Understanding Neoprene: The Key Material for Spearfishing Wetsuits

Several factors play an important role in choosing the right wetsuit for spearfishing.

Seasonality Considerations

Seasonality is a significant factor: for spearfishing in the Mediterranean Sea (or generally in warm waters), a versatile 5 mm wetsuit is recommended, suitable for use between March–April and October–November.

Additionally, there are wetsuits ideal for warm waters worldwide and during summer in the Mediterranean.

Finally, wetsuits of 7 mm or thicker are suitable for colder waters (for winter use).

Material Composition

Spearfishing wetsuits are distinguished by their construction: they are usually “sandwiched,” made of a neoprene layer and an outer fabric layer (jersey or lycra). This extra fabric layer improves comfort. Lycra is known for softness and flexibility, while jersey offers better resistance to cuts and abrasions.

These wetsuits are extremely rugged, so it is necessary to use soapy water for easier dressing.

Additional Features

There are two manufacturing processes for wetsuits:

• Chicle: Smooth on the outside with a sandwiched interior (all assembled with adhesive).
• Sandwich: As the name suggests, it includes a fabric layer between the inside and outside. Like Chicle, it is smooth outside and sandwiched inside, with seams and adhesive.

Origins of Neoprene

Most neoprene is produced in Asia. The main suppliers of this material are SHEICO, DAïWABO, YAMAMOTO, and NATIONAL JAPAN.

Physical Properties of Neoprene

• Lightweight: The higher the percentage of closed cells (approaching 100%), the more air the neoprene contains, making it lighter. Closed-cell percentages among brands range from 60% to 93%.
• Insulation: Effective neoprene insulation retains heat longer. A lower absorption coefficient (below 0.5%) indicates better insulation.
• Elasticity: More elastic neoprene reduces muscle fatigue. It is important to consider the lining, which can limit the flexibility of softer neoprene. Choose a wetsuit that fits snugly without compressing, ensuring free movement at the armpits, shoulders, and arms.
• Durability: Pressure can compress neoprene, reducing its thickness and insulation. Durability also refers to resistance to external damage from rocks, shells, and corals. Greater resistance to stretching means a lower risk of tearing.

In Summary:
FLEXIBILITY = FREEDOM OF MOVEMENT

As a bonus, pair your new wetsuit with a mask, snorkel, and fins for a better spearfishing experience!
