Frequently asked questions

What does 4/3 mean?

It means 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 in mainland Spain.

Back zip or chest zip?

A back zip is easier to put on; a chest zip lets in less water. If you prefer the latter, there's the women's Billabong Foil 4/3 mm chest zip.

What else do I need for winter?

For the coldest days, pair it with the women's Billabong Synergy 2 mm gloves.
