Our most technically advanced trousers ever are also the most comfortable. We’ve increased breathability with an Ultra Air-Flow design, featuring additional vents on the inner thigh to eliminate swamp-crotch, and using a highly breathable outer fabric to regulate the body's core temperature, keeping you in the performance zone longer.
Ultra Stretch delivers the greatest freedom of movement of any Zero trousers, with an improved 4-way stretch that works with the arborist in the trees and on the ground.
We’ve levelled up the durability with a new high tenacity ripstop nylon and supercharged Dyneema, and increased functionality with deeper pockets, an additional rear pocket, braces loops and velcro on the leg bottoms.
Finally, we’re introducing Ultra Connectivity. Every pair of Ultra trousers has a unique RFID identifier for asset management.
All changes come at no discernable additional weight, maintaining the Zero’s reputation as the original ultralight chainsaw trousers.
