Continuation of my question: "Why does the description specifically state - Not for Snorkeling and SCUBA diving". Additional flexibility in shoulders and arms, though not highly beneficial in SCUBA, does not exclude a wetsuit for diving. Since it is excluding the suit for diving, there must be some property that makes it "unsuitable" (excuse the pun) for SCUBA usage.
The Rip Curl Elastomax Super-Stretch wetsuit will stretch over 200% more than standard neoprene. This hydrophobic 'E3' neoprene repels water to keep you warmer longer. The body is of 3mm thickness for greater warmth, while strategic panels are of 2mm thickness for ultimate mobility and comfort. The chest, back and torso are lined with Rip Curl's Fireskin fiber that repels water and keeps the body warm. The interior panel 'Batwing' is designed to prevent waterflow and maximize warmth. The Rip Curl Elastomax Super-Stretch wetsuit has flexible kneepads for brilliant grip and durability. It also has a hidden key pocket for convenience. This suit is not designed for snorkeling or scuba diving.
