Karbon Nitrogen Pant Full Side Zip Adult

Full side zips are the reason a pant like this gets worn instead of left in the car. A racer between runs needs to get insulated pants on over boots, quickly, without sitting down — and a pant that zips only at the ankle cannot do that.

• Full side zip for on/off over boots, and for venting
• Quadra Stretch fabric with Karbonite 20,000 waterproofing, fully seam-sealed
• Removable suspenders and adjustable waist
• Lightweight insulation

What 20,000 means: it is the waterproof rating in millimetres — how tall a column of water the fabric holds before it leaks. Around 5,000 is a fair-weather pant, 10,000 handles most days, and 20,000 is what you want for sitting on wet chairlifts and kneeling in slush at the bottom of a course. Seam sealing matters as much as the number, since untaped seams leak regardless of the fabric.

Pant or short? A full pant is warmer and covers the whole leg, which suits coaches and anyone standing still. A training short pulls on over a race suit and covers the thighs, which is what most racers actually want between runs.

There is a junior version of this pant.
