The HR Grommet is an iconic little adventurer. Crafted with elegant simplicity, it uses the comfortable and versatile EXACT FIT Mid harness, specifically designed to fit young people. The smaller back length and 45L volume make it perfect for school-aged children, providing support and healthy load carrying. It’s modelled on our larger bushwalking packs and uses similar features, so little groms can look up to the adults!

Crafted from lightweight, hard-wearing Cordura nylon, it’s easy to clean and long lasting, great for outdoor education fleets and the general rough-and-tumble of youth. Quality construction and design are used throughout, with reinforcing of the base, side pockets and other high-stress areas. This rucksack is simple to use: there are chunky, free-moving zips, big pockets for easy packing, easy access to water bottles, and more. We use non-crack side-release buckles, tough, chunky YKK zips and supportive, high-tensile aluminium frames for awesome durability.

Prepare for success with ONE PLANET outdoor education rucksacks, proudly designed and made in Melbourne.
