When looking at carry on backpacks, we're focusing today on two distinctly different bags. The Cotopaxi Allpa 35L by Cotopaxi and the ILE Radius XL by Inside Line Equipment (ILE). The Allpa 35L is a robust contender in the bag space with its ballistic nylon paneling and an impressive 35 liters of capacity. Its compatibility with 80% of airlines gives the conscious traveler peace of mind knowing they can carry it onboard without issues. On the other hand, the ILE Radius XL, woven from Durable Cordura Nylon, XPAC Sailcloth, or Waxed Canvas, gives off an air of versatility and endurance. Offering a slightly bigger capacity at 40 liters, this hefty bag boasts compatibility with 65% of airlines.

Diving into some specifics, lets compare and contrast:

Coming to customer reviews, the Cotopaxi seems to win hearts both for its simplicity and intuitive internal organization. Quartets like "perfect graduation gift for the budding world traveler" and "best configuration I’ve used so far," reverberate throughout various review excerpts, affirming Allpa's popularity.

Finally, touching on unique selling points, the Allpa 35L is a travel friendly model, its bundle includes a rain cover, a collapsible mesh laundry bag, nylon shoe bag, and a mesh water bottle sleeve adding convenience and security. Additionally, it's been praised for its comfortable shoulder straps, a hip belt and adjustable sternum straps. Comparatively, ILE Radius XL is handmade and comes in multiple fabric variations, alluring those who fancy custom-made products. Its weather-resistant main compartment ensures your belongings remain safe in erratic weather conditions.

In conclusion, both bags have their strengths and it truly comes down to your specific needs as a traveler. The Cotopaxi Allpa 35L is a reliable option for those who appreciate thoughtful design, comfort and airline compatibility. The ILE Radius XL, however, is more of the outdoorsy type, its handmade craftsmanship and weather resistance makes it a perpetual ally in your ventures.
