The Cotopaxi Allpa 35L by Cotopaxi and the Deuter Aviant Access Pro 55 SL by Deuter are both distinguished choices when it comes to carry-on backpacks, though they cater to distinct set of needs. The Allpa 35L, measuring 20 inches tall, is in fact a lightweight cocoon for travel weighing a mere 1.5 pounds. It's compact yet surprisingly capacious with its 35 litre capacity. Vouched for by numerous reviewers, its selling points are its intuitive internal organization and the included set of handy utility bags: mesh laundry and nylon shoe bags, and a mesh water bottle sleeve. Allowing compatibility with 80% of airlines, it's truly a trooper to consider for those shorter trips.

On the other hand, the Aviant Access Pro 55 SL is the better choice if you're seeking a more substantial packing capacity. This Deuter backpack stands tall at 26 inches and contains 55 litres of space. Though it's a little heavier than the Allpa at 2.46 pounds, the superior capacity, the Contact Back system for weight distribution and ventilation, plus its NFC technology feature are compelling extras that might make the extra weight worth it.

Here are their contrasting features at a glance:

-   **Size:** Cotopaxi Allpa 35L measures 20" tall, while Deuter Aviant Access Pro 55 SL is 26" tall

The reviewers' quote paints the Allpa 35L as incredibly well-structured, a breeze to carry and perfect for both urban and outdoor travelers. On the other hand, the Aviant Access Pro 55 SL is appreciated by true nomadic wanderers. The former includes a rain cover and comes with comfort-enhancing straps.
