DUI DuoTherm II 300 Mid Layer Long Sleeve Top Large

Stay Warm and Focused with Reliable Thermal Control
Cold water diving demands gear that performs without compromise. The DuoTherm II 300 Long Sleeve Top delivers consistent warmth, reliable performance, and lasting comfort in water temperatures from 45 to 60 Degree F. Designed as part of a versatile two-piece system, it gives divers the ability to fine-tune their thermal protection while maintaining full mobility and layering flexibility.

Performance Fleece That Moves With You
This long sleeve thermal top for diving is made from heavy stretch fleece (560 gm/sq. m), offering both insulation and freedom of movement. The all-way stretch construction adapts to your body, while accent stitching reinforces durability. Thoughtful features like thumb loops help prevent sleeve shifting while gearing up, and hand warmer pockets add post-dive comfort between sessions. It's a practical choice for divers who want a balance of warmth and function.

Smart Wicking Technology for Lasting Dry Comfort
With Active Wicking Technology (AWT), this top is engineered to handle moisture where it matters most. The inner fleece lining pulls sweat and condensation away from your body, helping to keep you dry throughout your dive. The outer surface resists incidental water contact from splashes or gear handling, adding an extra layer of assurance when you need it most. Whether you're exploring, training, or working in colder environments, this mid layer top is built to perform.
