Trilaminate Vs Neoprene Drysuits: The Scuba Divers Guide

Hey there, diving enthusiasts! When it’s time to select a drysuit, the material is a crucial choice that can shape your diving experience. Whether you lean towards the versatility of trilaminate, the warmth of neoprene, or the unique properties of crushed neoprene, understanding their pros and cons is key. Let’s dive into the specifics to help you make the best pick for your scuba adventures.

Trilaminate Drysuits

Trilaminate drysuits, also known as membrane drysuits, are known for their three-layered design. Each layer plays a crucial role: an outer layer that wards off abrasion, a middle waterproof and breathable membrane, and an inner layer for added durability. This trio works together to offer divers a unique combination of protection and flexibility.

Construction: The seams of a trilaminate suit are usually first glued and then sewn for extra strength. Sewn seams are often taped internally to ensure watertight integrity.

Trilaminate Materials:

  • Nylon: offers a good balance between durability and flexibility, suitable for a variety of dives.
  • Polyester: similar to nylon but can provide slightly different wear and tear characteristics, also widely used in trilaminate drysuits.
  • Cordura: Known for its resistance to abrasions and tears, Cordura is often used in high-wear areas or in suits designed for rugged diving environments.

Additionally, many brands develop their own blends or special materials to enhance performance, durability, or comfort.

Advantages:

  • Flexibility and Mobility: Trilaminate drysuits are celebrated for their flexibility. They don’t restrict movement, making them perfect for manoeuvres in tight spaces or intricate underwater photography.
  • Lightweight: These suits are a blessing for travelling divers. Their lightweight nature means they’re easy to pack and won’t weigh you down on your journey.
  • Customisation Options: One size does not fit all in the world of diving. Trilaminate drysuits offer extensive customisation options, from tailored fits to varying boot and seal types, adapting to every diver’s unique needs.

  • Quick Drying: Their quick-drying feature benefits divers on multi-dive trips, allowing for a comfortable and dry experience dive after dive.

Disadvantages:

  • No Thermal Insulation: Unlike neoprene, trilaminate suits provide minimal thermal insulation on their own. Wearing an appropriate undersuit is essential to stay warm, especially in cold water.
  • Less Stretch in Fabric: The material used in trilaminate suits has limited stretch. These suits tend to have a baggier fit to accommodate movement and flexibility, which might feel less streamlined underwater.

Best Use Scenarios:

Trilaminate drysuits are ideal for technical diving, underwater photography, and situations where flexibility and customisation are key. They are also a great choice for divers who need a suit that can adapt to various temperatures by changing the undersuit. 

Neoprene Drysuits

Neoprene drysuits, similar in material to wetsuits, provide excellent thermal insulation and are a popular choice among cold-water divers. These suits are made from either standard or crushed neoprene.

Construction: Neoprene suits are generally glued and then blind stitched, a process that doesn’t fully penetrate the neoprene, preventing water ingress through the seams. High-stress areas might also be taped for additional security.

Materials:

  • Crushed Neoprene: These drysuits are made by compressing standard neoprene, reducing its buoyancy while retaining thermal protection but still not as warm as standard neoprene.

Advantages:

  • Thermal Insulation: The natural insulating properties of Neoprene reduce the need for heavy undergarments, making these suits ideal for very cold water.
  • Durability: Neoprene is known for its toughness, especially in harsh underwater environments. Crushed Neoprene, being denser, can offer even greater resistance to abrasion and punctures.
  • Ease of Repair: Like its regular counterpart, crushed Neoprene can also be repaired relatively easily, allowing for extended suit life and utility.

  • Snug Fit: Neoprene’s stretchiness allows for a closer, more body-hugging fit, enhancing comfort and streamlining underwater movement.

Disadvantages:

  • Weight and Bulkiness: Neoprene suits tend to be heavier and bulkier, making them less convenient to transport, particularly for travelling divers.
  • Buoyancy and Compression: Neoprene’s inherent buoyancy can be a challenge, especially at depths where compression reduces this buoyancy. With neoprene drysuits, divers often need more weight on the surface as they do at deeper depths.

Best For:

Neoprene drysuits are a top pick for divers venturing into the chillier waters of the world. They provide essential warmth in cold conditions and are ideal for divers exploring rough underwater terrains, like wreck diving or cave diving, where durability is key.

How To Make Your Choice

Deciding on the right drysuit is more than just a choice between Trilaminate and Neoprene; it’s about tailoring your gear to your unique diving lifestyle. Here are some key factors to consider:

  1. Water Temperature: Are you diving in icy waters or moderately cold environments? Trilaminate suits are versatile with layering options, while Neoprene offers inherent warmth.
  1. Diving Activity: What will you be doing underwater? For intricate activities like underwater photography or cave diving, the flexibility of a Trilaminate might be beneficial. For rugged, cold-water dives, Neoprene’s durability and insulation are advantages.
  1. Layering Preferences: Do you prefer to adjust your warmth with different undergarments, or do you like the simplicity of built-in insulation? Trilaminate requires additional layers for warmth, whereas Neoprene provides more built-in thermal protection.

  1. Fit and Mobility: Consider how you like your suit to fit. Do you prefer a snugger, body-conforming suit (Neoprene), or a suit that’s more flexible in fit (Trilaminate)? To find the perfect fit, check out our guide on How to Find Your Perfect Drysuit Fit.
  1. Travel Considerations: If you’re a diver on the go, the weight and bulkiness of your suit can be a deciding factor. Trilaminate suits are generally lighter and easier to pack.

  1. Personal Preference in Buoyancy and Fit: Each material behaves differently underwater, especially regarding buoyancy and compression. Trilaminate suits offer more consistent buoyancy across depths, whereas Neoprene suits require more weight adjustment.

Recommendations:

The best way to know what works for you is to try on different suits. Fit, comfort, and personal preference are as important as the technical specifications. Visit your local dive shop to try on both Trilaminate and Neoprene drysuits. Pay attention to how they feel, move with you, and consider how they align with the type of diving you plan to do.
