Arc'teryx Phase AR Bottom -

Don't be a casualty to the cold. Pull on the midweight Arc'teryx Women's Phase AR Bottom for layerable warmth when cooler days arrive. Whether you're running wind sprints, chopping wood, or skinning up untracked snow, the Phase AR bottom has you covered. Constructed from two technical fabrics, Phasic AR and Phasic SL, this bottom excels as a layer during stop-and-go activities. Phasic AR fabric retains heat, while Phasic SL material in the panels provides an outlet for a surfeit of sweat.

A combination of flatlock seams and gussets behind the knee and in the crotch lets you move freely without high risk of chafing. The entire bottom contains encapsulated silver ions to reduce odor build-up, though the ions won't change the fact that you ate beans last night. Grab your ice-climbing pants, ski pants, windproof running pants, or jeans and get outside knowing you'll stay warm in the Phase AR Bottom.

FEATURES of the Arcteryx Women's Phase AR Bottom.
SPECIFICATIONS of the Arcteryx Women's Phase AR Bottom.

The Phase AR Bottom is a mid-weight base layer bottom that is appropriate for cooler temperatures, high-output activities. Composite construction of Phasic AR and Phasic SL fabrics in addition to the textile's construction and next-to-skin fit eliminates excess bulk and rapidly transfers moisture for efficient evaporation. Improved temperature regulation and layering.

Half-Moon Outfitters
These lightly insulated bottoms are engineered for optimal moisture management during stop-and-go activities. During active phases moisture is wicked across the entire garment, aiding temperature regulation. Entering a rest phase the broadly dispersed moisture evaporates quickly, speeding dry-time to keep the user warmer and more comfortable. Encapsulated silver-ions provide durable and long-lasting odour control.
