Multi-functional
lumbar packs, the Prowlers are ideal alternatives to
daypacks, especially when you need to get at the gear
inside without taking off a pack. Both the Prowler
(7.63 liters) and the Prowler .5 (3.61 liters) are
hydration compatible. The Prowler features an external
stow pocket and the Prowler .5 has an external shock
cord.
