LEAT F4 HYDRATION SYSTEM (1 von 1)-2

Jury Verdict

The Leatt F4 Hydration system rucksack is based around the x-shaped No Dancing Monkey harness system developed by USWE. As a result, the well-made backpack differentiates itself from the competition not just in looks, but also with the impressively secure fit and outstanding comfort levels. Once you have set up the effective size adjustment, you are free to hit the wildest trails and jumps with the stylish and compact F4 pack – you’ll almost forget it is on, as nothing can make it budge. The well-executed 3-liter bladder system and sufficient options for fixing helmets and protectors make the F4 Hydration System ready for every type of bike adventure. An absolute best buy!
