Rab Men's Khroma Ascendor AS Pants

Size: 34

Lightweight and stretchy with impressive freedom of movement for tricky kick turns and steep boot packs, these breathable ski pants are perfect for spring ski mountaineering and touring.


When bitter winter winds abate, the snowpack stabilises, and big objectives come into condition, the Khroma Ascendor AS Pants come into their own. One of our lightest weight ski pants, they are built for the fast-moving ski mountaineer, setting out in milder spring conditions.

Built to offer complete mobility, stretch and temperature regulation on steep ascents and hours on the skin track, these ski pants are designed to keep you comfortable and protected. The tough, double weave Matrix™ has a brushed back making it soft on the skin or easy to layer over thermals. Shedding light rain, snow and offering wind protection, this fabric is also efficient at wicking sweat and breathing. Ideal for changeable spring days when you’re working hard at different altitudes.

Whether you’re sprinting to the summit for a timely, spring corn descent, negotiating a steep skin track or climbing on foot, these pants offer complete mobility. A longer length gusset crotch, articulated knees and stretch throughout, lets you tackle tricky kick turns with ease. Kicker patches protect from sharp ski edges and crampons, and adjustment at the hem allows you to fit them securely over ski boots. Equipped for both the up and the down, the Khroma Ascendor AS Pants are perfect for earning your turns this spring.
