Billabong also makes intermediate sizes (MS, MT, LS, LT…) that we don't always have in store. If you're between two sizes, go by chest and height: the wetsuit should fit snugly, with no air pockets in the back or armpits. Check the selector for the sizes available in store and, if in doubt, have a look at our guide to choosing the perfect wetsuit.

Frequently asked questions
What water temperature is a 5/4 for?
A 5/4 is designed for cold water, the kind you get in the depths of winter on the Atlantic or in northern Spain. In the Mediterranean it's usually enough on the coldest days of the year.
Back zip or chest zip?
A back zip makes it easier to put the wetsuit on and take it off; a chest zip seals a little better. The Intruder Back Zip prioritises comfort and durability.
What should I pair it with in the depths of winter?
On the coldest days, a pair of Billabong neoprene gloves helps you stay in the water longer.
