Kyle this is one of my favorites of all time. I would agree on the staying power, but I live in the Houston area like you do and I often get a relapse of the scent on a hot, muggy, sweat dripping down my face day. You might see the Lime is used quite a bit more than the Spice.
I'm staring to investigate new scents and experiences with my shaving, and the Bay Rum strikes me as being a 'classic' in DE circles thus worth trying. However, I need to find a competitive UK stockist for the Bay Rum Lime Cologne. Can anyone point me toward either a stockist or a thread with the details?
