Women's Senja Flex1 Trackster Pants 25/26

Designed for trail running in shifting weather, these lightweight softshell pants offer the best of both tights and joggers—fitted where it counts, with enough room to layer underneath for colder conditions. They’re also versatile enough for hiking, fastpacking, and general mountain training.

The pants use Norrona’s signature flex1 fabric, a 125 g/m² woven double-weave softshell (86% recycled nylon, 14% elastane) with 4-way stretch. It delivers excellent wind resistance, high breathability, and lasting durability without compromising comfort or mobility. A PFC-free DWR adds light water resistance, while the bluesign® approval reflects a commitment to responsible production.

The technical fit is optimized for high-output movement, with articulated knees, an adjustable elastic waist, and zippered ankles with gussets to easily pull on or off over shoes. Reflective details and smart pocketing round out this mountain-ready design.
