Camelbak Omega Water Reservoir (100oz)(OLD)

More than a Backpacker's Big Gulp
I like big reservoirs for the varied capacity that lets me choose how much water I want to carry, but on a recent trip we discovered another huge benefit for the 100-oz. and 70-oz. Camelbak Omega pouches. The weather was hot the day we packed, so I had preloaded the reservoirs with plenty of water, but the trip up the mountain was overcast and no one drank as much as I anticipated. This wasn't a bad thing because when we arrived at camp our water source (an alpine lake) stunk like dead fish and there were warnings posted everywhere for giardia. We had purification filters for pumping, but no one really wanted to sample the lake water unless we had to, so we used the combined contents from our Camelbak reservoirs to drink, cook, clean and sip throughout our overnight stay. There was more than enough water left for everyone to re-hydrate after killing off a bottle of wine and the next day we made it to another (far more fragrant...) water source without running dry. Keep in mind that the 100-oz. size is a little tough to fit inside compact daypacks with smaller (and older) hydration pockets, so if you have doubts check your pack or consider scaling down to the smaller capacities.

Easy to clean
Good product the big opening makes cleaning easier and more complete.

A very good reservoir
I used to be a 100% Platypus user but I find myself replaceing the worn out bottles with Camelbak's softer polyurethane pouch. When new, the Platypus works just fine but after the 2nd or 3rd year of use, the stiff plastic can wear at inadvertant folds that develop with use. This results in pinpoint leaks that have to be repaired with some type of tape in the field. Camelbak's softer polyurethane pouch flex better. I always prefer to get the largest volume possible so I can have extra reserve water. I use the screw-on top just for refilling from a potable water source such as tap water. In the field, I pop off the bite tip and attach the tube to the outlet of my water filtration pump.

beautiful
really cool..only problem is if the reservoir is higher that you (ie, in the top of ur pack) gravity will work its magic and all the water explodes out of the straw and its hard to close..so just a word of advice

Great, but be aware!
I was very happy with me new camelbak reservoir, it was almost a love affair. Last january I went to climb in Ecuador. Climbing Cotopaxi (5897 meters) my camelbak tube froze, so I had to make it to the summit and back again without a sip of water, not a nice experience. So be aware, that reservoir is made for cycling not climbing, and will freeze with ease in below zero (degrees celsius) temperatures.
