and shoulders adds flexibility exactly where you need it.
  • 60% #38 Neoprene: Very durable neoprene in the torso and legs makes the Siren durable and long lasting.
  • Fully Titanium-lined: the entire suit is lined with a super thin heat retaining film called Titanium Alloy Alpha that reflects your bodyheat and also keeps out the cold. Every time you move, paddle, or expel energy, your thermal heat is reflected back to you—increasing heat retention by an amazing 40%.
  • No smoothie: a more durable and forgiving chest panel without loosing any warmth.
  • 3/3 Thickness: 3mm throughout the wetsuit
  • 4/3 Thickness: 3mm throughout the wetsuit with 4mm in the front and back chest panels
  • 4/3 Zirconium: 3mm throughout the wetsuit with 4mm Zirconium lining in the front and back chest panels, this is an extra warm option.
  • Glued & Double Blindstiched seams are sealed by a double coating of glue, butted together and then blindstitched on both sides of the seam.
  • Water-tight construction ensures no leaky seams, and is perfect for freezing temperatures.  
  • Zip Bib (ZB) neck entry closure system made from Titanium lined superstretch rubber creates a super warm seal and prevents leakage. A neck entry gives you the best flush-free seal through any duck-dive, and no chunky zip up the back gives extreme stretch throughout the back panel.
  • Armatek kneepads are a durable heat-pressed material designed to take the hardest of knocks.
  • Custom-Fit: Approximately 1/3 people don't fit a standard size, yet a correctly fitted wetsuit insulates and protects the wearer from cold water, wind and abrasion. We can Custom-Fit a Siren to your unique size and shape, just choose > CUSTOM as your size and complete our Custom-Fit form.
