The Drass D-One Commercial Diving Helmet
“Attractive” might be the wrong word, but I do find beauty in a highly complicated form-follows-function object like this. This is the D-One Commercial Diving Helmet produced by Italian manufacturer Drass Galeazzi:
The design features a 30-degree angle in the back of the helmet, providing an improved range of motion and allowing the wearer to comfortably tilt their head back to look upwards.
The helmet can be kitted out with a camera, a light, a welding shield, a defogger and a water shroud (to protect the valves in debris-laden water).
To don or doff it, your head goes through this neoprene “neck dam” in the bottom.
This video gives you a look at how all of the features work:
