Review: Very happy with this, easy to use, works great! - I'm so glad I finally bought one of these. The large capacity and ease of hanging the bag to gravity filter is so nice. I used to go backpacking, get exhausted and sore from the miles and weight. Then have to go to the stream and fill a bottle and attach filter, squeeze and hold the bottles trying not to tip any over and spill as they slowly filled. Now I can scoop up a decent amount of water and hang it from a branch. Let gravity filter the water and have a hose with valve to control the flow. This bag system works great with my Sawyer mini and off brand filter. It is easy, clean, fast and packs up small and lightweight. I have bought a second one because it works so well.
Review: Good product - Purchased the 3L, used once so far. Easy to fill and hang, seems durable. No leaks. I easily attached my micro Sawyer water filter.

### ⭐⭐⭐⭐⭐ Good product
*by S***O on August 20, 2025*

Purchased the 3L, used once so far. Easy to fill and hang, seems durable. No leaks. I easily attached my micro Sawyer water filter.

### ⭐⭐⭐⭐ Waterbag that can reduce sediments
*by S***E on November 16, 2025*

Compared to other similar waterbags, the location of the exit port of this waterbag on the sidewall is more thoughtful: it is about one-inch above the bottom of the bag. This design can allow more sediments to remain in the bag than going to the filter attached, therefore, extending the life of the water filter. The 4-star was due to the plastic tube included. It will become very rigid in a cold environment (e.g., high altitude camping) and the water cut-off clipper will become useless. I solved this problem by replacing that with a silicone tube from a Sawyer gravity kit, which remains soft in cold weather.
