We developed this suit to give divers the widest possible spectrum of temperature applications. If you are someone who dives down south as well as locally this might very well be the best solution for you.

5mm long john with 5mm hooded jacket means that the diver has 10mm insulating their core.

We used top of the line Sheico L foam which is extremely warm without compromising dexterity. Sheico L foam is  the highest grade neoprene in the world. Sheico L Foam insulates just as well the acclaimed Yamamoto 45 (and 30% better than generic Chinese neoprene). It is comparable in density and compression resistance to Yamamoto 45 (and nearly 70% greater than Yamamoto 39). It is extremely warm, stretchy but also resilient over many uses meaning this suit will retain its thermal properties for many hundreds of dives.

Reinforced seals do a tremendous job of mitigating water flow in and out of the suit. A built in hood dramatically improves body heat retention by minimizing water seepage around the neck.

Single lined “open cell” construction maximizes the dynamic range of the super stretchy neoprene in order to make this suit exceptionally comfortable and decrease inherent fatigue from wearing a tight wetsuit.

This suit can also be worn as just the hooded jacket, or just the long john if the diver is using it in more temperate climates or water temperatures. In fact many of our divers wear just the long john with a rash guard on top, or just the hooded jacket with board shorts at the bottom when we dive down south.

This suits are manufactured in Italy, ethically and exclusively for the Dive World brand to the highest build quality. We are very proud of this product and can wholeheartedly recommend this to any diver as a genuine product worthy of our reputation.
