The NEW Axis Straw Cap offers a spout that pivots on an axis to enable easy drinking from a range of angles. No tipping required! Cap is leak resistant when properly closed, with an easy one-handed open feature. When closed, spout lays in protective nest, shielding it for cleanliness. Featuring a dual action venting system designed to prevent pressure build up. The cap contains a silicone straw that goes directly through the silicone valve, so water does not come into contact with plastic while sipping. The pivoting handle provides a great way to carry the bottle and stows out of the way while drinking.
