Billabong Women's Furnace Synergy 4/3mm Back Zip Full Wetsuit - Black

Questions From Buyers

What do the numbers mean in the title (like 5/4, 4/3, 3/2)?
The numbers refer to the thickness of the wetsuit in millimeters. For two numbers (like 3/2) the first number refers to the thickness of the material around your core (3mm) and the second number refers to the thickness of the material around the arm and leg (2mm). The extremities typically have thinner material to increase movement while the core is thicker to increase warmth.

What thickness is best for you depends on a number of factors like body type, activity level, and outdoor temperature. As a general rule, a 3/2 suit is good for water in the 60s. 4/3 is best for water in the 50s. And 5/4 may be best for water in the 40s. No one likes being cold so if you get cold fast, choose a thicker suit.

Is a back zipper better than chest zipper?
It's all personal preference. As a general rule, chest zip wetsuits are harder to put on/take off but may decrease the amount of water that leaks down your back. Chest zip designs are harder to manufacturer and as a result are typically a bit more expensive.
