SIS GO ISOTONIC CAFFEINE GEL

The SIS Difference:

What does isotonic mean? They are essentially equal in osmotic pressure and less likely to lead to stomach distress.

We know taking in carbohydrates with diligence can prevent bonking and improve endurance...but sometimes the high sugar content of gels can cause stomach issues. That's where the isotonic formula comes into play.

These gels don’t require you to drink water with them, making them a great option if you tend to experience that full, sloshy feeling from drinking too much water with your gels OR struggle with thick, syrupy gels. They also contain three different electrolytes to aid in proper fuel + fluid absorption.

The Caffeine Benefit:

Caffeine acts centrally on the brain to lower the perception of effort, which is particularly noticeable in longer events. In hard training and events over 90 minutes, mental fatigue plays a big role as things progress, in addition to physical.
