800ml Sports Bottle

The 800ml SiS bottle provides a larger capacity for longer training sessions. Science in Sport describes the bottle as ergonomic and leakproof, with a standard diameter designed to fit easily into bicycle water-bottle cages.

The current SiS 800ml bottle is also listed as BPA-free and dishwasher safe.

Use with SiS Drink Mixes

The bottles can be used with water or prepared Science in Sport drink mixes.

The 600ml bottle is also a practical match for SiS BETA Fuel 80, which is prepared with 600ml of water.
