Cotopaxi Allpa 35L vs. Atom Packs "The Atom"

In the world of carry-on backpacks, both the Cotopaxi Allpa 35L and The Atom by Atom Packs stand out as high contenders. Constructed from a robust 1680D ballistic nylon paneling, the Allpa boasts a spacious capacity of 35 liters, and measures up to 20 inches tall, 30 inches wide, and a hefty 51 inches deep. In contrast, the leaner Atom, crafted from sleek, ultra-durable VX07, offers 30 liters of space, and stands at 45 inches tall, 24 inches wide, and 18 inches deep. Despite the Allpa's larger size, the Atom boasts a higher compatibility with airlines, compatible with 84% versus the Allpa's 80%.

• Cotopaxi Allpa 35L: 20" tall, 30" wide, 51" deep, 1.5 lbs, 35L capacity, 80% airline compatibility, made of 1680D ballistic nylon paneling, fits 15" laptop.
• The Atom by Atom Packs: 45" tall, 24" wide, 18" deep, 0.4 lbs, 30L capacity, 84% airline compatibility, made of VX07, lacks laptop compartment.

Reviewers commended the Allpa 35L for its ideal blend of functionality and simplicity, largely due to its intuitively designed internal organization. It doesn't skimp on comfort, either, with plush shoulder straps and an adjustable sternum strap offering just the right fit. However, critics were similarly vocal in their praises for The Atom, recognizing its suitability for those preferring minimalistic and streamlined hiking gear, built with a significant emphasis on quick and easy access to essentials.

Final call? The Allpa 35L, thanks to extra features such as the rain cover for protection, comfortable straps, and a variety of helpful add-ons like mesh laundry bag, shoe bag and water bottle sleeve, is a perfect pick for novice travelers looking to embark on their journey with ease and style. The Atom, on the other hand, is best suited to the seasoned hiker who values lightweight durability, generous, accessible storage, and has a fastpacking hiking style. Your choice lies between accommodating the occasional traveler to the gear-reduced hiker. Choose wisely.
