SIS Shaker bottle for mixing powdered drinks
- The best bottle to use for mixing drinks, a must for Rego Build and Rego Rapid due to the whey protein
- This bottle is specially made for SiS, with handy markings that are a key part of the easy-mix system
- To use, start by adding drink powder up to the appropriate level, as marked on the bottle; then part fill with water and shake to mix the drink; finally top up to the final level with more water
- The result is no fuss, no mess, and less chance of contaminating your drink - assuming that you keep your bottle clean!
- A huge opening makes it the easiest mixing bottle yet to pour in powder from large tubs
