Hello Lane,Hi Keyvan and @dan86 , Seconding you motions on the LEA Mentolada Cream. Works well alone and, like you, it's great when applied prior to my soaps to add some menthol chill to a shave.
Connaught also sells an inexpensive and overlooked preshave/postshave Noxema cream. It is a very interesting product with a nice amount of menthol. It is less potent than the Lea Montolada, but the menthol is still noticeable.
