I didn't think I would care for this scent, but it's a refreshing beauty. The first notes are a blast of ocean, wood and greenery. If you sniff a bit deeper, you may pick up on the musky castoreum note, though it doesn't last long.
After an hour, it morphed into a watery woodsy mix with a hint of leather and sweetness. There was one odd note which I can only describe as Band-Aid. It may be from the leather mixing with the other notes which creates this, but it's a bit distinct.
As with the other Zoologist scents I've tried, Beaver only lasted 4-5 hours before becoming a skin scent. It does last longer on clothing, but for me, the notes are different when on my skin. Also, the sillage is on the lighter side. This isn't a beast mode scent and would be pretty unassuming making it great for all occasions.
