We all know the importance of staying hydrated, especially during training or working out. The handy transparent water bottle from SiS is easy to take with you to the gym, work and school and fits in the bottle cage on your bike too. The SiS Bidon has markings so you can measure the exact amount of powder for shakes and is dishwasher safe so no hassle washing up. Also available in 400ml and 800ml sizes.
