Exped Lightning 40

Exped Lightning 40 is a remarkably light trekking backpack that focuses on high carrying comfort through its adjustable T-Rex suspension. The roll-top design and smart compression let the load shrink down or expand to suit changing gear needs on multi-day hikes. With efficient weight transfer to the hip belt and reduced contact points against the back, it supports stable movement while helping airflow on warm climbs. Well-placed pockets and attachment options make it easy to separate essentials, wet items, and bulkier kit.
