Our Session series of bike hydration packs has become such a staple we’ve designed a model specifically for youth. This minimal, yet fully featured pack combines the cooling comfort of a breathable Air Flow back panel with breezy shoulder straps to keep you dry. The 100% recycled polyester construction makes it both lightweight and durable, while its narrow profile keeps the pack centered on your back.

The six-liter Session provides plenty of storage, including an exterior organizer pocket, a fleece-lined pouch for sunglasses or phone, a spacious main compartment for larger items, plus external attachment straps. On-demand hydration is delivered through a two-liter Hydrapak reservoir with drinking hose and Phaser bite valve. And the adjustable sternum strap features an integrated rescue whistle, so you’ll never lose your kid when they drop you on the trail.
