Features of the Thule Aion Backpack 28L Dark Slate
The travel backpack that adapts to your pace
The Thule Aion Backpack 28L Dark Slate represents the perfect blend of an everyday backpack and a weekend travel bag. With a base capacity of 28 liters that can be expanded to 32 liters thanks to its expansion system, it offers 15% more space when you need it most, without sacrificing its compact and stylish profile for everyday use. Its Dark Slate color—a sophisticated, deep bluish-gray—makes it just as suitable for an urban setting as it is for an adventure trip.
Designed and certified to the Bluesign standard, Thule guarantees that every component of this backpack has been produced in accordance with the highest standards of protection for workers, consumers, and the environment. The outer shell, lining, and mesh are made from 100% recycled polyester sourced from reused plastic bottles, making this backpack a responsible choice without compromising the premium durability that defines the Swedish brand.
Premium materials: P600 waxed canvas with a water-resistant finish
The exterior of the Thule Aion 28L Dark Slate is constructed from P600 waxed polyester canvas, a high-strength technical fabric that develops its own character with use and over time. This material features a water-resistant finish free of toxic PFCs, protecting your belongings in light rain or humid conditions without compromising the product’s sustainability. The texture of the waxed canvas gives it a rugged, slightly vintage look that sets this backpack apart from purely synthetic options on the market.
Measuring 28 x 23 x 47 cm (length x width x height) and weighing just 1.23 kg, the Thule Aion 28L is surprisingly lightweight given the number of features and the level of protection it offers. Its laptop compartment measures 40.1 x 25.9 x 2 cm, comfortably accommodating laptops up to 17 inches.
Smart Organization for Tech and Belongings
The Thule Aion Backpack 28L is designed for those who carry valuable tech and need quick, organized, and secure access to it. The interior design, featuring three main compartments, allows you to separate each type of item precisely:
- Laptop and tablet compartment: padded storage that protects laptops up to 17" and tablets up to 12.9", with dedicated space for cables and accessories.
- Removable TPU divider: separates dirty clothes, damp sports gear, or any odor-prone items from the rest of the backpack’s contents. Easy to clean and foldable when not in use.
- Top zippered pocket: keeps small essentials, such as your passport, keys, headphones, or chargers, safe and within easy reach.
- Quick-access exterior pocket: for items you need to grab without opening the main compartment.
- Interior zippered pocket: ideal for storing your phone, charger, and other small devices while traveling.
- Dedicated water bottle pocket: with an elastic design and pleated base, it holds bottles up to 1 liter and keeps them stable and accessible.
Suitcase-style back panel: full, hassle-free access
One of the features most appreciated by users of the Thule Aion 28L is its back panel, which opens completely like a suitcase. This 180-degree opening allows you to see and organize the contents fully, making it easier to pack before your trip and find items while you’re on the go. Internal compression straps keep everything in place during the trip, preventing the contents from shifting.
In addition, the backpack includes a rear slide-through panel that allows it to be slid over the handle of a wheeled suitcase, which is especially convenient at airports and train stations for those traveling with multiple pieces of luggage.
Compatibility with the Thule Aion Sling System
The Thule Aion Backpack 28L Dark Slate is compatible with the Thule Aion Sling (sold separately), an accessory bag that can be used as a hip belt to redistribute extra weight and provide quick access to essential items while traveling. This versatility makes the Aion the centerpiece of a modular carrying system designed for discerning travelers.
The backpack also features an exterior daisy chain for attaching additional accessories, such as a jacket, a bike helmet, or any other gear that doesn’t fit inside. The ergonomic, padded shoulder straps, along with the supportive back panel, ensure comfortable weight distribution even on long days.
Perfect for carry-on travel, work, and urban adventures
With its compact dimensions and a capacity of up to 32 liters when expanded, the Thule Aion 28L is designed to qualify as carry-on luggage on most airlines, eliminating the need to check bags on short trips. It’s the perfect companion for:
- Business trips and weekend getaways.
- Daily use as a work or school backpack with a laptop and tablet.
- City trips, day hikes, and outdoor activities.
- Traveling with a wheeled suitcase thanks to the pass-through panel.
