This is an upscale designer sport water bottle, top of the line, and so much fun. The designs of all of Sigg's water bottles are gorgeous, from the plain, solid color bottles, to the ones with intricate designs.

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 less of a chore.

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. They do dent, but this only affects the outside, and I am told that for Sigg fans the light denting is more like a "seasoning" of the bottle (this is how I regard it); at any rate, my dents so far don't affect the inside of the bottle at all---they are just on the outside.

Sigg bottles come with several different types of tops. Although this sport bottle comes with a sports top, I didn't like it, so I bought the screw top. I don't like sports tops in general because you leave them on while you drink from them, and this one was no exception. All of the Sigg tops are interchangeable and if you don't like your top or if you want variety you can buy extra/alternate tops (from Amazon). The bottles are totally leak-proof with the screw top as well, which is important to me.

They are also 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.

This is a great bottle- weight, size, design, finish are all superb. Sport top is easy to use once you know how to use it (twist open and push down with a finger to start flow). Best alternative to Nalgene. I bought three and plan on owning them for a long time. 5 stars

This is a good light weight beverage bottle. I use it for carrying water to work and on my bike. The shape makes it easy to hold. The "sport touch" cap took some getting used to, but it works fine and doesn't leak. I wish it had a wider opening at the top though. It is difficult to clean unless you have a bottle brush. 4 stars

Sigg makes a nice bottle to hold your favorite beverage and not odors or flavors from the previous drink. The brush cleans it adequately and it is virtually leak proof. Love it! Only down side is that it is not insulated, so drinks get warm over time. 5 stars

first I purchased a 1L bottle. I loved it; however it was too large for me to hold while running. so I bought this one at .75L and it is the perfect size! Cool color too :) 5 stars
