Question: Does the bag give the water a plastic or chemically taste?
Document: While not the cheapest alternative on Amazon, this hydration bag is better than advertised. Quite thick (not likely to get accidently punctured) but still pliable plastic resevoir, super easy to fill and even better, very easy to dry out between uses. No nasty taste to the water stored inside, and a great cover--with a dummy cord so you won't lose it! !--for the mouthpiece is included. All in all, I like this better than my husband's Camelbak resevoirs.
If the plastic taste that the name brand hydration bladders impart to your water annoys you, then here's your answer.
A very good product and I can only recommend it. It is easy to fill, empty, clean and use. The pack doesn't have a funny smell and the water is tasteless (no weird plastic taste or such). It kept us hydrated throughout the day and it was awesome to not always have to take out our water bottles.
I have looked at a lot of different Bladders and this one seems to work best for me. The water tastes clean with no plastic taste. Its easy to clean. Very easy to drink from the tube. I purchased the 2 liter for my Osprey day pack. I am very happy with my purchase.
I own two of these bladders for my hiking backpacks and have been very satisfied. The novel opening design really does make cleaning much easier and the bladder and tube material don't add a plastic taste to the water. The taste difference is noticeable enough that I threw out my camel back after I bought the first Source reservoir.
The Source 2L Hydration System comes with everything you need. The bladder and hose are included in the package along with a little cap to cover the mouth piece. Upon arriving, I wanted to test out the product to make sure there were no leaks and that it worked properly before taking it out for a hiking/camping trip. I have to say, every review I read highly rated this hydration system and I can see why. The bag is made of a thicker plastic-like material which is plenty durable.
I use this for backcountry skiing. Makes it easy to sip while climbing without unpacking a bunch of gear and making your buddies wait for you. It doesn't taste like plastic either. Very easy to use and clean.
This seems better than my old Camelbak bladder. I still use the Camelbak backpack though and this model fits just fine. It doesn't leak or taste funny and is pretty easy to clean and dry (the whole top folds over and is held in place with a sliding plastic clasp so the bladder has a big &#34;mouth&#34;).
I used it for 5 days of hunting  in Montana last week. Water tasted like water and not plastic. Thanks!
It's easy to fill, has both a bite and turn nozzle, and the water flow was just fine. I have yet to use it out on the trail, but will be doing so soon and will update this post after. So far, I would give this a 5 star rating and would definitely recommend this to anyone looking for a hydration system that is durable and an overall good product.
