Built for fast movement in exposed terrain, the Senja Aero90 Vest delivers targeted protection where it matters most—shielding your core from wind while allowing heat and moisture to escape freely. Designed primarily for trail running but equally effective for any high-output outdoor pursuit, it’s the kind of layer you forget you’re wearing until the weather demands it.
The front panel is constructed from lightweight Aero90 recycled nylon, a tightly woven fabric engineered to block wind without sealing in heat. It maintains airflow to prevent overheating during intense efforts while remaining durable enough for repeated use in variable conditions. The back is built from an open recycled nylon-elastane mesh, maximizing ventilation and allowing excess heat to disperse efficiently as your pace increases.
Functionality is built into every detail. A slim, slightly extended fit ensures coverage without excess bulk, while elasticated arm openings and a high protective collar provide a secure, low-drag feel. Storage is intelligently designed: a zippered chest pocket and rear pocket work together, with the back pocket transforming into a compact stow system that lets you pack the vest and carry it around your waist when not in use. Reflective detailing enhances visibility, making it a dependable companion from early starts to late finishes.
