Our heaviest weight base layer bottom in the Phase family, appropriate for cold temperatures and high output activities. Featuring comfortable anatomical shaping and mid-level insulation, these super-wicking base layer bottoms with through-the-crotch zip, which are compatible with the Alpha SV Bib CZ, are ideal for cold days in the alpine. Engineered for superior moisture management and rapid dry-times during stop-and-go activities, these form-fitting pants keep the user drier and more comfortable. Hybrid mapping of Phasic SV (in the body) and Phasic AR (in the panels) fabrics in addition to the flatlock construction and comfortable next-to-skin fit eliminates excess bulk and rapidly transfers moisture for efficient evaporation and improved temperature regulation and layering. Encapsulated silver-ion fibres provide durable and long-lasting odour control. Regular cut has 30̢? inseam.
