I like it very much. It kinda feels like a light MWF. It certainly loads really easily and lathers up slowly as you add water - it can take quite a bit of water and tonight I found myself dipping the brush three or four times, where normally one to two for face lathering. Post-shave feel is really nice - well moistured but without any mushiness and doesn't dry out after an hour or so.
I'm feeling that, but double tonight as my new favourite pre-shave soap is a rapeseed and goat milk from Ganders Goat. That soap is like a British "Marseilles" soap. The rapeseed is mega-feeding and almost uniquely similar to human subcutaneous fat. Pre-shave wash and then a good scrape with a razor, that pre-shave soap is felt well on into post-shave.
So, yes, between that and the donkey milk shaving soap, I'm feeling super-soft.
The Savonniere du Moulin was certainly trendy a few years ago, but they're still producing (so folks are still buying) and it's one of those soaps that I think is one you could keep for decades and keep coming back to it. Some eBayer in 2090 could buy a puck, like we do with '50s soaps and I'm sure it'll work as it does today. Mine came out of the loft following three or four years without use.
So, MWF light. Less chemicals ... in fact none, it's: "organic honey, organic propolis, flowers from my garden, good, fresh organic milk from my donkeys that I milk myself everyday, and lots of love" which is an ingredient list that makes for lovely reading.
English Shaving Company sell it, folks - both the unscented and a scented one, which is reputedly very light.
