Daryl, I also have fur envy.
The closest I’ve found is the fabric Paramo use in the “Paramo Fleece” pieces meant to be combined with their “windproof” outer layers. When so combined, one has a waterproof system. A former Paramo employee later founded (now defunct) FurTech and explained best that Paramo works on a fur and feathers concept. The outer woven windproof layer functions like feathers, blocking wind and most rain and greatly slowing down any water that manages to press it’s way through the gaps in the weave. The inner layer, a light fur treated with Nikwax to be hydrophobic, is analogous to animal fur, and repels water in the same way – by reverse capillary action made possible by the combination of greater fiber density close to skin and less fiber density toward the surface, with all of the fibers being hydrophobic.
Paramo always combined these two layers in single garments, but a few years ago introduced these combo pieces. The fleeces in the Ostro, Enduro and Bentu lines are all made with a type of synthetic fur and are designed to be worn as standalone pieces. Unlike the very fragile “fur” inner layers of traditional Paramo gear, this fabric, which Roger Caffin described as “chamois-like,” is very tightly woven on its inner surface and furry on the outer surface, like the hair of a short-haired cat. The tightly woven face gives it pretty good wind-resistance, and also, combined with the fiber density gradient + hydrophobic Nikwax impregnation, very impressive water-resitance. My home testing shows that it is one of the very few garments available that have a combination of ~30 CFM air permeability and >300mm hydrostatic head.
Basically, it will block wind and breath like the vaunted “pre-2013 Houdini” and repel rain far better than most windshirts on the market. (That vaunted Houdini could only repel 70mm of water column, while this stuff can hold off over 300mm.)
I haven’t used mine that much yet, but really like the fabric. In Roger’s review on these forums of the Bentu, he mentions that the fleece is quite tough as well. I see these fleeces as a combination windshirt and heavy base layer and wear mine with a very light merino T, or next to skin. Unlike windhirts, this type of synthetic fur is soft and doesn’t make a whisper in the woods.
The worst thing about this fabric is that the density makes it quite heavy. A men’s M Ostro hooded fleece is about 13 ounces. So as well as providing as much weather resistance and insulation as the combination of a windshirt + heavy base layer, it weighs about that much too. Not to be left in the pack.
You can put it under the tap and water will run right off, like a good DWR windhishirt, but like those too it will also wet out if the water pressure is high enough. I haven’t tried petting it dry like you do with your cat, but will when I get a chance. I think shaking would be better, which we can’t do. Taking it off and whirling it round works with conventional fleeces, and I’ll give that a try with my Ostro too.
The Ostro runs slim, almost base layer slim. The Bentu (non hooded) fits more like fitted mid-layer. In addition to Roger’s of the Bentu, there are a number of Bentu, Enduro fleece reviews online that give good info.
