I love this filtration system! It's user friendly and faster than pump styles. The amount of water you get from the bag is enough to do dishes and wash up a little plus put water in whatever container you've chosen

Used the Platypus Gravity 2 bag system this weekend, and it was great. So convenient. Having instant access to clean water without having to pump or wait drip drip drip for the gravity feed is a game changer. Can easily support 6 to 8 ppl.

This is the perfect water filter for small group backpacking trips. This filtered enough water for our group of 4 in under 10 minutes, hangs easily at your campsite for future use, and is easy to back flush (although rarely necessary).

I tried out my Platypus recently in Colorado back country and it works well. Sets up easy and water was ready in minutes. Back flushing the filter is just as easy. Also it packs up into a nice small roll. Happy with the quality.
Pros:
  • None
Cons:
  • 2 holes to hang look weak
Best Used for:
  • 2 people back country hiking
