Way back, 6 years ago, when the line was first introduced (back when online decanting websites were sort of a rarity), I bought a 12-pack of 1 ml of each of the PB's and smelled them the week they were released by the Tom Ford boutique on Madison Avenue (when they were released, this was the ONLY place you could buy the scents, there weren't sold in stores).
It was tough spending 12 days wearing 1 sample a day, but I did it and of course there were some that I initially loved and others that took more time to grow to love - and of course, others that I hated and I still hate.
Moss Breches was one that I felt very indifferent about. Yeah, it's 'green', it was 'mossy' to my (at the time) inexperienced nose but it sort of bored me. I remember being (like many guys here on BN) immediately drawn to Tobacco Vanille and Tuscan Leather, but not really MB. Fast forward a year or so, I sort of fell under the spell of Chypres when I bought vintage Mitsouko and the fantastic modern, masculine chypre, Numero Uno by Carthusia. All of a sudden, the bergamot/patchouli/moss combination that is features in a chypre really clicked in my head. I finally 'got' it. It was immediate and very pleasing and it was then that I retried Moss Breches and immediately I realized that TF had released a very unisex Chypre, well a sub-Chypre, since technically I don't think it actually has oakmoss in it, it just smells like it does.
When they discontinued this, I really felt sad, since I think it's just a beautiful modern, new interpretation of the Chypre category. Which fell in line with the aesthetic that I think Tom Ford has championed for years: the retro glamour that he has sought for in many fragrances (when he was at YSL he released Rive Gauche Pour Homme which harkens back to Barbershop fougeres, he released both Grey Vetiver and Noir - both of which nod affectionately to Guerlain masculines, Vetiver and Habit Rouge, his feminine for Estee Lauder, when he worked for them, Azuree Soleil Eau Fraiche which re-enlivened the feminine classic in a new, beachy way, etc...).
If you can find a bottle/decant of this, please get some. It's a beauty and IMO none of the more recent PB's have delighted as much as this one did.
