With a body-hugging fit and contoured backpanel, the Gregory Maya 25L Daypack is custom-made for comfortable day hiking. The back panel features padded foam with aerodynamic grooves to promote airflow and all-day comfort on the trail. The contoured hipbelt supports day-hike-sized loads and features convenient pockets for easy access to our phone, snacks, and lip balm. The 25-liter capacity is perfect for extra layers, lunch, and all-day hikes and features a separate sleeve for our water bladder and a SpeedClip hydration hangar that's compatible with Gregory 3D Hydro reservoirs (sold separately).
