Enduro Junior


Henty’s Enduro Junior is the ultimate protection and hydration pack for young mountain bikers.

The Enduro Junior has been designed to carry the essentials to keep you energized and hydrated whilst protecting the hips – a common injury zone, which no other product can comfortably protect. The water reservoir is positioned close to your natural centre of gravity, giving you freedom and agility while avoiding the sweaty bag you get from conventional hydration backpacks.

The Enduro Junior is the third generation of our game changing hydration pack solution, incorporating all the feedback we received on our initial release and the 2.0. Each Enduro Junior hydration backpack includes a 1.5L/50 fl oz HydraPak Compact Shape-Loc Reservoir, and a 90cm (36″) hose and bite valve.

The two sizes for the removable rear extension means the Enduro Junior now has more flexibility to fit a variety of body shapes, including children from six years old, women and men. The Enduro Junior is the only mountain biking hydration pack which you will ever need.

The Enduro Junior is supplied with the small harness which is designed to fit children from 120cm / 4ft tall and small frames up to 170cm / 5ft 7 and a maximum waist of 120cm 47 inches.

* The Large harness needs to be purchased separately and is designed to fit those taller than 170cm / 5ft 7.
