The sun beats down on the desert landscape during your bike ride, making you feel even more dehydrated. That's where the Gregory Sungem 9 Backpack comes into play, with twin stretch mesh water bottle pockets on the back and a hydration port and sleeve for a reservoir. It also has a women-specific BioSync ATS suspension system that utilizes flexible material between the pack and shoulder straps for a more natural movement whether you're biking or running. The Aero-Mesh back panel moves cool air across your back to limit the amount of sweat collecting at your back for long-lasting comfort. And the main compartment has enough room for some snacks and your phone in case of an emergency.
