Billabong 4/3mm Foil - Chest Zip

The Billabong Foil 4/3 mm chest-zip is a men's full suit for surfing in cold and mild water. It combines a durable Superflex exterior with partly recycled Superlight foam, and the chest entry reduces the water that seeps in through the back.

Who it's for

• Surfers looking for a simple, warm 4/3 for the cold season.
• Anyone who prefers a chest zip for a better seal.

Features

• Superflex: durable, very stretchy outer fabric of neoprene and nylon.
• Superlight Foam: lightweight foam made by combining recycled car tyres and neoprene offcuts, with good stretch and heat retention.
• Stretch silicone inner fabric.
• GBS outer seams (glued and blind-stitched) for maximum flexibility and minimal water entry.
• Inner seams reinforced with Melco tape in the highest-stress areas.
• Partly recycled materials.
• Long-sleeve full suit, 4/3 mm, with a high collar and chest-zip entry.
• Composition: 80% neoprene, 20% nylon.

Frequently asked questions

What does 4/3 mean?

That the neoprene is 4 mm on the torso, for warmth, and 3 mm on the arms and legs, for freedom of movement. It's the usual thickness for autumn, winter and spring on the Iberian Peninsula.

What's the advantage of a chest zip?

Because it's at the front, less water gets in than with a back zip, and the back stays more flexible.

What else do I need for winter?

On the coldest days, a pair of Billabong Absolute 3 mm gloves helps keep your hands warm.
