The Borealis Backpack is a tried-and-tested favourite that transitions from forest trails to commuter trains with ease. Continuing the trend for ultra-versatile everyday packs, this new iteration converts from a daypack to a waist-fastening bum bag when you only need to pack light. When expanded to its full 17.5 capacity, it's roomy enough for extra hiking layers and a packed lunch or gym essentials, books and binders. There's a stretch-mesh water bottle pocket on the front, It features two external stash pockets, and there's a stowable hip belt that helps transfer the pack's weight from your shoulders to your hips. This season's model is made using recycled materials and features an extended bungee cord system for more external storage.
