Designed for running in extreme conditions, On Running's ULTRA is a men's trail pant made for competition.

Ultra-light and compact, this model benefits from high-performance technology thanks to its 2.5-layer waterproof design. This keeps you dry throughout your run, whatever the weather. If the weather warms up, simply fold them into a small mesh pocket at the waist.

In addition to the waistband, these pants feature lasticized ankles for even greater protection.
