Great fragrance
Scent: Original Citrus + Eucalyptus
Took a chance and ordered this cologne for my husband without smelling it first. We both liked it (It's all used up- gotta order more:-) A light fragrance that lasts all day.

Every cologne certainly lasts differently….. just be aware
Scent: Original Citrus + Eucalyptus
Smells very nice like Harry’s Shower jell but doesn’t last very long at all on me , hopefully others so definitely not worth the money as far as I’m concerned
