Scuba diving is an adventure that transcends the ordinary, inviting enthusiasts into an aquatic realm where the chill of the water can be just as memorable as the beauty beneath the waves. For divers committed to comfort and performance, the choice of thermal protection is paramount. Diving Unlimited International (DUI) has long been a leader in creating gear that not only withstands the pressures of the deep but also keeps divers warm and comfortable. Among their offerings, the DUI DuoTherm 2 jumpsuit stands out for its versatility, available in different thicknesses to cater to a wide range of diving conditions. Here, we delve into the specifics of this undergarment, exploring its different thicknesses and what each offers to the modern diver.

Understanding the DUI DuoTherm 2 Jumpsuit Before diving into the specifics of thicknesses, it’s crucial to understand what makes the DuoTherm 2 jumpsuit a favorite among divers:

• Material: The jumpsuit is constructed from all-way stretch fleece, providing flexibility and comfort. This material is not only soft against the skin but also retains heat well, crucial for thermal protection.
• Technology: The DuoTherm 2 uses Active Wicking Technology (AWT). This means it repels water from the outside while wicking moisture away from the body on the inside, helping to keep the diver dry and warm.
• Design: The jumpsuit design is sleek, offering a one-piece solution that simplifies gearing up and reduces the risk of water ingress through layering gaps.

Comparing the Thicknesses When choosing the right thickness of the DuoTherm 2 jumpsuit, consider:

• Water Temperature: The primary factor. Always align the thickness with the coldest expected water temperature.
• Dive Activity: If you're planning on long dives or dives with significant depth changes, consider the insulation needs at depth where temperatures drop.
• Personal Comfort: Some divers feel colder or warmer than others. Personal comfort plays a significant role.
• Layering Potential: Thinner suits allow for more layering options, whereas thicker ones might limit the need for additional garments.

Maintenance and Care Regardless of thickness, maintaining your DuoTherm 2 jumpsuit involves:

• Washing: Use mild detergent to preserve the fleece's properties. Avoid fabric softeners as they can reduce the wicking efficiency.
• Drying: Air drying is best; tumble drying on low heat can be used sparingly.
• Storage: Store away from direct sunlight in a cool, dry place to prevent material degradation.

Conclusion The DUI DuoTherm 2 undergarment jumpsuit offers divers a tailored approach to thermal protection. Whether you're plunging into the icy depths or exploring the warm shallows, there's a thickness suited to your needs. The choice between 150, 250, or 400 depends on your diving environment, personal comfort, and the type of dives you undertake. Each thickness brings its unique benefits to the table, ensuring that no matter where or how you dive, your focus remains on the underwater world, not on battling the cold. By understanding these options, divers can equip themselves with confidence, knowing they have the right gear for whatever adventure lies beneath the surface.
