"Bring everything you want on a chilly winter hike or a hot summer day inside the Gregory Jade 28 Backpack for Ladies. This voluminous daypack uses a dynamic FreeFloat system that moves with your body, preventing sore spots and giving you free range of movement. Open-air, precise-fit back panel with tensioned mesh creates an open space between your back and the pack to maximize ventilation. Designed around the architectural principles of tension and compression, the perimeter frame provides stable, yet flexible support to comfortably carry a full pack load. Torso provides 3.5"" of adjustment, allowing for a custom fit without compromising support. FreeFloat flexible, cushioned hip belt conforms to your lower back and hips supporting the weight in your pack while moving freely with your natural hiking motion. Constructed from Lifespan foam for lasting durability, the perforated shoulder harnesses maximize airflow and comfort on the trail. The Jade 28 women's backpack features a U-Zip front opening for full access to the contents of your pack. Extra-large hip belt pockets provide secure, easy to access to essentials like your phone.
