Donning the Second Skin: Your Essential Guide to Buying and Choosing a Diving Wetsuit

# Donning the Second Skin: Your Essential Guide to Buying and Choosing a Diving Wetsuit

For many divers, a wetsuit is more than just a piece of gear; it’s a second skin, a crucial barrier against the cold embrace of the underwater world. Far from being a mere fashion statement, the right wetsuit is paramount for comfort, safety, and ultimately, the enjoyment of your dive. Without adequate thermal protection, even the most breathtaking reef or fascinating wreck can quickly become an uncomfortable, even dangerous, experience. This comprehensive guide from Scuba Down Under will navigate you through the nuanced world of diving wetsuits, ensuring you emerge with a suit that perfectly complements your diving adventures, whatever the conditions may hold.

## The Essentials: Understanding Wetsuit Types & Function

A wetsuit works by trapping a thin layer of water between your body and the neoprene material. Your body heat then warms this trapped water, creating an insulating layer that significantly slows down heat loss to the colder surrounding water. It's a simple yet incredibly effective principle. However, not all wetsuits are created equal, and understanding the different types is your first step towards making an informed choice.

- **Full Suits (Steamers)**: The most common type, offering full body coverage from neck to ankles and wrists. These provide maximum thermal protection and abrasion resistance. They are available in a wide range of thicknesses to suit various water temperatures. - **Shorties**: As the name suggests, these suits feature short legs and sleeves, ending above the knees and elbows. Ideal for warm water diving (24°C+ / 75°F+) where only minimal thermal protection and sting protection are needed. - **Two-Piece Wetsuits**: Often popular with freedivers and spearfishers, these consist of a long john-style bottom and a hooded jacket that overlaps the waist. The double layer of neoprene over the torso provides excellent warmth without restricting movement, and the integrated hood offers superior head protection. - **Semi-Dry Suits**: These are a hybrid between a wetsuit and a drysuit, designed for colder waters where a wetsuit might struggle but a full drysuit isn't necessary. They feature watertight zippers and seals at the neck, wrists, and ankles to minimise water flushing, keeping the internal water layer more stable and warmer.

## Materials & Thickness: The Core of Thermal Protection

> The primary material for wetsuits is neoprene, a synthetic rubber celebrated for its flexibility and insulating properties. However, advancements in material science have led to various types of neoprene, each offering distinct advantages.

- **Standard Neoprene**: The foundational material, offering good insulation and durability. - **Limestone Neoprene**: A more environmentally friendly alternative, often praised for its superior flexibility and lighter weight compared to petroleum-based neoprene. Brands like Scubapro are incorporating sustainable materials like Yulex, derived from natural rubber. - **Super-Stretch Neoprene**: Engineered for maximum flexibility and comfort, allowing for an unrestricted range of motion. This is particularly beneficial for active divers or those who struggle with traditional wetsuit donning and doffing. Many premium brands now integrate super-stretch panels in key areas.

> Choosing the Right Thickness: This is arguably the most critical decision. Wetsuits are available in various thicknesses, typically ranging from 1mm to 7mm, sometimes even 9mm for very cold conditions. The general rule is: the colder the water, the thicker the wetsuit.

- 1-3mm: Suitable for tropical and warm waters (24°C+ / 75°F+). Offers protection against minor stings and adds a touch of warmth. - 5mm: The most versatile choice for temperate waters (18-24°C / 64-75°F). A good all-rounder for many popular dive destinations. - 7mm: Designed for colder waters (10-18°C / 50-64°F). Often combined with a hood, gloves, and boots for complete thermal coverage. - 9mm+ (or 7mm with an over-vest): For extreme cold, often found in two-piece suits or used in conjunction with semi-dry features.

> Seams: The construction of a wetsuit's seams significantly impacts its warmth and durability.

- **Flatlock Stitching**: Flat seams where panels overlap and are stitched through. Comfortable but allows water to seep through, making it less warm. Common in warm water and thinner suits. - **Glued and Blind-Stitched (GBS)**: Panels are glued edge-to-edge, then stitched halfway through the neoprene, creating a watertight seam. This is the standard for most good diving wetsuits, offering excellent warmth. - **Sealed/Liquid Taped Seams**: An external or internal liquid rubber bead is applied over the GBS seams, creating an even stronger, more watertight seal and enhancing durability. Aqua Lung's "Liquid Fusion Seam Technology" and Mares' "S-Seal" are examples.

## Key Features: What to Look For

> Beyond material and thickness, several design elements contribute to a wetsuit's performance and your overall diving experience.

- **Fit**: The Non-Negotiable Factor: A wetsuit must fit snugly, like a second skin, with no loose areas or excessive bunching, particularly around the torso. Gaps allow cold water to flush through, defeating the purpose of the suit. Conversely, a suit that's too tight can restrict movement, breathing, and circulation, leading to discomfort and potentially dangerous situations. Remember, a good fit is more important than any brand name or feature.

### Zippers: - ** Back Zips:** Most common, easy to use, but can allow some water entry. High-quality back zips often feature internal water barriers or "bat wings" to minimise flushing. - **Front/Chest Zips**: Increasingly popular in surf-inspired designs, offering less water entry and greater flexibility across the back, but can be trickier to don. Aqua Lung's XSCAPE offers a unique surf-style chest zip. - **Ankle/Wrist Zips**: Found on thicker suits, these make donning and doffing significantly easier, especially for 7mm suits.

### Seals: Critical for minimising water entry. - **Neck Seals**: Often smoothskin neoprene to create a good seal against the neck. - **Wrist and Ankle Seals**: Similar smoothskin or O-ring designs. Aqua Lung's "unique connection system" and Scubapro's "Pure Design Concept" focus on effective sealing.

### Reinforcements: - **Knee Pads**: Durable material (like Supratex) on the knees protects the neoprene from abrasion when kneeling on boat decks or rough surfaces. - **Shoulder/Seat Abrasion Protection**: Added durability in high-wear areas. - **Hoods**: Essential for cold water diving, as a significant amount of body heat is lost through the head. Can be integrated into a full suit (like some Aqua Lung Solaflex models) or a separate accessory. - **Pockets & Loops**: Some wetsuits feature small pockets for keys or knives, or loops for attaching accessories.

# Pro-Tip: Maximising Your Wetsuit Investment

> A wetsuit is an investment in your diving enjoyment. Treat it well, and it will serve you for years.

- **Care & Maintenance**: Always rinse your wetsuit thoroughly with fresh water after every dive to remove salt, sand, and chlorine. Hang it on a wide hanger (not a wire hanger, which can crease neoprene) in the shade to dry, inside out first, then right side out. Never leave it in direct sunlight for prolonged periods, as UV rays degrade neoprene. Store it flat or loosely folded to prevent permanent creases. - **Trying On:** The Right Ritual: Trying on a wetsuit can be a chore, but it’s crucial. Use a plastic bag over your hands and feet to help them slide through the cuffs. Take your time, ensure there are no uncomfortable tight spots, and check for excessive loose areas, especially in the small of the back. Perform a range of motions (squats, arm stretches) to ensure freedom of movement. Remember, it should feel snug, but not constrictive. - ** The Vibe:** Ultimately, the best wetsuit is the one that feels right on you. It's a personal choice that balances warmth, flexibility, durability, and budget. Don’t be swayed by marketing alone; trust your comfort and the reputation of the brand.
