The Gregory Maya 18 backpack is a fantastic organizational backpack for the weekend day hike or bike ride. It is the unequaled companion for all your trail excursions. The Maya 18 by Gregory will carry all the things you need and can easily compress down when not full to keep the load centered and solid. The myriad of pockets helps to keep smaller things easily accessible. The Gregory Maya 18 daypack was made with women in mind, utilizing the totally new BioSync technology system. An aero-mesh back panel helps to keep you cool, and the hydration port and sleeve with tube system on the harness keeps you refreshed. The Maya 18 has an adjustable sternum strap for added comfort. The front expandable stretch mesh pocket makes it easy to stash away the extra layer you won’t need when the sun comes out, and the fleece lined media pocket keeps your new I-Phone safe and out of harm’s way. You have an interior mesh organizer pocket with built in key clip. The Maya 18 is pretty much the everyday go to bag for the girl on the go.
