KEEP YOUR EXTRA ENERGY WITH YOU Sometimes when you are riding you need some extra energy. That’s why we invented the Energy Pack. It holds up to two energy bars or energy gels and fits perfectly at the harnesses of all of our Hurricane Rucksacks. The Energy Pack is made of a durable neoprene fabric and it closes from the top with velcro. From now on you always have your extra energy with you when you need it!
