Favourite flavour
Big fan of SIS gels, helped me in many events, I’ve tried a number of them over the years but fruit salad is my go to! Tastes great, decent consistency so easy to digest on the move. Tried a lot of other providers but for value and taste SIS is one of the best
C**.
The best SIS flavour!
We all know that energy gels are usually not the easiest to stomach, but the flavour of these gels makes them easy to get down and keep them down! Will come back and order more. Only downside is that the price is a little high.
