## Our thoughts

### Discover the Versatility of the Attitude Supply ATD1 Backpack

When it comes to minimalist travel, the Attitude Supply ATD1 backpack is an exceptional choice for those seeking both functionality and style. With its compact dimensions of 19.7 inches in height, 11.8 inches in width, and 10.2 inches in depth, this backpack is designed to be airline-friendly and easy to handle, yet expansive enough to accommodate all your travel essentials. Weighing only 3.3 pounds, it offers a 20-liter capacity that surprisingly expands up to an impressive 55 liters. This adaptability makes the ATD1 perfect for short trips and long adventures alike. The backpack’s compatibility with a vast percentage of airlines ensures that your travels remain smooth and hassle-free.

### A Smart Design for the Modern Traveler

Crafted from 500d, PU coated Cordura with a durable water repellent (DWR) finish, the Attitude Supply ATD1 is built to withstand the rigors of travel. This robust construction is similar to the renowned EVERGOODS backpacks, yet it brings its own unique flair to the table. The combination of bomber build quality and clever design elements makes this backpack an essential companion for any travel enthusiast. A review hailed its ability to seamlessly shift from a compact 20L to a roomy 55L capacity, declaring it an indispensable addition to any adventurer's gear.

### Features That Impress

-   **Transformative Capacity:** The flexibility to expand from 20L to 55L makes the backpack ideal for varied travel needs.
-   **Dual Opening Styles:** Both rolltop and clamshell openings provide convenience in accessing your belongings efficiently during different travel scenarios.
-   **Thoughtful Organization:** The front pocket is intelligently designed to keep your necessary items organized and within easy reach.
-   **Enhanced Laptop Safety:** The suspended laptop compartment is a notable feature, ensuring extra protection for your devices.

In conclusion, the Attitude Supply ATD1 stands out for its versatility and thoughtful features, making it a worthwhile investment for both day-to-day use and carry-on travel. With the added advantage of its distinguished construction and functional design, this backpack is set to make your travel experiences not only manageable but also enjoyable. Whether you're navigating through bustling airports or embarking on outdoor adventures, the ATD1 is ready to rise to the occasion.

## Our verdict

### Reasons to buy

-   The expanded capacity is superb at 55L. Extremely versatile to use as you can use it as a daypack or as your one bag carry-on travel.
-   Has rolltop and clamshell opening which are both convenient to use in different situations.
-   The front pocket offers great organization that keeps your handy things in their place during your travels.
-   The laptop compartment is suspended which adds extra protection for your laptop.

### Things to consider

-   Compression straps get in the way of the water bottle pocket when in use.
-   The bag doesn't stand on its own. This kind of complicates the use of the rolltop opening.
-   Quite heavy due to the extra fabric for the rolltop.

## What reviewers said

-   "The Attitude Supply ATD1 Backpack is very similar to EVERGOODS in terms of bomber build quality and functionality, but it morphs seamlessly between 20L and 55L. For me, that’s made it an essential"
