Rated 5 out of 5 by from Exceeded Expectations I bought one for myself & one for my wife a few weeks ago. Day working on a ranch in Eastern New Mexico we didn’t want to have to return to the truck or a well every time we needed water. Both packs held up well over the course of the job.

Rated 4 out of 5 by from Works well I already have a hydration bladder in a backpack. But felt the backpack was to bulky for when I go riding my quad. So I had been looking for a smaller compact hydration pack. Didn't find anything I liked until , I went to the Camelbak site. Found the Ambush model, did some research. Then decided to buy it. I've only used it 2 times so far. I like the bite valve & dust cover combo. The on & off valve is nice. So I can shut it off after getting a drink. So I don't have to worry about it leaking out . Which I've had happen with my other pack (not a Camebak). My only issue so far is the chest strap. It cuts into my throat.The only way to stop this from happening. Is to tighten the shoulder straps up. This pulls the chest strap downward, away from my neck . But makes it a pain to take the pack off. I really don't want to use the plastuc buckles everytime to take off. It would be nice if the chest strap had more downward adjustment. Instead of being stitched into place where it is. I'm a tall guy 6ft 2in. Not sure if this has anything to do with how the chest strap is near my throat. Other than that,I like the pack alot. Doesn't hurt that it has 3 liter capacity. Would be great for bicycling , or hiking etc..

Rated 5 out of 5 by from Lightweight, Low-Profile, Built to Last Bought this CamelBak Ambush in Black as it is the same design as the issued USMC Hydration Carrier Pack and used the same Mil-Spec Antidote Reservoir 3L Short and now the new Mil-Spec Crux 3L Short Reservoir. Wanted something other than Coyote Brown and went with Black to match my CamelBak Stealth and CamelBak HAWG in Black that I also use. Love the shorter torso profile that this pack has over the other packs that use the longer thinner reservoir, but still carry the same amount of fluid. Other reviews I've read complain of a lack of waist strap/belt on this model. This is a shorter pack and if you put it on properly and cinch the shoulder straps correctly along with the sternum strap, it will stay put. If you need a hydration pack with a waist belt, get a longer profile pack that has it. Try before you buy. This pack comes with two outer pockets that can hold similar stuff you'd normally carry in your pockets i.e wallet, phone, keys, chewing gum, chapstick, lighter, compact digital camera, 2-oz bottle hand sanitizer, handkerchief, etc. If you need to carry more stuff, get a MULE or HAWG. In the back of the pack, there is a large pocket designed to stow away the shoulder straps if attaching to another pack or vest. You can easily put a poncho or light rain jacket for inclement weather. Previous versions of the Ambush had padded shoulder straps while this one they went with bare straps. I've used both models and can't tell any difference as the load weight is so minimal. If you need padding, others have added aftermarket shoulder pads that simply attach via hook and loop fasteners or just slip on. Easy access to the reservoir whether it be from the front flap for filling or the side zipper for the quick connect/disconnect for the hydration tube. Quicklink system allows for easy removal, cleaning or replacement of the mouth piece. Depending on the situation, I'll either have the Big Bite Valve Assembly with Cover on or use a Big Bite Valve Assembly without the cover.
