Sigg Water Bottles
Sigg water bottles are by far the most popular metal water bottles out there today. The most well known Sigg bottle is their aluminum water bottle that is coated with a special resin on the inside. The bottle itself is made from a single piece of aluminum, so it is a very solid structure. The resin was made to keep bacteria from growing in the bottle and make the bottle taste neutral. They claim on their website that the Sigg water bottle is resistant to fruit juice acids, energy drinks, alcohol and virtually any consumable beverage.
Sigg water bottles come in a variety of colors, designs, cap configurations, and other accessories. This is one of their biggest selling points. They are probably most known for their interesting designs on their Lifestyle water bottle collection. This collection was made for the person on the go, and has many choices to fit just about any personality. Some other companies are also putting out some designer style water bottles, but their bottles are stainless steel.
Overall, the Sigg bottle selection is huge compared to it's competitors. Then again, they have been making aluminum bottles for almost 100 years, so they should be the best. Otherwise, they would not be able to stay in business for almost a century. Aside from that, they have had the same amount of time to perfect their design and build their brand across the globe. They are even selling their aluminum water bottles in over 40 countries now. Sigg aluminum water bottles might be a lighter alternative to a stainless steel water bottle, but with stainless there is no need for a proprietary resin. The decision is up to you whether you want to go with a designer bottle with some sort of resin lining in it, or a stainless steel bottle that has no need for a lining.
