If you want a metal bottle, buy a Swiss made Sigg. I was a bottle tester for Sigg once, and I beat the ever loving hell out of the test bottle. All I could do was dent it a little.
The story: When I was in the outdoor recreation industry, our rep for the North Face picked up Sigg as a new product line. I was already on the pro staff for US made Ross Reels (a fly reel company), so he wanted me to try them out. I didn’t tell him I had had a Sigg bike bottle for years.
Rep: “Would you like a free Sigg bottle to test?”
Swag city.
Me: “Sure, but you should know that I can tear up an anvil.”
Rep: “You will love these. They are as close to bombproof as they come.”
Was he ever right. I still have the test bottle in the picture, and have worn some paint off it, but it will probably last longer than I will. At least it will keep me from being thirsty for many years to come.
