Senja Flex1 Trackster Pant - Men's

What Our Gearhead® Experts Are Saying:

"I wear the Senja Trackster Pant on chilly morning runs and shoulder-season hikes—it moves like tights but feels like a softshell. Super breathable and stretchy, with enough room for a base layer if the temps drop."

Built to balance performance and protection, the Senja flex1 Trackster Pant is our go-to for fast-moving pursuits in variable conditions. Designed as a hybrid between tights and joggers, it delivers a secure yet unrestrictive fit, with room to layer underneath during cold-weather trail runs.

The flex1 soft-shell fabric is lightweight and weather-resistant, offering excellent stretch, windproofing, and moisture management. Its woven structure ensures durability for rugged terrain, while the 4-way stretch ensures you stay agile and comfortable mile after mile. Articulated knees and a tapered fit support natural movement, and zippered cuffs let you adjust the fit over shoes or boots.

Reflective accents boost visibility, and thoughtful pocketing—two hand, one mesh thigh, and one zippered rear—keeps essentials secure whether you're on the trail or the move in town.
