Product highlights
THERMAL COMFORT
TechnoButter 3 Firewall is one of the most insulative, lightest neoprene foam core ever, with heat retaining therlam interior layer and quick dry properties
DURABILITY
Designed for long-lasting use - reinforcements in critical areas, innovative panel joints and fluid seam weld increase the durability and resilience of the foam
ELASTICITY
Pre-stretched neoprene with featherlight, envy foam rubber core. The lightest, most flexible, softest material ever crafted. Superior flexibility and fit
MODULAR CLOSURE
Switch between a hooded and a non-hooded configuration, making it adaptable to different water conditions! The hood and collar are interchangeable, so you can easily detach the hood and replace it with a standard collar when you don’t need the extra protection
Features

- Wetsuit thickness 5/4 mm - This model has 2 foam thicknesses of 5 and 4 mm. The torso is the most exposed to cooling, so the wetsuit is thicker here
- Waterproof Zip on the front - Front Zip is positioned at the width of the chest, so it is short and sits high, therefore allowing less water to pass through and keeping you comfortable for longer during your session. F.U.Z.E. stands for Front Upper Zip Entry, which is the front fastening at the upper part of the body
- Krypto Knee Pads - The knee area uses a fabric with increased resistance to minimise possible abrasion in the most vulnerable areas
- 360° Barrier with Drain Holes - Strategically placed drain holes ensure that water drains quickly from the inside of the wetsuit
- Aqua Solvent Free - The materials used were created entirely water-based, with no organic solvents or VOCs. The use of solvents has been reduced by 600 grams per foam
- External Key Pocket with Loop - Enjoy your session and stop worrying about your keys thanks to the dedicated loop pocket
- Fluid Seam Weld - Triple Glued and Blindstitched with Exterior Fluid Seam Weld Technology
- Contortionist Seamless Shoulder - This innovative design eliminates seams in the shoulder area, allowing for a greater range of motion and reducing the risk of chafing or irritation
