Like the earlier DSquared2 fragrances, He Wood Rocky Mountain Wood was developed by perfumer Daphne Bugey, and it is reportedly a "more virile" take on He Wood's "woody violet base note". I'll update with more detailed notes when I can find them.
DSquared2 He Wood Rocky Mountain Wood will be available in 50 and 100 ml Eau de Toilette. (via cosmeticnews)
Update: He Wood Rocky Mountain Wood was "inspired by the Canadian Rockies", and the scent is a woody vetiver with notes of mineral amber, incense, musk, Canadian lily, white pepper, vetiver and cedar. (via moodiereport)
