Instinct Trail Running Vests

Built for the Trail. Engineered to Perform.

The Instinct range covers every trail running scenario — from ultra-minimalist speed racing to multi-day alpine expeditions. Every vest is built around one principle: match your capacity to your distance, conditions and kit requirements.

The right vest is determined by three things: distance (how long you'll be out and how many aid stations you'll pass), mandatory kit (whether your race requires specific safety equipment), and conditions (whether you need extra layers, waterproofs or winter traction).

  • PX 3.1L — ultra-minimalist racing and training up to marathon distance.
  • Ambition 4.5L — speed and versatility for trail racing from 10K to 70K.
  • Evolution 7L — the ultra runner's workhorse for long-distance events from 20K to 100K+.
  • X 10L — built for mandatory kit events and winter racing from 50K to 100K+.
  • Eklipse 12L — mountain races and adventure days where weather protection matters. 360° water-resistant rear shell.
  • X8 18L — fastpacking and multi-stage racing where overnight kit must be carried at pace.
  • XX 20–24L — extended multi-stage capacity with adjustable volume for longer expeditions.
  • ALPI 40L — expedition-level alpine pack for serious mountain objectives.

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