Perfect
Fits perfectly in my Osprey day pack. It’s easy to fill, load in pack, holds more than enough water for long hike in hot weather, easy to remove, and to drain and dry. Very happy with it.

Sorely disappointed
I really liked this bladder at first, and had success with it for much longer than some of the other reviews on this page. Unfortunately, my bladder succumbed to the same issue that many people are reporting on here. This is an obvious design flaw in the bladder. I took care to treat mine really well, and all of the sudden found myself with two liters of water at the bottom of my pack. Could have done some real damage. I also find it really disappointing that Gregory requires that you pay to ship your equipment to their repairs and warranties shop. Many other outdoor gear companies will provide a shipping label for obvious warranty issues - and this is clearly something that would fall under their warranty.

I despise this water bladder!
I should have returned it when I had the chance. Instead, I thought I just didn’t screw the lid on well enough and then made countless other excuses each time it failed and leaked all over my pack. Maybe I forgot to close the bite valve… maybe I squished it too much… maybe that’s just condensation… Well, it failed again just recently when I was testing out my backpacking gear and got everything damp, including my camera. Never again will I buy this or any Gregory water bladders!!!

Best Reservoir Ever
Perfect fit for my Gregory pack, and the most thought out reservoir ever. So many useful features, and cheaper than lesser products, as well. Five stars all the way!!

Ripped after light use
I bought this 2 years ago and have maybe used it on 10 hikes. Went to refill it today and it had ripped where the cap meets the water bladder. Furious as this is the start of a 4 day hiking trip

Great Product!
Have always used Camelbak products (packs, reservoirs), but have been disappointed lately. After extensive research, I decided to purchase a Gregory pack for a 17 mile Sedona hike. The pack came with a 2.5L reservoir…which is fine for most hikes, but I wanted the 3L for Sedona. I was very happy with it. The size of the reservoir’s opening is generous and allows for easy filling with water & ice. And the location of the quick disconnect junction is absolutely perfect….so easy to access. I appreciated not having to feed the tubing back through the opening when I had to refill. Great product!

Best one I’ve had yet.
Perfect. Just what I needed. Best in the business. It doesn’t come with the magnet end that clips to the pack strap. You’ll need to buy that separate.

What is the extra magnet for?

how are you supposed to get water out of the bladder and tube to store?
July 15, 2022
Are extra magnetic accessories available (didn't see them on your website)? I use the reservoir with more than one pack, and it would be helpful to have sternum magnets for each.
