The Sigg Active Top Dynamic 0.75L Aluminum Drinking Bottle features state-of-the-art engineering with pressure-relief valve and pre-ventilation system that are just some of the technologies integrated into the New Active Top bottle-closure system. The integrated straw gives you easy access to your beverage, without having to lift or tilt your bottle. The new top is also leak proof – even if you turn the bottle on its head – which is great for all athletes, drivers and kids. With this top, having to unscrew your bottle is a thing of the past, so you can simply reach for your beverage whenever you get thirsty – without taking your eyes off the road and without the risk of spilling. Stay perfectly hydrated with the new SIGG Active Top collection. This 0.75-liter SIGG Dynamic White Touch aluminum water bottle has a highly resistant BPA- and phthalate-free lining, making it almost unbreakable!
