Product Information

Full details

The SISSTR 7 Seas 5/4 Chest Zip Wetsuit is a high-performance choice for surfers tackling cold-water conditions between 44°F and 53°F (8°C - 12°C). Engineered with limestone-based neoprene and a specialized Thermal Fever Fiber lining, it offers a blend of exceptional warmth, flexibility, and sustainability, though its thickness means it is specifically intended for cooler climates rather than warm-water sessions.

FAQs

What is the ideal water temperature for this suit?

This wetsuit is designed for cold water conditions ranging from 44°F to 53°F (8°C - 12°C).

How should I clean my wetsuit?

Always rinse it with fresh cold water after use. If it becomes odorous, use a dedicated wetsuit shampoo, but never use harsh detergents or a washing machine.

Why is limestone neoprene better than standard neoprene?

Limestone-based neoprene is more environmentally friendly, lighter, and more durable, while offering better heat retention and elasticity.

Can I leave this suit in my car to dry?

It is not recommended. Heat and direct sunlight trapped in a car can cause the neoprene to degrade, delaminate, or lose its shape.

What does 5/4 mean?

The 5 refers to 5mm thick neoprene in the core/torso for maximum warmth, and the 4 refers to 4mm thick neoprene in the limbs to provide greater flexibility.

How do I store the suit for the off-season?

Store it clean, completely dry, and flat or on a wide-shouldered hanger in a cool, dark place.

Troubleshooting

Difficulty getting into the chest-zip entry

Ensure the neck gasket is fully stretched before pulling it over your head and use a 'bottom-up' approach, pulling the suit up to your waist completely before inserting your arms.

Water flushing into the neck area

Verify that the neck toggle is pulled tight and the chest panel is properly overlapped and smoothed down against the underlying barrier.

Pros and Cons

Pros

  • Excellent heat retention in cold water (44-53°F)
  • Dope-dyed eco-friendly fabric reduces environmental impact
  • Highly flexible material allows for unrestricted paddling
  • Rapid drying time due to advanced thermal lining
  • Durable seam construction minimizes cold water leaks

Cons

  • Too warm for use in tropical or mild water temperatures
  • Chest-zip entry may be more difficult to put on for some users
  • Requires careful hand-washing and maintenance to preserve lifespan

Setup, Compatibility & Care

To ensure the longevity of your wetsuit, always rinse it thoroughly with clean, fresh water after every session in the ocean to remove salt, sand, and debris. When drying, avoid direct sunlight, as UV rays can degrade the neoprene and cause the material to become brittle or lose its elasticity over time. Always hang your suit in a shaded, well-ventilated area, preferably folded over a wide hanger to prevent stretching the shoulder material. When entering or exiting the suit, be mindful of fingernails and sharp objects to avoid punctures in the high-stretch panels.
