Osprey Zealot 45 Climbing Daypack


All about this product



Designed with features that all climbers will appreciate, Osprey's larger Zealot 45L Climbing Daypack is made using Bluesign-approved Nylon fabric to ensure durability for scuff and scraps on a typical climbing day. The rope can be easily carried with a unique tarp to hold it in place, and the dual primary access allows for easy entry and cinch closure. External loops can attach items quickly and securely, while the compression straps keep everything where it is meant to be.

The EVA moulded back panel, and rigid frame ensures the heavy load is carried comfortably while maintaining stability. The array of different-sized pockets offers a simple solution for organising your kit, separating dirty equipment, stowing your maps away or storing your keys securely. The grab handles provide quick and secure shuttling to the next crag.

About this brand

A couple with Osprey backpacks walking up a rocky hill somewhere in the mountains.
Santa Cruz California 1974. Mike Pfotenhauer sat at his sewing machine with a head full of ideas and a burning passion to build the most innovative backpacks to the highest standard.


One man’s vision has grown into a wide range of Osprey rucksacks and accessories that are being used from the highest mountains to the most remote islands and everywhere between.


With innovation in every strand of each pack and an identity born out of true specialism, Osprey continues that true pioneering spirit today.
