The Manta 24-liter is a premium hydration daypack designed to offer outstanding, fully-featured performance without compromise. Made to go the distance on your most committing hike adventures, it has loads of storage and organization, all packaged in top-tier sustainable fabrics. Gently used for a handful of hikes. Some dirt stains that should easily come out in the wash. Hydration bladder included! We loved this pack so much for day hikes. We just have kids now, so we're usually carrying them and don't need this anymore.
