Keep active in the winter

The Winter Interactive Long Sleeve Base Layer is the warmest Assos long sleeve base layer. It accomplishes this by supplementing the SPC.07 fabric with the same warm, thick material proven to be so successful in Assos' previous generation frigid-weather base layer -- the Powerstatic Plus. The Winter Interactive has the same zippered, high-neck construction as the earlyWinter Interactive base layer. This neckline, plus the arm pits and backs of arms are made solely of SPC.07. The rest of the Winter Interactive is made from heavier, more-insulating fabric.

Assos suggests that you use the winter Interactive Long Sleeve Base Layer in conjunction with their airJack or fuguJack jackets, depending on the temperature. Assos recommends the Winter for temperatures ranging from 32-46 degrees. Available in sizes Small-TIR, in Black only.

One final note: Assos base layers are not specific to men or women. They are designed to be unisex.

As warm as they get

  • Familiarity: I've put it through the wringer

Older product that has been replaced with Assos Skin Foil designs that are apparently cheaper to produce. I haven't tried those yet but this base layer is VERY warm. I use it below freezing only. It is not windproof but the thicker material around the neck allows you to unzip when climbing and still not let in any cold wind. Very high quality durable fabric and construction as you would expect from Assos. The most expensive base layer I have ever bought, even when it was on sale. This layer extended the comfort range of my winter jacket another 5-8 degrees F compared to my heaviest Craft base layer.

Very good base layer

  • Familiarity: I've used it once or twice and have initial impressions

This base layer has an incredible fit, and feels like a second layer
