The Katadyn BeFree AC 500ml Soft Flask and Water Filter fits neatly into your running vest or jacket pocket - delivering high-performance water filtration in a space-saving size. An essential for trail running, backpacking, camping or travelling abroad, it’s designed as an ultra-sleek soft flask with integrated water filtration technology.

This hydration system with 2-stage filter empowers you to fill from streams, taps or other sources and drink with confidence - filtering protozoa, bacteria, cysts and sediments while ensuring a fresh taste with the activated carbon pad. 

It’s capable of reaching flow rates up to 2 litres per minute to help keep refreshing hydration close at hand. A durable handle means you can use a rope or carabiner to attach it to your hiking pack for quick access to clean water. A sturdy flip cap offers leak-proof storage of your hydration even in challenging conditions. 

The advanced BeFree EZ-Clean Membrane offers easy cleaning of the water filter - just shake or swish in water to clear debris. With no extra tools required, you can enjoy minimalist camping with peace of mind.  

Key Features:

  • Lightweight Water Filter: 500ml volume - designed for minimal carry weight and maximum portability without compromising performance.
  • 2-Stage Filter: Combines a hollow-fibre membrane with an activated carbon pad to both remove microorganisms and improve water taste and odour.
  • Activated Carbon Pad:  Can be used when you want to improve the taste - even of chlorinated water - or removed when you’re accessing pristine water sources.
  • Fast Flow Rate: Delivers up to 2 litres of clean water per minute keeping you hydrated without delays.
  • Durable Handle: For convenient hanging from packs via carabiner or rope, or hand-carrying when needed.
