Kenzo pour Homme
To the O.P: I apologise in advance for breaking your no niche rule, but I feel really strongly about recommending Ineke Derring Do. It is an amazing floral aquatic, which is very complex in its development. No perfume before or since has captured rain in the same way.
Again sorry, because you've explicitly stated "No Niche", but this should be easy to test and near the same price as designers.
@SoS: I love Bleu de Channel but I agree with you that it is not aquatic, so I wont recommend it as one.
