The Dart Hydration Pack does exactly what its name suggests—it's all about quick, efficient movements to get you from A to B in the fastest time possible. This bag has been stripped-down to provide an incredibly lightweight but durable hydration pack with a 2-litre capacity.

The Dart has a snug, energy-saving fit that is very quick to adjust. The Quick-Flick buckles let you change the shoulder straps with just one flick. Keep your back cool and well-ventilated thanks to the optimised mesh system and rubberized mesh shoulder straps. The Dart also has bungee straps to provide easy storage and access. The hydration bladder is sold separately.
