You’ll find that when shopping for wetsuits, there are different options for zippers, which ultimately determine how you’ll get in and out of the suit itself.
Back Zip: A back zipper is common on wetsuits, allowing the suit to open vertically down the back. This makes it easy to get in and out of your suit but can also somewhat limit flexibility.
Front Zip: A front zipper zips down the front of a wetsuit for an extremely easy way to get your suit on and off.
Chest Zip: A chest zipper is found horizontally on the chest of the wetsuit and allows for increased flexibility in the back of the suit. The chest zip is the most popular method of entry for surfers.
Zipper Free: A zipperless wetsuit is made without zippers and are usually found in higher end, performance type wetsuits. They’re made out of extremely stretchy neoprene for a reasonably easy zipper free entry. Zipper free wetsuits tend to be the most flexible.
