Quantifying the Beyond Cold Blooded fleece I have

A wind proof fleece can basically be thought of like a typical softshell but with a soft face. They generally fit the same conditions – great around town and good for on and off levels of activity. Less good for consistent exertion.

Is there a way to 'puncture' the film to increase the CFM some? Maybe up to a 5?

you need to better qualify your statement. a non-membrane soft shell (stretch woven) has much more breathability than a membrane (windstopper or generic) fleece. my experience with membrane fleeces is that in most situations, they don't breath sufficiently to use them for anything except around town.

I see windproof fleece as a bad marriage of technologies. I agree onvthe softshell comparison, but it lacks the abrasion resistance and sucks up water like a sponge. It can be as heavy as soft shell, slow to dry, doesn't breathe at all, and is expensive too. A fleece and windshirt/rain shell are far more versatile.

Yes, but since I have already owned this thing for almost a decade I was seeing if there was a way to modify it some to get more usage out of it.

Run it through a sewing machine with no thread.

Stephen, Thou are a clever lad. Sewing machine as a "needle puncher". I used to see "Needle Punched" ski clothing in the '80s and even have an old Caribou Mountaineering (remember them?) winter sleeping bag with a needle punched mylar reflective membrane in between the layers of synthetic insulation. It actually worked fairly well.

Insul-Bright is a form or perforated insulation, commonly used for making lunch bags. I experimented with it for warm weather hammock underquilt insulation. It has potential. Something like a tattoo machine would do the trick :)

Yes, thank you for the ideas.

it will also work wonders on a not-so-tender hunk of meat (insert wink here).
