The Instinct Trail X – 10L w/Flasks in Black is a high-performance trail and ultra-distance running vest , designed for runners who need more volume without compromising stability, freedom of movement or fit. Developed in the French Alps, the vest is built on Instinct Trail’s philosophy of total freedom of movement and a second-skin fit.

With a pack volume of 10 liters, the Trail X offers space for all the equipment required during longer sessions and competitions: extra clothes, hydration, energy, safety kit, headlamp and poles. Despite the volume, the vest sits high and close to the body , which provides exceptional balance and eliminates bounce – even in technical terrain.

This version includes front soft flasks , positioned for quick and natural access while running. Instinct's smart pocket placement allows you to drink, eat and adjust your gear without breaking your stride . The vest is also compatible with Instinct's Ergo Quiver system for efficient pole management (quiver sold separately).

The fit is fine-tuned with side lacing in an elastic lace system in combination with adjustable chest straps , which provides a very personal and stable fit regardless of body shape, pace or load. The construction is non-compressive , which means that breathing and the chest are not restricted – a crucial detail for long distances. [polder.se]

The material choice consists of durable and breathable mesh , developed to withstand prolonged use in mountain environments while effectively transporting heat and moisture away. The discreet black color gives a timeless and functional expression , equally well suited for competition and training.
