Colognes are very important for men. Like perfumes are costlier, colognes that are costly will last longer and those less expensive will last less long. Just decide how much you are willing to spend. Before buying cologne know about his taste and personality. If that person likes to try out new types of product then buy cologne that has a woodsy appeal. If you are very confused as to what type to buy see what he owns and purchase the cologne of the same brand. Before buying just check its smell. Smell should be something which the men will like and also which you will like, both are equally important. Before buying remember the age of the man. The older ones will like what they were wearing for years but the younger men like experimenting so buy more exotic and sensual scents. If similar aftershaves, deodorants and shampoos are found buy them as they are affordable.
