Increase your Osprey backpackAAAs gear-toting capabilities with the Osprey Daylite Backpack Attachment. The Daylite firmly affixes to all Osprey AAAAdd-OnAAA-compatible packs and then detaches when you need a lightweight and comfortable daypack for a summit push or a stroll around town. The rigid-foam back panel is covered in mesh and features a central air chimney to help circulate air behind your back, and an ice-axe loop totes your axe until you need to set an anchor or travel across a snowfield with a sketchy run-out.
