You may have noticed the Bolster comes without a heat proof silicon band. That’s because the Bolster is a double wall reusable cup that keeps drinks hotter for longer whilst remaining cool to hold.

Probably our most intelligent performer, the BYO Cup Bolster has all the other features you would expect – screw on lid and manufactured from tough BPA FREE, food grade polypropylene which is dishwasher safe. #winning
