Pros & Cons

Pros & Cons

  • Due to their isotonic concentration, the SiS gels are quickly and easily absorbed by the body.
  • The SiS Go Isotonic Energy Gels can be taken without water or a sports drink. This makes them ideal during high-intensity workouts when it is difficult to drink large amounts of water.
  • The low concentration makes this gel suitable for cyclists with a sensitive digestive tract.
  • The tear-off strip makes the gel easy to consume while you're cycling.
  • Because of the rapid absorption this gel is less suitable for efforts which require long-burning fuel.
  • Texture can vary between gels, but fortunately this isn't an indication that the gel has expired.
