Instinct Trail Running Vests

Built for the Trail. Engineered to Perform.

The Instinct range of trail running vests is designed for runners who demand more — from fast 5K efforts to multi-day ultras and mandatory-kit mountain races. Every vest in the range is built around a core philosophy: carry what you need, nothing more.

  • Ambition 4.5L — lightweight speed vest for fast efforts and short-to-mid distance races
  • Evolution 7L — versatile long-distance vest for ultra running and adventure days
  • X 10L — extended capacity for winter racing and mandatory-kit events
  • Eklipse 12L — ultra-distance and mountain race vest for serious alpine objectives
  • X8 18L — fastpacking and multi-stage racing with Cordura durability
  • ALPI 40L — alpine pack and trail vest for expedition-level days in the mountains

All vests include 2×600ml soft flasks and ship from the UK.
