Review on 💧 Sigg WMB Sports Black Touch Aluminum BPA Free Water Bottle - 25oz: Top Choice for Sports and Active Lifestyles by Alan Miller

Very nice bottle and very functional, allows air into the mouthpiece when drinking. It's just aluminum, no insulation, but that's exactly what I wanted. However, I bought it thinking it would fit in a bike bottle cage, but unfortunately it's too thin to fit in a standard cage. I have no idea why Sigg didn't broaden it a bit and open up their market to thousands of cyclists (like me) who want an aluminum bottle and not a plastic one!
