Front Zip: With a horizontal zipper on the chest, wetsuits with a Double Front Zip open from the top. This construction allows for an easier entry. Front-zip suits have more stretch in the back panel which gives you a lot more freedom of movement.
Aquabarrier: Aquabarrier is a silicone printing on the collarbone region of your wetsuit. This forms a barrier between the overlapping front zip panels preventing water from entering.
