Things to Look for in 4/3 Wetsuits 

Here is what you should be looking for in 4/3 wetsuits.

Size and Fit 

A wetsuit works by trapping and warming a fragile layer of water against your skin. So, it must fit correctly. Suits that fit loosely will take on too much water.

You must choose a 4/3 wetsuit size that fits snugly, and there’s no bunching in the legs or arms.

But the wetsuit should not be too tight to the extent that it restricts your breathing and movements.

We recommend using your height and weight to determine the ideal size on the manufacturer’s sizing chart, which is usually provided on the product page.


The performance and durability of a 4/3 wetsuit depend mostly on the construction. In this case, we are talking about the seams and seals in the suit.

The most popular types of constructions are flatlock stitching, blind stitching and gluing, blindstitching, gluing, and taping. The most durable design is the third one, blindstitching, gluing, and taping.


Never choose a wetsuit that feels like a rubber straight jacket. Instead, go for a 4/3 wetsuit that is much more elastic. Preferably, one that is made with one hundred percent super-stretch neoprene.

Final Thoughts 

For this roundup, the winner is Rip Curl Dawn Patrol Chest Zip 4/3 Wetsuit.

This is an incredible all-around wetsuit that provides the features of a high-end wetsuit at an economical price point. It is a superior choice for both beginners and experts.
