The Instinct Trail Alpi 40 L w/flasks is a groundbreaking alpine vest pack that combines trail running ergonomics with the carrying capacity of a mountaineering pack . It is designed for trail running/hiking, fastpacking, ski touring and mountaineering – and is worn high and stable like a running vest rather than a traditional backpack.

This version comes with 2×600 ml Instinct Hydracell soft bottles , integrated into the front shoulder strap pockets for quick and efficient fluid access on the move.

With its evolutionary volume, the Alpi 40 can be compressed into a low-profile trail backpack or expanded for multi-day adventures , without compromising stability or freedom of movement.
