One of the most common questions we get asked regarding spearfishing wetsuits is what's the difference between a one-piece wetsuit and the two-piece wetsuit. So we've outlined a few of the differences!
You can read the blog below or watch our video on this topic here:
First up your one piece, as the name suggests, is just one piece everything together. Your two-piece is going to consist of a top with a hood built in and pants. The pants can be high-waist pants. Or they can have the bib and brace built in too, which we call a long john.
So aside from the number of pieces that make up the wetsuit, your one-piece wetsuits will have a zip down the back. It actually reduces the flexibility a lot in the wetsuit. A zip is difficult to get good flexibility out of it because it's metal. Whereas the back of the two-piece wetsuit is really high-flex. That's really important when you're trying to do a duck dive.
If you've got no flexibility, you're going to be very stiff in the water and your technique's not going to be as good. The other disadvantage of having a zip down the back is it generally with these back zip suits, they're using a cheaper zip. This will let a lot of water into the suit so it's not going to be as warm as a two-piece suit. The two-piece suit quite often overlapping the long johns as well, so even more watertight.
Generally one-pieces suit don’t have a hood on it, so you’re going to lose a lot of heat out of your head and also going to let more water in down the back. Two-piece, hoods fully attached. No water should be getting in there if it's been fitted correctly.
Your two-piece suits have a beaver tail system at the bottom. This will stop water flowing up the jacket. It keeps the jacket sealed to the pants. Generally with a buckle system. However we do also have some wetsuits where it's velcro.
One of the other things you'll notice with your one-piece wetsuits because they are targeted at more entry-level spearos, the price points a bit lower. The stitching's actually going to be flatlock. Flatlock stitching penetrates the whole neoprene, so it's going to let some more water in. All of the two-piece wetsuits we carry, are glued blind-stitched so much more watertight.
Overall two piece wetsuits are going to hurt the bank a bit more than a one piece wetsuit, but if your budget allows I think it is well worth it. As you can see with the features we've just gone through, you're going to be much warmer in a two-piece suit and generally they're made out of much stretchier neoprene allowing you to execute a better duck diver and be overall more flexible in the water.
