The Cotopaxi Allpa 35L and the OPPOSETHIS Ark - 2020 share similar territories when it comes to light-weight, durable, and purposeful backpacks. In their own areas of expertise, they've both gained a decent reputation among users. The Cotopaxi Allpa 35L backs it strength in terms of space optimisation, boasting 35 liters of capacity and a dedicated laptop compartment for a 15-inch device. Weighing 1.5 pounds, this robust model is made of 1680D ballistic nylon paneling and comes with additional items like a rain cover, laundry bag, and water bottle sleeve. Adorned with comfortable shoulder straps and an adjustable sternum strap, it presents an ideal choice for those who like some room to breathe.

On the other side of the scale, we have the OPPOSETHIS Ark - 2020. It's a little less roomy with a 25-liter capacity but it makes up for it with a more lightweight configuration, coming in at 0.95 pounds. A standout feature of this model is its laptop compartment that comfortably accommodates a 16-inch laptop. The Ark is made of an 800x600D lightweight, waterproof nylon-polyester blend that shouts resilience against elements while keeping things lightweight. Emphasizing organisation and easy access, this bag features a clamshell opening and minimalist design that fits into any environment.

Here's a quick summary of differences for your comparison:

-   The Cotopaxi Allpa 35L is larger with a capacity of 35 liters, while the OPPOSETHIS Ark - 2020 has a 25-liter capacity.
-   The Allpa's laptop compartment fits a 15 inch laptop, while the Ark can fit a 16 inch laptop.
-   The Allpa is made of 1680D ballistic nylon paneling, while the Ark uses a lightweight waterproof nylon-polyester blend.
-   The OPPOSETHIS Ark - 2020 is lighter, but slightly less airline compatible than the Allpa 35L.
-   The Allpa comes with additional utility items like a collapsible mesh laundry bag and a rain cover, while the Ark boasts a minimalist design that caters to efficient organization.

To me, it's not about finding the 'better' backpack, it's about identifying what suits your needs best. If having lots of space and extra utility items is your thing, the Allpa 35L would be a dream come true. For those who love a good minimalist design that features efficient organization and a touch of extra sophistication with its clamshell opening, the Ark - 2020 is a hard act to beat. Think about what you value most when it comes to your everyday carry. In a nutshell, both backpacks carry their weight with pride, echoing the call of modern urban activity with prowess and elegance.
