It has residual lanolin, but in modern times is sometimes treated with teflon or silicone treatments (if that's not for you, you can find untreated ones and possibly apply extra lanolin yourself). In my opinion, a cloak from that fabric should be superior to a home-felted swanndri. If you're interested, search for strichloden wetterfleck or kotze(yes, that means barf, but it's a cloak). There are various options, but they are pricy.
However, I've read opinions from german hunters who traditionally use this cloak. Some of them also do long distance hikes, and the opinion was basically - don't use it for that. It gets damp and cold, it gets heavy, it doesn't dry properly when it's wet all the time. It's great for a single day of hunting, but shit for multiple days of hiking. I assume that applies even more so to your swanndri.
