Designed for drinking This is not a redesign, it’s an evolution. The Series 2 range has been systematically engineered to deliver an unprecedented drinking experience. Still keeping your cold drinks cold for 24 hours, and your hot drinks hot for 12 hours. Anti-microbial & customisable The Series 2 Bottle is a triumph in reusable design. Its soft-touch, anti-microbial drinking collar ensures comfortable sipping, whilst its customisable carry loop makes on-the-go drinking even easier. And then there’s the rubber base, which proves it’s the little things that count.
