Keep up your outdoor interests and pass them on to your children. This is the philosophy behind Macpac’s Vamoose. Its sturdy construction and classic design will take you into the hills and over rough terrain with confidence. The Vamoose has a spacious 25-litre (1525 cubic inches) base pocket and a detachable day pack which can be used by you when you’re not wearing the carrier or by your little one when they get big enough to carry their own daypack.  The day pack can also be clipped to the shoulder straps and worn in front of mom or dad while they wear the carrier to even out heavy loads and help to make on the trail essentials easily accessible. And Macpac knows that outdoor families can't plan their lives around the weather so they’ve included the Sombrero Sunshade and Rainbow Raincover with this great carrier. It is available in two different sizes to ensure a perfect fit and serious load carrying comfort.  Size 2 accommodates torso lengths of 12-17” while size 3 accommodates torso lengths of 14-19.”
