I love Mama Bear's soaps, whether in stick, puck or teeny tiny baby puck size. Hers is the standard I use when measuring other soaps. Insofar as slickness is concerned, I don't need to lather for pass-2, just wet my face as the residual slickness is enough for me to shave with.
Note: I do lather for the second pass anyways
Mamabear soaps are fantastic! I will say that they aren't super slick but they give me a very comfortable shave every time! Top notch product made by a very charming woman.
