The weather has been cooling down a lot lately. And that might explain why Ornot is using Polartec for their new Alpha Wool Pullover. The new pullover takes Polartec Alpha, the insulation thru-hikers have been quietly hoarding for years, and blends merino wool fibers right into the lofted construction. It comes in both mens and womens cuts, and its made in the USA.(Photos / Ornot)Some of you may remember, but wool is the original cycling kit material because it adds natural temperature regulation and moisture management. A lot of times, cycling is just a series of easy and hard efforts over an expanded period of time. I mean, one minute, youre grinding up a climb, cooking like a rotisserie chicken, then next thing you know, youre descending into wind that makes you question your life choices. Most cycling garments with insulation nail one of those jobs, rarely both. But Polartec Alpha combined with wool can handle both: itll dump heat fast when youre working, stay comfortable when youre not.It Started with Thru-HikersThe platform underneath, Alpha Direct, started with thru-hikers. Thru-hikers will cheerfully trim a toothbrush handle to save a gram. And Alpha Direct is magically lightweight. Then, in comes merino, and you get added natural temperature regulation, moisture management, and a softness level Ornot swears will keep you from ever taking it off. (They claim to know this from experience. Ill allow it.)Wool in a performance layer isnt new, but blending it into Alpha for riding is a fresh idea. Its aimed squarely at the clammy-at-the-caf-stop problem that plagues plenty of synthetic midlayers.
