Great alternative to traditional CamelBak

If you like CamelBaks but get frustrated with mold and bacteria growing in the spout, this is a great alternative! It's easy to clean, easy to sip from (unlike those wide-mouth Nalgene bottles that cause you to spill everywhere) and doesn't leak.

This is my favorite pack out of all the CamelBaks I have tried.  I wanted 100oz bladder but not the big bulky size of the MULE and other packs.  This fits the bill.  It's lightweight, low profile, has great ventilation with the back air channels, and still has enough storage for a spare bike tube, pump, lube, multi-tool, camera, and wallet.  This will not work for bringing a big lunch or extra clothes or anything like that.  It's designed for being nimble with a large bladder, not carrying stuff.  Get the MULE or blowfish if you want to hike.

This Camelbak fit perfectly in a&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Timbuk2-Especial-Raider-Backpack-Black/dp/B00E1O4JE4/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Timbuk2 Especial Raider Backpack, Black</a>&nbsp;bicycle bag that I purchased specifically for hiking the Inca Trail in Peru. The material feels considerably sturdy and it was pretty easy to refill and clean. I don't mind that the tube isn't removable as I like that this bladder is low-maintenance. Dust would catch onto the bit valve but that wasn't a huge issue since staying hydrated is more important than tasting a little dirt on an amazing outdoor adventure anyway.

I love Camelbak's. My only complaint is that I wish there was a better way to clean and dry the reservoir bag and tubing. It's impossible to get all the water out of it! Otherwise, I love this bag. It's comfortable, durable, and light weight. Perfect for a day of hiking!

Love the new twist top Camelbak came out with. Super easy to open and close with your teeth while cycling so I don't have to use both hands.

For the price and quality, this can't be beat. It does what it says-it doesn't leak, hasn't broken despite dropping it multiple times, saves money on water bottles and reduces landfill waste, and has a good flow - especially compared to the CamelBak sipper. You do have to press the button down the entire time you drink, but that's where your hand would be putting pressure on the bottle anyway. The size is great and fits in most cup holders, including my car's abnormally small cup holders, and the clip is very handy for outdoor excursions. You drink out of this differently than most water bottles. Instead of rounding your lips, you flange them out a bit.

What I don't like is that for females, if you have lipstick or lipgloss (or even chapstick) on it tends to kind of "collect" on the seal-but is easy to wipe or wash off. I wouldn't recommend putting anything but water in here, because cleaning it after any sugar-based drinks would be more of a challenge. Also, this is a tad more obvious, but it isn't good for sodas because it's sealed so the pressure would build up.

Overall, this is my favorite water bottle, especially for errands and outdoor adventures.

Update 3/2012: We have since gotten rid of all of our Camelbak water bottles. Both Contigo water bottles we purchased are still going strong, despite daily use and multiple droppings (oops). It is dishwasher safe on the top rack, but we live in an apartment with a small dishwasher that won't allow it to fit on the top rack, so I hand wash them. I love that I can toss this in my purse or bag and know it won't leak. If you use ice in this bottle and the condensation bugs you, this sleeve does fit this water bottle, but the bottle can still rotate in the sleeve so you have to align it when drinking-not a big deal, but worth noting: http://www.amazon.com/CamelBak-Liter-Insulated-Bottle-Carrier/dp/B0019DCDIO/ref=sr_1_1?ie=UTF8&qid=1363328055&sr=8-1&keywords=camelbak+sleeve.

This bag was a drop in replacement for a 2L Camelbak bag that grew a bit of funk.

It held water just fine and the wide mouth made adding ice simple. The insulation wrap around the hose was a bit thin but it kept the first sip cool even in 88 degree heat. The couplers were leak free and carry handle was nice and sturdy for a 2L fill up.

The bite valve was a bit loose when i received but I resolved the issue with a pair of zip ties and it held up just fine for a weekend on the mountain. If you plan on using this bag it might be worth grabbing a hose clamp as the bite valve is press fit onto the hose.

Overall a great bag at a great price.

It seems kind of crazy to gush over a water bottle, but this one is great.  The CamelBak nozzle makes it virtually no-spill even when it's open, but still very easy to drink from.

Love this Camelbak hydration pack! Fits comfortably and securely. Has two smaller zip pockets which are perfect for keys, tissues, snacks, etc., as well as an exterior pocket for a small towel, snacks, etc. Highly recommend this pack for shorter hikes or bike rides!

CamelBak is a trusted brand in backpacking gear. Their walkabout bottle is very good as well. After so many washings you may need to replace the bite valves and straws.

I really love Camelbak gear, and this is one of their best. I especially love the quick release valves on both ends and the insulated hose. I'm thinking of replacing the 3L bladder in my Osprey day hiking pack with one of these.

It's essentially a super soaker squirt gun meets camel back but with a lot of extra conveniences. You could use it as a normal water pack and suck from the hose but it's not necessary if you pump it with air. Under pressure, you can squirt the water out and share or wash things. Clean up is a breeze as well. I had one of those camel backs but after use it was difficult to air dry without hanging it upside-down with some paper towels stuffed inside to prevent mold. This hydration pack is able to be turned inside out like a sock so you're sure all the nook and crannies are dry before storing. I took this water pack around the world and it performed flawlessly, especially in India where I paired it with the in line viral filter. Unfortunately, my day pack was stolen near the end of my trip in Spain along with the geigerrig so I ordered another one once I returned home. The new model has a better bite valve with extra flow that can be pulled apart for cleaning. Whenever I use the geigerrig, I always reminisce on that crazy trip.

Love the camelbaks, and this one keeps the water cold without sweating!

I won't get into the details; rather, Ill focus on what most people will want to hear.  I used a Camelbak Lobo for years.  It had several significant design flaws, starting with the poorly engineered reservoir.  I had to replace the cap o-ring like 4 times.  I spilled water in cars, backs... and all over myself, many times.  The reservoir was tough to clean and the mouthpiece degraded on a yearly basis.  This pack is much larger than a Lobo; it's more comparable to the Mule in the amount of storage space.  Yet, it is so comfortable.  It was not until I got this pack that I realized just how much better it is than the Lobo or Mule, starting with the amazing Osprey reservoir, which is perfect, in every sense.  The bag has a simple technology that alows your back to keep cool.  They've really thought of everything... I could write pages and pages about this.  I've used my Raptor about 10 times.  I hope that my initial impression holds after another 50 rides!

I replaced my Camelbak water bottles with two of these from Contigo. I like that they're glass and easy to clean with no mouthpieces to get weird or moldy! I don't hold the bottle by the strap--it seems like it would break if used this way. I wish it were a little shorter because it's difficult to carry in my purse, but other than those minor quibbles I'm very happy with both bottles. The other model I have has solid silicone with two long windows down the side, and I like it too--but this one feels a little more secure and easier to hang onto because more of its surface is covered in silicone. But it's also harder to tell how much water is in it. I would buy either model again.

I love this product!  Like all the Camelbak products I have owned, it works great.  It's so much easier to be able to disconnect the drinking tube from the bag for filling, emptying, cleaning, etc.  I like that the Camelbak stuff is made to get a few years of wear before it needs to be upgraded or replaced.  I just bought this conversion kit and used it on an old reservoir and saved a few bucks instead of buying a whole new reservoir with the Quick Link system already built in.  No other water reservoir system works as well as Camelbak, and I will continue to buy their products.

CamelBak Chute is my new favorite way to drink water especially if you don't like sucking on straws.  750ml is a great size and you can't beat the Red container with a Black cap.
