So this water bottle is supposed to me good for you, but I have to admit it kind of freaks me out. Sometimes my water has a metallic taste and the bottle dents easily. Still a fan of the Nalgene.

I love this bottle. Keeps my drinks cold and like it much better than my Nalgene (there isn't that plastic taste that always happened). Great buy!

Great water bottle. Good screw on top & keeps liquids cold or hot for a while. Can even heat water in it.

Yes they cost a lot. Yes they are trendy. Yes they dent. Most important they are good quality. I have had juice and tea in it and have no residual taste. My nalgene cannot do that. A lot of people hate them for being trendy, but contrary to what some of them say they are lighter than a nalgene (not that it matters). Also aluminum DOES NOT rust when it is dented. Don't know where that one came from. I have also heard concerns about how aluminum can leech dangerous chemicals into water. That is why sigg coats the inside of the bottles with a completely inert polymer.
Anyway, one of my favorite things about it is now that I spent that money on a nice bottle, I want to use it. All the time. I drink more water, less soft drinks, and waste far less bottles and cans. Dare I say this bottle has saved me money. Whether or not they are in vougue in the future, I hope sigg keeps making the best quality bottles money can buy.

I love these water bottles, they are handy, easy to drink out of, and durable. They can handle being dropped from some heights, with only minor damage. They never leak, and best of all are re-useable! No more wasted bottles everyday. Just refill and go!

I like the function of the bottle, the design, and the fact it does not leak. However, I took two brand new bottles on a recent backpacking trip to Ontario and performed a head-to-head comparison (Sigg 1.0L vs. the CamelBak Better Bottle w/ Bite Valve 1.0L) and found the CamelBak still looks new while the Sigg shows incredible surface wear from the inevitable drops onto rocks and use typical to the outdoors. The utility of the bottle is also limited because of the necessity to transfer water from a nalgene or CamelBak bottle to the Sigg bottle when filtering water with an MSR filtration system. Finally, I give the bottle a high rating because I feel that the overall function of the Sigg bottle has not been altered (according to the Sigg website the bottle liner is resilient to dents etc. and will not peel), it looks great, and the must-have factor is still seemingly high, BUT I would not purchase another Sigg bottle for use in the outdoors and my bottle may be relegated to my office.

Like most folks who like it outside, I've had both Sigg and Nalgene in my bag. I've settled on the Sigg. It's durable - Empty drop tests don't mean a whole lot. Dropped with the mass and non compressable nature of water the Nalgene bottle doesn't survive. The Sigg suffers large deformation, but you don't lose all your water if you happen to drop you pack off the ledge or off the top of a thrid world bus.
If you're a weight weenie, the Sigg is lighter. On my scale the Sigg is 141 grams verses the 175 gram heft of the Nalgene.
True the top is not attached with a lanyard, but I have yet to lose mine. My trick is stick my finger through the hole and wear the top like a ring while I am drinking. Reminds me of olf aunt Mabel's big gawty rings.
I've got a little .4L Sigg that I carry Rum around in. I recently washed it out and filled it with water. The bottle had no residuel run taste.
Bottle line - after using both, I'm sold on Sigg.

So I like the bottle. I like not having to worry about BPA. I like hearing a metallic *ching* when I put it down on the table. But...I hate how I can't fit ice cubes (or at least my freezer's ice cubes) through the neck. Thats the only advantage my Nalg has over this bottle.

I absolutely love having these Sigg water bottles. They are very handy and working around computers all day, its nice to be able to keep my drink on my desk rather then at my feet. With this bottle I know that I am guaranteed a great seal that wont fail on me. The only down side with this aluminum water bottle is its durability. These bottles dent extremely easily so be aware that if you drop them, bump them, or tip them over they do run the risk of denting.

My fiance bought this for me as a christmas present and I use it every day. I take it to work, the rock gym, and when Im lucky enough to get outside. Someone said its fragile, but mine has been bomber. I have a little dink from a far drop but it still works great. It keeps the temperature well and I have used it more than enough to warrant the price and will use it for years to come. I recommend. Big time.

Aircraft grade aluminum is really thin. I've dented two of these bottles, one of them to the point of unusability. I'm used to Nalgenes, but these seemed really fragile and dentable to me. The 2nd bottle dented just from being dropped onto the floor of the shelter.

I have a Sigg bottle with me nearly always. I own two 1.0L bottles, and they've served me so well that I buy them for gifts. Yes, they're slightly more prone to denting than a Nalgene, but they also have qualities that a Nalgene doesn't. The aluminum keeps hot liquids hot longer, and cold liquids cold longer. It can be placed near the fire for re-heats. I probably wouldn't boil drinking water in it, but I wouldn't be too afraid of putting freshly-boiled water in there. Might not be everyone's favorite bottle, but it suits me. Plus, the dents add character.

moved from Nalgene to this. like this a lot because of weight and overall slickness. dents easy but doesn't damage interior so far. a little pricey but so far worth it.

The water seems to taste better from this bottle!

Light and good quality!

If they could get the price down I would give it a five!

Bottle is very cool. I bought three.

Shipping was not good...all three bottles were in one box that rolled around, so bottles arrived a little dinged up. I started to ship them back...got sidetracked....used one of them...and never got around to returning.

Granted, this bottle won't fit an ice cube but it does a great job holding some serious BPA-free water. I use it at work and so temperature is less of an issue for me. It does dent if you drop it or happen to hit your co-worker in the noggin with it but the water inside stays tasting exactly as it should...like water. 'Nuff said.

I am able to put water into this bottle for drinking at a later time.

This bottle rocks the blocks off other bottles and is as light as a bladder without the worry of leakage.

Great bottle- water tastes great and stays cold. I would recommend getting the sport top.

Got the one with the red skull and it's attractive yet does the job. I dropped it while running and it got a ding in it but hey-it adds character. Environmental friendly and would recommend to everyone.

I purchased this bottle only to find that it was too large to fit into my cupholder of my truck. Furhermore, you cannot fit ice cubes into it because the spout is too narrow. On the other hand, I find it perfect for the office where the large diameter is not an issue. I purchased the 0.6L bottle to solve my problems in the vehicle.
Bottom line: I LOVE the concept of a re-usable bottle that doesn't alter the taste of the water or leach chemicals into it, but I found the 0.6L better suited to where I live my life.

The bottle works great, doesn't keep anything cold for long, but never leaks and Ive saved untold amounts of plastic bottles from heading to the landfill!

Great size. Can be placed in freezer. I prefer sport top (which you can buy and add to this bottle). Doesn't smell bad like plastic, easy to clean with a standard bottle brush. Rock out!

I love these bottles. With all that press about how even nalgene's leak plastic compounds, I decided to give these a try. True, they don't insulate what they hold, but if you drink as much water as I do, that's not too much a problem :)

so awesome! the water tastes SO good coming from this thing? how does it DO that?

Doesn't leak, stylie, and you use less plastic bottles.

I switched to the aluminum bottle because of the BPA that is in plastic bottles that leaches harmful chemicals. As a nurse I have researched it and it IS real. I have tried to eliminate BPA in my drinking bottles. These bottles are light weight, cool down liquids fast in the fridge and are stylish. I have gotten dents in them from dropping them, but they are durable and it does not affect the usage of the bottle. I am also loving that it doesn't leave any residual taste from having liquids other than water in them. I don't have to wash it very often! My only qualm is that the mouth is not wide enough to put ice in unless it is small or crushed. I put in the fridge overnight and it stays cool at work for hours, but as the weather gets warmer it does warm the liquid faster. I would recommend switching you nalgene for this bottle if you care about your health!

I love the looks of this thing. Lightweight, keeps water pretty cool. Screw-top cap was a little difficult to get on straight at times.

Can warm it buy the fire and not have to worry about melting the bottle. Just keep the cap away from the flame and it's all good.

Nalgene bottles are lame, get one of these.

I can't give this five stars because it is a pain to pack this around and it does dent easily. So, I probably wouldn't pack this around too much. I like it just for a jug to take to work. I have juice, milk, and whatever else in this and the smell/taste are gone with a simple rinse. That's why I think it is so great. It is also nice that it is BPA free, but there are a lot of other good BPA free options out there if you care.

I love this water bottle. I take it everywhere with me! The water tastes great coming out of this bottle.

I do enjoy drinking out of this bottle, the flavor is much better than drinking from plastic. The design makes sipping from it easy, compared to bottles with wide mouths. Don't toss your Nalgenes, use them to store dry goods, oatmeal, sugar.....

I love these bottles, as well as the Klean Kanteens. The upside to the Sigg's in my opinion, is the mouth and top. That indentation just below the mouth is where our lip goes, and makes for spill free drinking. This is a pretty small thing, but it actually makes a difference day to day.

With all the recent BPA controversy, I tossed my Nalgenes and tried one of these. I am really impressed. The perk is filling it up and putting it in the fridge, it cools down really fast and keeps liquids cooler longer. The same is true if left in the sun too though. Lightweight, no metallic taste whatsoever, and the 1L size is great for a day trip or running errands. No dents yet either.

Seems to keep things cooler, longer and water always tastes great. No plastic taste or excess flavor from previous contents.

I love the look - so much so that I bought one for my mom, mother-in-law, and stepmom for Mother's Day too. But we are all in agreement that we are disappointed that the opening is too small for anything but crushed ice. I have an ice maker with small ice but not even that ice is not small enough for the opening unless I push every piece of ice in the right direction and shove it down the hole which franky, I'm not going to do! Further, while my refrigerator ice maker makes crushed ice, the bottle is too tall for my ice maker opening so now I'm back to putting the crushed ice in another container and transferring the ice into the bottle manually.

Also, we have all noticed that the bottles loses its temperature very quickly. Maybe this is because of the amount that it sweats. If I fill my bottle and chill it overnight to drink during and after my yoga class, it not only sweats on the floor of my class but halfway through my class - around the 40 minute mark from when I took it out of the refrigerator - my water is room temperature.

I'm not giving up on Sigg though. I think I was drawn to the pretty design when choosing one and am hoping there is another Sigg out there with a bigger opening and less condensation.

The Sigg is undoubtedly a leader in the aluminum bottle world, but the 1.0L bottle does suffer from a few design flaws. As mentioned in another review, it does NOT fit in the cup holder in my car and the color on the blue maha that i received was streaky - which looked defective. On the positive side, the water tastes GREAT. However, there is a question of the leaching of aluminum into the water when using the Sigg to tote acidic drinks (juice, lemon etc.) and exposing the bottle to higher temperatures (outdoors, the car - in the sun?). I would like to see more safety testing on these aluminum/coated bottles. One alternative, the Laken brand bottle, does have test results on its website, and touts its own bottle as superior to the Sigg - with no leaching and with a mouth wide enough for ice cubes. They do warn against freezing the bottle or using it for hot liquids.

go with nalgene. sure these look hip and fun, but they are heavy, they dent, and they don't pack very well. and when they dent, they look like garbage and start to rust. contrary to nicole's review, the aluminum is a fantastic heat conductor, meaning your liquids match the outside temperature very quickly.
