Polartec® Thermal Pro® offers better performance than conventional fleece due to its unique construction. Insulating air cushions retain heat without restricting breathability. Open air channels in the material reduce dead weight and pack volume. prAna uses bluesign® certified Thermal Pro®, which is made from 75% recycled polyester.

Senior Designer, Eva Allison points out: “We love this fabric because it delivers lightweight warmth, so you never feel too bulky. You can layer easily under a hard-shell jacket and still have full range of motion.” She further explains: “The designs were kept non-fussy and simple to get more versatility out of the style. We want it to be a classic go-to-piece in the coming colder months.”

For women prAna presents the Tri Thermal Threads Pullover with a cozy hood and two zip pockets. The Tri Thermal Threads Tunic has a high collar and a longer cut than the Pullover. The Tri Thermal Threads Full Zip features a full-length front zipper.

The Tri Thermal Threads Full Zip is also available in a men’s version. The Tri Thermal Threads ¼ Zip sports a zip chest pocket, a high stand-up collar and a ¼ front-zip. The centerpiece of this range is the Tri Thermal Threads Overshirt with chest pocket, sporty collar and embossed metal buttons.
