Since it’s introduction the Waterproof D7 has been the prime choice of drysuit within the advanced diving community. Even though the Waterproof D7 was a modern and extremely well-performing drysuit, the R&D at Waterproof decided to give it a major overhaul. Recent development in material and enhanced polymer science has made it possible to perfect the Waterproof D7 concept. Changes were made to make diving in challenging environments a more pleasurable and effortless experience. Nylotech, a new material developed to be softer, yet more resistant to abrasion. Nylotech has been abrasion tested (200.000 rubs) by the Martindale Method according to SS-EN ISO 12947-2:2017. A reshaped and slimmer fit resulting in a less bulky drysuit. New longer and curved zipper, placed higher up on the shoulder to enhance upper body movement as well as providing effortless donning and doffing in an effort to boost the overall diving experience. The zipper is protected by an improved Outer Coil Zipper No.10 with fabric backing, ensuring the functionality of the drysuit and safety of the diver. Wrist seals are equipped with the SI TECH QCS ring system optimised for the use of the ULTIMA dry glove system. Improved boots utilising a newly researched and hardcore tested rubber formula. In addition, the rest of the external add-ons like pockets and abrasion areas have received a well-deserved face-lift, making the Waterproof D7X the most modern drysuit on the market.
