It's not the amount, it's the ingredients.Sorry for being a Doubting Thomas, but I didnt believe you until I tried it today. Two sprays. Smart strength. I'm literally dumbfounded how this is possible.
Also the individual sprayers differ.
I wear a Guerlain frequently, it's an EdT. Not only is one spray huge, it projects right at my upper limit for 30 minutes then settles down for about 4-6hrs. Traditional Colonia, which is EdC, confusingly, not only doesn't project no matter how much you spray. It is also dead within an hour.
I was going to recommend Shawn's Chatillon Lux samples earlier for the sensitive nose. They are only moderate projection or less and are gone within 3-4hrs. Plus they match the DG aftershaves as mentioned.
