SIGG Lifestyle

Sigg water bottles are very popular with owners, who love the trendy colors and designs. Reviewers also like the lightweight construction, and they say that the water doesn't have a metallic taste. The Sigg Lifestyle collection comes in numerous designs -- new ones are added all the time -- and the Sigg Traveler collection offers more subdued colors and some textures. Sigg water bottles are made with aluminum, which requires a liner. In previous years, there have been some concerns about the epoxy resin liner in Sigg bottles, since most epoxy resins contain bisphenol A (BPA), a chemical that has been the source of much controversy over possible health concerns. To address these concerns, Sigg released a new EcoCare liner in January 2009, which is a baked-on polymer liner. However, Sigg still will not say exactly what it is the liner, so some critics fault the company for lacking transparency. Still, Sigg says that the liner has been tested and does not leach BPA or other chemicals. Durability may also be a concern, since numerous tests show that Sigg water bottles dent easily. The Klean Kanteen (*Est. $18 for 27-oz. bottle) is often regarded as a competitor to Sigg water bottles, although they are made with stainless steel, not aluminum. Klean Kanteen bottles do not require a liner, and the tests we've seen indicate that they are slightly more durable than the Sigg water bottles.
