Women's Wetsuit: Complete Guide to Choosing the Right One

Scuba diving is an invitation to silence, to submerged beauty, to that rare feeling of floating between two worlds. To fully enjoy it, your women's wetsuit must become one with you: neither too tight nor too loose, protective without trapping you. At Couleurs Lagon, we design wetsuits for women passionate about the ocean — combining premium Yamamoto neoprene, UPF50+ protection, and designs inspired by the lagoons of New Caledonia. This guide helps you choose the right wetsuit based on your activity, water temperature, and body type.

1. What thickness for what water temperature?

Neoprene thickness is the first criterion to consider. It directly determines your thermal comfort underwater.

Tropical waters (+ 24°C) — 2 to 3 mm

In New Caledonia, Polynesia, or the Caribbean, surface temperatures often exceed 26°C. A thin 2 to 3 mm wetsuit is sufficient: it protects against UV rays, jellyfish, and coral scrapes while offering complete freedom of movement. This is the ideal configuration for snorkeling, freediving, and recreational diving in warm waters.

Temperate waters (10°C to 20°C) — 5 to 7 mm

For colder destinations — the Mediterranean in winter, the Atlantic, the North Pacific — a 5 to 7 mm wetsuit is essential. The thickness ensures effective thermal insulation even during prolonged dives. The compression resistance of Yamamoto neoprene guarantees that this insulation remains stable at depth, where other neoprenes tend to compress.

2. One-piece or two-piece?

Second big choice: one-piece (full suit) or two-piece (shorty + hood, or jacket + pants)?

• Long-sleeve one-piece: the most versatile solution. Full body protection, optimal sealing at junctions. Ideal for most female divers.
• Shorty (short sleeves, short legs): lighter and easier to put on, perfect for very warm waters and short sessions.
• Backless wetsuit: maximum freedom of movement, assertive look. Recommended for freediving and snorkeling in tropical waters.
• Two-piece: allows for double insulation by layering two thicknesses. A modular solution for variable conditions.

At Couleurs Lagon, our range covers long-sleeve and backless wetsuits in 2mm Yamamoto neoprene — designed specifically for warm and temperate water activities.

3. Yamamoto neoprene: why it's different

Not all neoprenes are created equal. At Couleurs Lagon, we exclusively use Yamamoto type 39 neoprene, a benchmark in the high-end surf and dive industry.

Unlike traditional petroleum-derived neoprene, Yamamoto is made from limestone — a more abundant and less polluting natural resource. Its closed and uniform cellular structure gives it four key advantages:

• Superior thermal insulation: the cellular structure retains body heat more effectively, even under compression at depth.
• Increased elasticity: up to 30% more stretchy than standard neoprene, for total freedom of movement.
• Durability: significantly superior wear and compression resistance — your wetsuit lasts longer.
• Environmental respect: made from natural materials, it aligns with our commitment to more responsible aquatic fashion.

4. Maintenance: preserving your wetsuit over time

Regular maintenance is the best way to protect your investment. Here are the essential steps after each session:

• Rinse with fresh water: mandatory after each outing to remove salt, sand, and sunscreens that degrade the neoprene.
• Dry in the shade: UV rays and direct heat weaken the fibers. Hang your wetsuit in the shade on a wide hanger.
• Store flat or on a hanger: avoid repeated folding in the same place, which creates cracks.
• Specific neoprene products: for deep cleaning (odors, mold), use a shampoo designed for neoprene — never a classic detergent.

5. Why choose Couleurs Lagon?

Couleurs Lagon is a brand born in New Caledonia, in one of the most beautiful lagoons in the world. Our women's wetsuits are designed for women who truly dive — not catalogue visuals, but equipment designed for practice, with a true visual identity.

• Yamamoto type 39 neoprene: the best material on the market, period.
• UPF50+ protection: because in tropical diving, the sun is a real risk.
• Ocean-inspired designs: vibrant lagoon colors, marine patterns, feminine silhouettes. Feeling beautiful underwater is also important.
• Women-specific cuts: no adapting men's models — cuts designed for female body shapes.

6. Size guide: finding the perfect fit

A well-fitting wetsuit is essential: too big, water circulates freely inside and cancels the thermal effect. Too tight, it hinders breathing and movement.

• Measure chest, waist, and hips with a soft tape measure, ideally on an empty stomach in the morning.
• Consult the size guide on each product page — our wetsuits are available in XS to XL with precise measurements.
• If in doubt between two sizes: choose the smaller one. Yamamoto neoprene will soften slightly with use.
• Try it on dry: the wetsuit should be snug everywhere without being painful. A few arm rotations and bent knees confirm the good fit.
