I was very happy to be asked to provide a review of Moon Soaps Old School, especially since I'm more of the "blade guy" around here with all of my trials and reviews of blades. I've never been asked to review a soap, so this will either be quite interesting, or quite maddening for the rest of you. Here's hoping for the former. Quick disclaimer - I have no interest in Moon Soap other than being asked to do this review. They sent me a tub of Old School and a sample of Havana, and asked for nothing in return except an honest opinion and review. Well, honesty I'm pretty good at. So no worries. I decided to do a review over four days of shaves in order to try all four types of brushes common to us all. I'll start with synthetic, then badger, then boar, and finally horse. I'm looking for ease of lather, amount of lather produced, slickness and protection, and after-shave feel. This first review will probably be the longest of the four since I won't have to elaborate quite as much as I move from brush to brush. I am also going to use the same razor and blade on each shave, and in order to judge slickness and protection I've chosen the Feather DX pain stick and Feather Pro blade. Since it's in the straight razor family, it was suggested by @wristwatchb that this could be a "Dark Side of the Moon" shave. I'll just leave that right there. Here's the gear. The brush is the Jayaruh #54 with Maggard knot. Definitely one of my top synthetics. So, to work. First order of business, the ingredients and scent. Moon lists the ingredients as follows: Water, Beef Tallow, Stearic Acid, Castor Oil, Mango Butter, Glycerin, Shea Butter, Potassium Hydroxide, Almond Oil, Sodium Hydroxyde, Fragrance Oil Scent: Tobacco, Vetiver, Leather, Mahogany, Sweet Vanilla I noticed that @Primotenore mentioned the Coconut oil that is prominent in the Havana. None of that here. I'm a tallow guy too, so I'm loving the look of that list. The addition of some extra oils and butter products also leads me to believe this will be pretty luxurious, or at least should be. As for the scent, I rather like it. It reminds me a bit of Haverford from Stirling. The tobacco and vanilla notes are obvious, but not as strong as the Havorford. I can pick up the vetiver adding some mildness to the stronger scents and the mahogany seems a bit faint but definitely mellows the vanilla and tobacco. It's a fairly light scent, but very nice. My wife approved, though she had trouble with picking out the scents. An hour after the shave the scent is still faintly noticeable, but an after shave would likely not conflict with it. I am a dedicated face latherer so the first task at hand is to load the brush. I soaked the knot for about 30 seconds, which is plenty for a synthetic, and started working on the soap. It's a soft soap so should load easily. And, after about 30 seconds, this is what I had. That should be plenty to get me through the rest of the shave and experiments. As I mentioned, I'm a dedicated face latherer. So the next step? Why, bowl lather, of course. Let's see if it can respond to my attempts at something I do very rarely. Here's the final result. Not bad, if I do say so myself. I did have to add water twice to the bowl as I worked it up and the soap seems to be just a bit thirsty. It definitely took more water than Stirling to produce that kind of a lather, but it wasn't difficult to get it there. I added slowly and it could probably take a bit more without a problem as well. Now, for fun, let's hand lather to see how it holds up. Nice rich lather with a few small bubbles here and there. Notice in the center the density of the lather, though. This seems to be quite slick and protective at this stage. So, now that we've emptied that much out of the brush let's face lather and see how it does with that, as well as if there's enough left to make it through the entire shave. I'm not one to overdo it on lather, preferring the "snowman" look that Geo Fatboy talks about. No problems there. Plenty of lather, and the coverage was very good. I wondered, though, how it would hold up as I went through the shave. Well, nothing to do now but shave. On my first pass I could tell the slickness was quite good. I was a bit concerned about that as it has a bit of a "sticky slick" to it. That's where adding a bit of water could help. However, there were no issues on the first pass and on the left side of my face the lather which had been waiting on me as I completed the right side was just as thick and slick as the right. Very nice performance, especially since pain stick shaves are slower for me as I take more time. I lathered again and got the same good coverage, only this time I had dipped the brush tip in water before going to the face. No "sticky slick" this time....just SLICK. And protective. I did an XTG pass with no problem at all. The razor was gliding and cutting with no issues. I rinsed, again dipped the brush for a second and did my final lather. The ATG was also effortless and I finished with a near-BBS result. What I expect out of a pain stick. Now for the acid test at the end....irritation. Did the Old School protect from irritation? Alum says yes. Only one hot spot near my goatee which is fairly normal for a pain stick shave. Other than that, no problem at all. It has now been about an hour since the actual shave and my face still feels smooth, soft, and very nice. There's clearly a lot of tallow in this soap and my face loves it. No complaints there at all. I have to say I'm pretty impressed and very happy with how this soap performs. It doesn't seem difficult to lather at all with a synthetic and definitely provided the slick and cushy properties I value in a soap. I am curious how long the 6 ounce tub would last and may have to spend some time working on that equation. At $17.00 per tub it's not outrageously priced for 6 ounces and if it provides excellent longevity could be considered a bargain for those who enjoy it. I'm not ready to rate it completely until I run the other brushes through it, but I'll do that in the next three nights, share the results, and provide a summary at the end. For the first night, though, and the first time I've used this soap - I'm giving it a thumbs up.
