Question: does this have a chest,belly strap?
Document: Yeah buddy. coyote tan even matches my teeth. Smaller top to bottom than it looks on websites. In this case smaller is better.
This product kept me hydrated in a warzone and matched my coyote-colored body armor. Had enough capacity to get me through half-day or longer patrols in 120-degree weather, so I'd expect it would be more than enough for hiking around elsewhere.
The CamelBak Ambush is awesome. I work outside on a farm and wanted a way to keep water with me at all times without restricting my movement. I am able to easily drive a range of tractors and mowers without taking this pack off and the 3 Liters of water is just enough to get me through an 8 hour workday with cold or cool water. It is very durable and looks great.
Reviewing: Camelbak &#34;Ambush&#34;  Color: Coyote Tan. Review: Good quality! The color is dead on. If your not convinced, check out the reviews on YouTube!
I'm not sure what to do to get rid of the plastic taste in the reservoir. No instructions were included in that regard. Otherwise I really like it.
I was a big Camelbak fan while I was in the military (it was in fact where I discovered them). The Ambush is the perfect improvement over the ones were were issued. It is still small and compact, and the storage is just the perfect amount to take some snacks or small tools along without weighing down what is supposed to be a lightweight, compact water system. Quality is awesome. Well worth every penny. Very thoughtful design elements throughout. Buy it!
I purchased this for my normal 8-10 mile mountain bike rides. It is just the right size. I can fit an extra tube, multi-tool. CO2 carts, snacks, wallet, money, phone, and even have a little room to spare. The insulated hose is awesome and keeps water cool. My friend took one look and bought one of her own (in black - which looks equally cool as the coyote version).
I built an entire water filteration system on this platform. I got the Camelbak inline filter, iodine tablets and water filteration straw to attach to the mouth piece. Partner it up with Camelbaks UV water bottle so i can purify and screen the water some before i even put it in the reservoir. All together this is a great product and a strong platform to build on for emergencies or just everyday use just by removing the filters and storing everything in the pack.
