Since the time we got our hands on Bobble's active filtering plastic-made water bottles, Sigg has introduced its new aluminum made, durable water bottles featuring a new smart drinking system Sigg calls Active Top. If you ever considered getting yourself a reusable water bottle, suffice to say you're familiar with this Swiss household name. Sigg has started the metal bottle revolution with its original aluminum bottles that featured the iconic screw-in loop bottle top designed in a way that lets hikers and mountain climbers attach their bottle to the rest of their gear using a secure carabineer clip. The new Active Top equipped Sigg bottles bring an even easier and secure way of drinking while at the gym, work and out in the great outdoors without taking your eyes off the prize.
