How to Choose the Best Diving Suits

Understanding Wetsuit Thickness

Wetsuit thickness is measured in millimeters (mm) and is the primary factor in determining thermal protection. Thicker suits offer more warmth but can restrict movement.
  • 1-3mm: Ideal for warm water diving (70°F/21°C and above). Offers basic thermal protection and abrasion resistance.
  • 3-5mm: Suitable for temperate waters (60-70°F/15-21°C). A versatile choice for many divers.
  • 5-7mm: Recommended for colder waters (50-60°F/10-15°C). Provides significant warmth but may require more effort to move in.
  • 7mm+: For very cold conditions or extended dives in temperate waters. Often used with hoods and gloves.

Wetsuit vs. Drysuit

The fundamental difference lies in how they insulate. Wetsuits use a thin layer of water trapped between the suit and your skin, which your body heats up. Drysuits keep you completely dry by using undergarments for insulation, making them suitable for colder conditions.
  • Wetsuits: More affordable, easier to put on, and allow for greater flexibility. Best for warmer to moderately cool water.
  • Drysuits: Offer superior thermal protection in very cold water, keep you dry, and can be layered for different temperatures. They are generally more expensive and complex to use.

Fit and Features

A proper fit is paramount for both warmth and comfort. The suit should be snug but not constricting, with no major gaps, especially around the neck, wrists, and ankles. Key features to consider include:
  • Seam Construction: Flatlock seams are common in warmer water suits, while sealed or taped seams provide better waterproofing and durability for colder conditions.
  • Entry System: Back zips are standard, while front zips offer more flexibility. Zipperless suits can provide a more streamlined fit.
  • Neoprene Quality: Higher-quality neoprene is more flexible and durable, offering better performance and longevity.

Frequently Asked Questions

How should a diving suit fit?
A diving suit should fit snugly like a second skin, without being uncomfortably tight. There should be no excessive bagginess, especially around the torso, arms, and legs, as this allows cold water to flush in and out, reducing insulation.
What is the difference between a wetsuit and a rash guard?
A wetsuit provides thermal insulation by trapping a layer of water against the skin, which is then heated by the body. A rash guard is a thin, flexible garment made of lycra or nylon, primarily designed to protect against sun exposure, minor abrasions, and chafing.
How do I care for my diving suit?
After each use, rinse your suit thoroughly with fresh, cool water, both inside and out. Hang it to dry completely on a padded hanger, away from direct sunlight or heat, to prevent material degradation.
Can I wear a wetsuit in very cold water?
For very cold water, a thicker wetsuit (7mm or more) is recommended, often combined with accessories like gloves, boots, and a hood. For extreme cold, a drysuit is generally a better option as it keeps you completely dry and allows for adjustable insulation.
What is neoprene?
Neoprene is a type of synthetic rubber that is flexible, durable, and provides excellent insulation. It's the primary material used in wetsuits, with its thickness and quality significantly impacting the suit's warmth and performance.
