    Molly Mac Gear News: Mukluks & Anoraks

    I hope this is within the rules... just thought I would share two notable things that are happening with the mukluks and anoraks I am making. Today, I am making an Anorak for a fellow who says he is a "serious trapper" in Alaska. I send it to a Post Office box, and a plane delivers it to him...

    Custom Arctic Anorak, from MollyMacGear.com

    The ruff doesn't lay against your face... the hood extends out in front of you a bit. That way, you can pinch the wire in to narrow the hood opening when you are walking into the wind. The neck closes up as well, so that the ruff and your scarf make a wooly lining all the way around the opening...

    Custom Arctic Anorak, from MollyMacGear.com

    Hello, folks! I was just checking out the post Dave told me he made with my pics... wasn't gonna say anything, but ya'll are talkin' about ruffs, so I thought I would comment. My understanding and experience using a ruff in deep cold is that it goes on the inside, and can be folded to the...

    The Vapour Barrier Liner (VBL) thread.

    Heat is pretty much a constant for a living human. The colder it gets, the larger the differential, and the greater the driving force for heat transfer. Same with the humidity... pretty much constant high humidity at the surface of a living human, and extremely low ambient humidity in really...

    The Vapour Barrier Liner (VBL) thread.

    The notion that heat alone pushes moisture out is incomplete. It's the humidity differential , as well as the heat differential, that makes up the driving force. It is not just those driving forces, but also the resistance to heat transfer and the resistance to vapor permeability that control...

    Mors Kochanski survival scarf

    We make a Bivy Hammock that is a Mors Scarf. When Mors showed me his scarf, Jason and I looked at each other and said, "Gather the ends and that's a hammock!" www.MollyMacGear.com - MacEntyre

    The Vapour Barrier Liner (VBL) thread.

    Insulation does not have to be adiabatic (infinite resistance to heat transfer) in order for vapor to pass through without condensing. That is just what happens with a canvas anorak. It is possible that vapor condenses only to sublime immediately, but the effect is the same. I've never worn...

    The Vapour Barrier Liner (VBL) thread.

    I think we are both correct. The temperature and humidity gradients are controlled by the resistance to heat transfer and the resistance to vapor permeability of the material. If an insulator offers high enough resistance to heat transfer, and low enough resistance to vapor transfer, it will...

    The Vapour Barrier Liner (VBL) thread.

    I'd like to propose a different view of the technical aspects, and ask a question. Your skin has a high water content. In extreme cold, the ambient air has a very low water content. The difference between the high concentration of water vapor at the surface of your skin, and the low...

    The Vapour Barrier Liner (VBL) thread.

    I have had such great enjoyment in using traditional, vapor permeable, natural fibers that I just can't bring myself to try VBL clothing. Next month I will have a chance to listen to an expert while we all try to keep from freezing in northern Minnesota. Maybe I will learn something... -...
