If an ultra-light, breathable, hydration-compatible daypack is what you're after, look no further than the Mountainsmith Spirit 12. No matter if you're on a bike or on foot, the storage space for both your gear and hydration needs (there's room for a 100oz/3L hydration reservoir, not included) will make sure you're fully prepared for any all-day adventure. The Spirit 12 delivers comfort in spades, particularly via the Breezeway suspension system which pulls the pack away from your back and provides room for airflow between your back and the pack's back panel. The airmesh back panel and DWR anti-sweat shoulder straps provide additional cooling comfort while the sternum and waist straps ensure the pack remains perfectly positioned.
