Great
This hangs in my backpack with no leaks. I walk 5 days a week between 8 to 10 miles. I have the 2 liter bag and it is enough to keep me hydrated, l have had it for over a year and half and no problems. Amazon shipped on time and packed it good enough so there was no damage. Great product if and when it wears out I will order another one. I rinse it out every day and leave the cap open to dry it out. Once a month I soak with a tab of pepsident denture cleaner just to ensure no mildew buildup. Highly recommend.

Must have for longer hikes!
This was such a lifesaver on my hikes in Glacier! Love the easy fill twist off cap, and the handle to hold while filling up at fill stations. Definitely worth the money! I bought to go with my Gregory day pack.

Great bladder
Fits great in my pack. Nice that it came with the magnet and like the handle. Makes it very easy to fill without spilling. Wish the hose had a quick disconnect

Not worth money
I have several bladders but none of them fit my Gregory pack so ordered this Gregory bladder, it fits great but the cons include: hard to clean & dry out, opening is small, hard to add ice, haven’t figured out how to remove straw from bladder to clean

Broke too soon.
Bought in December 2024 hoping to use it for a trip to Sequoia National Park. When I got there in May of 2025 I was getting ready for a hike and when I poured water the base of the drinking tube had broken off. It was stored in the house and was under no pressure. Never used and not even half a year later it was broken.

Nice design
The design of this hydration bladder is good. Even little things like the handle for holding it to fill. Very well thought out and practical in every aspect. I recommend this product for anyone looking to buy a hydration bladder for hiking.

Very convenient when hiking

Purchased this item as it showed photos of the 3D version with the tubing disconnect, but despite the photos, it’s actually the non-3D version and missing quite a few features I was after.

The suction piece I got was extremely difficult to suck water out. Had to really use the suction at a specific angle whereas the 3L doesn’t have the same issue!
