I don't know why but this makes me think of just stepping out of the car and into a chilly parking lot. Like Hot Cotton, its got the fresh, hot, and metallic molecule called Aldambre in it. Which smells like photorealistic metal mixed with steam. But Ultrae also has a slightly chilly, icy aspect to it which I think may have been teased out by the floral notes which add a bit of a soft greenness to the composition. It's icy and crisp but also I think of a warm car because there's a hint of leather and hot air. It kind of captures that liminal space between outside and inside. Would be the signature scent of a very cool person who wears cyberpunk metal jewellery or something.
