Thoughts on Insulation

post #1 of 4
Thread Starter 

What is going on with insulation these days?  The options for buyers are very confusing. With synthetics, there are at least a dozen different options I can think of (MIcropuff, Thermopuff, Thermolite, Thermoloft, Coreloft, MIcroloft, Heatflex, etc) all of which seem like some variation of spun polyester. The big clothing manufacturers are coming up with proprietary products but why? Is it to avoid the royalty fees or is it because the traditional  insulators (Thinsulate, Primaloft) are deficient. I have tried Coreloft and I wasn't overly impressed - I don't see where it is an improvement over the Thinsulate jacket I was using twenty years ago. Down is being pushed, but when I ski in down it seems to get compressed from sitting on the chairlift or from being under a shell and loses warmth by losing loft.  I find fleece to be good (also cheap!), but fleece can be heavy and requires layering which some don't like. Is there a best option in all this or is polyester polyester?

I like Capilene as a base layer. Non insualted shell jackets, and a light mid layer I carry in my pack in case it's a lot more stormy and cold up top. But I run kind of warm.

IME the synthetic fill stuff is all pretty similar, though I haven't tried all of the newfangled ones.  There's only so much you can do with spun polyester fiber.

2)  An /insanely/ fast-moving boom in micro- and nano-fiber development
