Professional Wetsuit Usage Guide: A Comprehensive Manual from Selection and Donning to Maintenance
Wetsuits are essential gear for scuba diving, freediving, and various water sports. They serve not only as thermal insulation but also as a protective barrier against scrapes, punctures, and jellyfish stings underwater. Proper use and maintenance of wetsuits significantly enhance diving comfort, extend equipment lifespan, and ensure safety. This article provides a comprehensive professional guide covering the entire wetsuit usage process.
I. Core Functions and Importance of Wetsuits
1. Thermal Insulation: Water conducts heat 25 times faster than air. Wetsuits create a “thermal layer” by trapping a thin layer of water against the skin surface, which is warmed by body heat. This slows heat loss and prevents hypothermia.
2. Physical Protection: Effectively shields divers from abrasions caused by sharp objects like coral, rocks, and metal structures, while also guarding against stings from marine life such as jellyfish.
3. Buoyancy Support: The material of the wetsuit (especially neoprene) inherently provides positive buoyancy, helping conserve energy.
4. Sun Protection: Offers physical sunblock for the skin, blocking UV rays both above and below the water surface.

II. Classification and Selection of Wetsuits
1. Material Classification:
Foamed Neoprene: The most common material, containing countless nitrogen bubbles that provide excellent insulation and buoyancy. Classified by manufacturing process:
Standard Nylon Fabric: Both inner and outer layers are nylon-wrapped, offering good durability and high cost-effectiveness.
Super Stretch/Smooth Liner: Extremely smooth inner lining for easier donning/doffing, snug comfort, and superior insulation, though pricier.
Titanium/Metal Liner: Reflects body heat for enhanced thermal retention at equivalent thickness.
Sharkskin: A biomimetic material that insulates by trapping air layers. Lightweight and quick-drying, it's ideal for warm waters and active diving.
Semi-dry/Dry Suits: Utilize closed-cell foam rubber or reinforced fabrics with waterproof zippers and sealed neck/wrist seals to minimize water ingress. Designed for cold water or ice diving.
2. Thickness Matching Water Temperature:
0.5mm - 2mm: Suitable for tropical waters above 26°C. Primarily for sun protection and light coverage.
3mm: Suitable for temperate waters between 21°C and 26°C. The most common all-purpose thickness.
5mm: Suitable for cold water between 16°C and 21°C. Typically a full-body suit or a hooded full-body suit.
7mm and above / Semi-dry / Dry suits: Suitable for cold water below 16°C or ice diving.
3. Style Selection:
Full-body: Covers the entire body, offering the best insulation.
Short-sleeve/short-pants: High flexibility, ideal for the warmest waters.
Two-piece: A jacket and pants that can be worn together, adapting to varying water temperatures with excellent insulation.
Key Selection Principle: Fit is paramount! The suit should hug like a second skin without constricting breathing or circulation. During in-store fitting, perform movements like squats and arm raises to check for excessive strain or gaps.
III. Professional Donning and Doffing Guide
Proper donning and doffing techniques not only protect your wetsuit but also make the process easier.
Donning Steps:
1. Preparation:
Ensure both your body and the interior of the wetsuit are dry. Apply a small amount of talcum powder to your body or use a specialized wetsuit lubricant to reduce friction.
Stretch the openings at the ankles, wrists, and neck as wide as possible.
2. Step-by-Step Donning:
Legs First: Pull the legs up gradually, like putting on socks, avoiding digging with fingernails.
Arms Next: Use the same method for the arms.
Zip Up: Have a buddy assist with the back zipper. If alone, use a pull rope. Never force it!
Adjustment: Ensure snug fits at the neck, wrists, and ankles with no large wrinkles or gaps. Otherwise, the “scouring effect” may occur, allowing cold water to continuously flow in and rapidly steal body heat.
Removal Steps:
1. Remove the top half first: Unzip the back, remove one arm, then the other.
2. Roll-off method: Roll the top section down to your waist, then grasp the waistband and pull the entire suit off like removing a sock. This is the most effective and least damaging method.
IV. Precautions During Diving
Before Entering Water: Wet the neck and wrist areas to expel trapped air, ensuring a snug fit.
On Board/Shore: Avoid sitting directly on rough or dirty surfaces to prevent abrasion and contamination. In hot weather, cover the suit with a damp towel or submerge it in water to shield rubber from sun exposure and aging.
Underwater: Be mindful of your surroundings to avoid vigorous friction against sharp coral or rocks.
V. Post-Dive Cleaning and Maintenance
This is the most critical step for extending your wetsuit's lifespan.
1. Immediate Rinse: After each use, thoroughly rinse both inside and outside with running fresh water, paying special attention to zippers, Velcro, and seals to remove salt, sand, and chlorine.
2. Gentle Cleaning: Use specialized wetsuit detergent. Never use laundry detergent, soap, or any strong acidic/alkaline cleaners.
3. Proper Drying: Hang on a wide, curved hanger or fold it in half and hang on a hanger with multiple support points. Avoid thin wire hangers, which can leave permanent creases on the shoulders and damage the thermal bubble structure.
4. Air Dry in Shade: Never expose to direct sunlight or use heaters/hairdryers for drying. Heat is neoprene's worst enemy, causing it to harden, become brittle, and lose elasticity.
5. Long-Term Storage: Ensure complete dryness before storing flat or loosely rolled in a cool, dry, well-ventilated area. Avoid excessive compression.
VI. Special Care for Zippers and Hook-and-Loop Fasteners
Zippers: Rinse thoroughly after each use. Apply paraffin wax or specialized zipper lubricant periodically (never use industrial lubricants like WD-40) to maintain smooth operation. If resistance occurs while zipping, do not force it. Instead, unzip slightly and try again.
Velcro: After use, remove any hair or fibers from the hook side and press it firmly against its corresponding loop side. This prevents the hook side from catching on other parts of your wetsuit, causing snags.
Conclusion
Your wetsuit is your faithful companion for underwater adventures. Invest in a high-quality wetsuit and provide it with professional care, and it will reward you with countless warm, comfortable, and safe underwater journeys. Remember, proper use and meticulous maintenance are just as valuable as the wetsuit itself. Happy diving!
