The Rab Men’s Protium 35L Hiking Pack has the largest capacity out of any Rab backpack built for day hiking. You can cram multiple layers and lunches for the whole family, or pack plenty of gear for more serious day missions involving summits and trekking through multiple altitudes and various environments. Its molded back panel provides enough support for a full day’s worth of hiking supplies, and it sits close to your body while maintaining enough flexibility for scrambling steep scree and fallen trees. Rab made the pack out of a Hydroshield-coated Robic ripstop for durability and long-lasting weather protection, and there’s a removable rain cover adding extra wet weather coverage. External attachments strap trekking poles when the going gets mellow, and there are pockets for snacks, gels, water bottles, and layers. Leave your smartphone in the pack’s internal pocket and keep your focus on the outdoors.
