LBBJKT The Peloton Rolltop Bag vs. Patagonia Black Hole® Duffel 40L

In the world of carry on backpacks, there are high-flyers and then there are the over-achievers. The Peloton Rolltop Bag by Life Behind Bars Jakarta (LBBJKT), designed for the savvy traveller with a knack for cycling, is a versatile lifesaver. This backpack has an astounding capacity. It stands tall at 53 inches, spreads at 36 inches wide and 12 inches deep. This allows it to swallow up up to 35 litres of your travel essentials. The LBBJKT's feather-light nature is also compelling. At 1.6 pounds, it promises an effortless carry experience. With its bright yellow water-resistant polyester inner linings and robust YKK Aquaguard zippers, it makes a grand promise of keeping your wares safe and dry. And It's noteworthy laptop compartment accommodating a 17 inch laptop is cherry on top.

Then there is the Black Hole® Duffel 40L by Patagonia, a beast on its own terrace. It takes a more crafted approach, featuring a capacity of 40 liters. Although larger, the Patagonia is even lighter, weighing only 1.1 pounds. It doesn't lack in aesthetics either. With its 900-denier postconsumer recycled ripstop polyester, it's clearly made to last. Alas, the Patagonia left out a laptop compartment, which might be a deal-breaker for those travelling with a computer in tow.

• The LBBJKT is taller and narrower, while the Patagonia sports a more squat, rectangular shape. • The LBBJKT weighs more than the Patagonia, yet, eerily so, carries less. • The LBBJKT is friendly with almost all airlines, while the Patagonia falls behind slightly. • The LBBJKT's water-resistant features and zip system is a notch above the Patagonia's. • Both have great pockets for organization, but the LBBJKT trumps with a laptop compartment.

Both carry on backpacks are applauded by reviewers. One states, "If you're a cyclist looking for a suitable backpack, and if you don't mind the hook system to open and close, then the Peloton is perfect." Another stamps the Patagonia as a "great all-around option for world adventurers, weekend warriors, and casual travellers alike."

There are more reasons to consider these two backpacks though. The LBBJKT can expand from 35L to 45L when you need the extra space, offers a dedicated laptop compartment, packs a lot of convenient pockets, and comes with a strap system for attaching large items. On the other hand, the Patagonia maximizes its 40L capacity with its rectangular shape, screams sustainability with its recycled materials, boasts of convenient pockets for organization, and offers flexibility by being both backpack and shoulder bag. Both definitely have their shining points, and your choice would depend on your specific needs and preferences.
