Key Features of the Peak Design Travel Backpack 45L
Discover what makes this expandable backpack a game-changer for serious travelers
Expandable 35L–45L Capacity
The innovative expansion zipper transforms this backpack from carry-on compliant 35L to spacious 45L in seconds. Compress it for flights, expand it for gear-heavy days. This flexibility means one backpack adapts to weekend trips and month-long adventures.
Weatherproof 400D Recycled Nylon Shell
Premium 400D recycled nylon canvas with DWR coating protects your gear from rain, snow, and rough handling. The reinforced bottom liner adds extra durability where bags take the most abuse. Built to survive years of travel without showing wear.
Multiple Access Points (Rear, Top, Side)
Access your gear from three different entry points without unpacking everything. The rear panel opens like a suitcase for full packing access. Top zipper provides quick access to frequently used items. Side zipper lets you grab essentials without removing the pack.
Modular Internal Organization System
Peak Design's modular packing cubes and tech pouches attach magnetically inside the main compartment. Customize your organization based on trip type. The system keeps gear secure during travel while making it easy to find what you need.
Dedicated Laptop & Tablet Sleeves
Padded laptop sleeve fits devices up to 16 inches with separate tablet pocket. Both sleeves feature quick-access zippers so you can grab your tech at security checkpoints without digging through your entire pack. Perfect for digital nomads and remote workers.
Comfortable Tuck-Away Hip Belt System
Well-padded hip belt transfers weight from shoulders to hips for comfortable long-distance carrying. When you don't need it, the hip belt tucks away completely behind a zippered panel, creating a clean profile for urban travel or overhead bin storage.
360-Degree Grab Handles & Luggage Pass-Through
Grab handles on all four sides make it easy to lift and maneuver the pack from any angle. The luggage pass-through sleeve slides over rolling suitcase handles, letting you stack bags for easier airport navigation. Thoughtful details that make travel smoother.
External Carry Straps for Extra Gear
External compression straps secure jackets, tripods, or sleeping bags to the outside of the pack. Side pockets hold water bottles or camera gear. The versatile carry system adapts to different travel styles and gear requirements. Check our travel packing list for optimal packing strategies.
