A mid weight baselayer pant, with a brushed back providing quick drying warmth. Designed for use in cold weather with a slim fit; also great as a stand alone lightweight legging.

Rab says:

Take winter in your stride. With fast-wicking, high-stretch Thermic™ fleece and built-in odour-control technology, our new Women’s Flux Pant is the perfect midweight baselayer pant for hiking, trekking and cold days at the crag.

The Women’s Flux Pant is a comfortable, quick-drying stretch fleece baselayer for cold-weather mountain pursuits. Warm, breathable and easy to care for, it is built from soft Thermic™ single jersey knit fleece with a brushed back for outstanding comfort next to the skin. It also features a close fit with smooth flatlock seams for reduced friction under a shell pant during agile cold-weather ascents. The fleece wicks sweat fast, keeping you dry on the move and warm during rest periods. The wide, elasticated waistband also keeps the pants safely in position when you layer up and the integrated Polygiene® STAYS FRESH treatment reduces 99% of odour-causing bacteria, however many work-rest cycles it encounters.

While the Women’s Flux Pants are designed to help you move fast during winter in the mountains, they’re equally comfortable as lightweight standalone leggings for year-round use.

Rab's 2020 Womens Flux Pants are a mid- to heavy-weight baselayer and they provide quite a bit of additional warmth. With flatlocked seams throughout and elasticated fit waistband the Flux pants are really comfortable to wear - when its cold you won't want to take them off.The Thermic fleece fabric is soft and comfortable when on but the performance is particularly impressive as they wick moisture really well and are fast drying.

They are best suited to use as a baselayer for your sleeping bag in particularly cold conditions but they also work well under a shell pant in winter too.
