One straw, four ways

Drink from the source — or bring it with you.

The straw works straight from a stream, screws onto any standard 28mm bottle, and integrates with most gravity bag systems. One filter, every situation.

  • Drink directly from a creek, lake, or puddle
  • Attach to a 28mm bottle (most water bottles fit)
  • Connect to a gravity bag for hands-free filtering
  • Filters >1,800 gallons per straw — no expiration
