A lightweight men's backpack designed specifically for overnight adventures. We engineered the Big Agnes Prospector 50L pack in two sizes - men's medium and large - to ensure a perfect fit and maximum comfort on long journeys. Your pack should never be heavier than the gear inside, and this pack meets that standard. It features a compression - molded back panel, contoured shoulder straps, and a foam - padded hip belt. The unique Hoist Compression system pulls the load inward and upward, providing stability and comfort. With ample storage space and hydration compatibility, it's ideal for overnight trips. At Big Agnes, we've combined years of experience, ultralight materials, and advanced features to create a fast and light pack for overnight hikers, thru - hikers, and outdoor enthusiasts.

Enjoy comfort and support from the contoured, anatomically curved back panel with body - mapped foam, offering a precise fit and ventilation. The full - zip back panel gives duffel - style access to the pack's interior. The articulated Open Range Hip Belt ensures a secure and comfortable fit, transferring the load to the lumbar area with flexibility. The cut - to - fit hip belt wraps tightly around the hips, eliminating gaps. Dual hip belt stabilizer straps allow for a custom fit. Premium contoured shoulder straps come with an adjustable sternum strap and a hydration hose keeper. Load lifter straps help fine - tune weight distribution. The unique Hoist Compression system balances the pack's weight, pulling it inward and upward while securing the load. The cored aluminum perimeter frame, shoulder straps, and hip belt form an integrated suspension system, providing better balance on uneven terrain. Top - loading access with a roll - top closure and two side webbing buckle closures that adjust easily with the pack's volume. An internal 3L hydration bladder pocket includes a bladder hook, discreet tube routing port, and a hose keeper clip on the sternum strap.

Using Your Big Agnes Prospector 50L Backpack: First, choose the right size (medium or large) based on your torso length and hip measurements. When packing, start with heavier items at the bottom near your back for better balance. Use the compartmentalized storage to organize your gear. Put your hydration bladder in the designated pocket, thread the tube through the routing port, and secure it with the hose keeper on the sternum strap. You can adjust the shoulder straps, hip belt, and load lifter straps to get a comfortable and custom fit. If you're carrying trekking poles, use the webbing and bungee cord loops on the exterior. For ice axes, use the discreet loop. When closing the pack, use the roll - top closure and adjust the side webbing buckle closures according to the pack's volume. Attention: Don't exceed the maximum load capacity (18.14kg) to avoid damaging the pack and to ensure your comfort. Make sure all straps are tightened properly before starting your journey to prevent the pack from shifting. When not in use, keep the pack in a cool, dry place away from direct sunlight. Maintenance: After each trip, empty the pack and shake out any dirt or debris. If it's dirty, use a mild soap and water to clean the exterior. Avoid using harsh chemicals as they may damage the materials. Check the zippers, straps, and seams regularly for any signs of wear and tear. If you find any issues, repair them promptly to extend the pack's lifespan.
