This is an upscale designer water bottle, top of the line, and so much fun. The designs Of Sigg's water bottles are gorgeous, from the plain, solid color bottles, to the ones with intricate designs. They are simply beautiful! I switched from regular plastic water bottles because of health concerns, thinking it would take more work to maintain. These do necessitate regular cleaning (I clean mine every day), but having something so beautiful to drink from makes the cleaning fun. Sort of like my rings, glasses, and watch, I now consider my Sigg personal water bottle a vital accessory, reminding me to drink more water, making a statement about my values, and expressing myself with a special design. Yes, all in a water bottle!

Sigg of Switzerland water bottles are very high quality, made of light aluminum on the outside, slightly insulated, and covered with a special powder coat on the inside that prevents any leaching whatsoever, unlike plastic and polycarbonate water bottles. They are light, durable, and perfect for any activity. Well water tastes spectacular in these bottles, just like from the tap.

Sigg bottles come with several different types of tops. I bought the screw top because I don't like sports tops, and I don't mind unscrewing the top when I want a drink. It is totally leakproof, which is important to me. The top is pretty and can be hooked onto a carabiner. I get comments on it all the time, "What's that? I love it!" The sports top version is ok; I just am not a fan, as I don't feel like I can get enough water from the little stream from the sports top. However, for convenience, you might prefer it. For children, there is a cap-type top. All are leak-proof. If you are ever unsatisfied with the top, you can buy a screw top separately to fit your Sigg bottle.

Sigg makes their personal water bottle in .6L and 1L in this style. I have both. I use the .6L for sports activities because they are smaller. When I won't have to carry the container, I like the larger bottle. Sigg also makes a smaller .3L bottle for children that is a perfect size for young people. You can buy Siggs in alternative sizes too, such as .75L, .4L (for kids), .6L, .5L. You can occasionally find this bottle in the 1.5L size, also. Search Amazon for the perfect size.

Pick a style and pattern you like, as this bottle is a personal accessory, and should reflect your style. The colors are vibrant and even prettier than they seem in the pictures on Amazon.

They are expensive, but they are so durable that you can plan on them lasting many years. I consider them both an accessory and an investment in my health, so they are well worth it value-wise for me.

Highly recommended.

A great idea -- the water inside is always cool, the mouth of the bottle is designed perfectly to chug, and I never have to buy a plastic water bottle (which you're not even supposed to use more than once, but I often did) again. 5 stars

For the serious hydrator! I need to drink a lot of water throughout the day and carrying this bottle with me encourages me to drink and is great for my health and values. Plastic bottles are both unsustainable and can leach toxic chemicals into your water. Millions per year are never recycled (I've seen photos kids playing in a water bottle dump in Indonesia). This non-leaching bottle is attractive, sturdy and the mouth is comfortable to sip AND glug from. I fill it up from our high quality tap water and keep it around the house-- no more water glasses abandoned everywhere! I also feel great knowing I haven't put a dime of my money into supporting the public thievery that is the bottled water industry since I bought this bottle. I hope Sigg starts making these great large size 1.5 liter bottles again, I feel like stockpiling them for my family! 5 stars

...be forewarned if you drop your water bottle a lot (like me), it won't stay pretty for long. After just 1 month of owning my Sigg bottle, it was so dented up it looked like it had survived a war. The dents have caused paint to chip in some areas, and some sharp metal edges to protrude toward the base. Other downsides (in comparison to Nalgene) are the small cap loop for carrying, and the small mouth. But, the health/environmental pros probably outweigh these cons! 3 stars

Very sturdy and keeps fluids at the desired temperature for a good amount of time. I will buy two more as gifts for friends. 5 stars
