From the manufacturer

Elevate your adventure with the TWIST 600 Bottle + Bike Base (NEW). This sleek design uses strong magnetic force and mechanical latching to cagelessly secure bottle to bike. Our patented technology magnetically snaps your bottle in place and only releases when you give it a TWIST. Never lose a bottle on the trail again!

The new 600 Bottle uses softer material than the original, making it easier to squeeze.

Always BPA-Free & BPS-Free. Includes TWIST Bike Base and screws for mounting to standard braze-ons. Make sure to use the provided screws when attaching your bike base.
