7 Best Carry On Bags for Allegiant 2025

This versatile weekender bag redefines organization for travelers who refuse to compromise on style or functionality. With a dedicated shoe compartment, zippered wet pocket, and multiple external access points, it tackles two of the biggest pain points in carry-on travel—messy spills and disorganized essentials. Crafted for gym-goers and frequent flyers alike, its personal item dimensions (17.7×12.6×6.3 in) ensure it slips neatly under Allegiant seats, while the trolley sleeve lets you stack it over luggage for seamless airport navigation. It’s a rare blend of thoughtful design and everyday practicality.

In real-world use, the ETRONIK bag shines during weekend trips and gym commutes. The spacious 25L interior fits a change of clothes, shoes, toiletries, and even a towel—thanks to the fully lined wet compartment that prevents damp gym gear from soaking your dry items. Side water bottle pockets add convenience, and the secure back zip pocket is ideal for passports or cards. However, the lack of a USB port or smart features may disappoint tech-focused users, and the shoulder strap, while padded, doesn’t offer the breathability seen in backpack-style options.

Compared to the LOVEVOOK or ECOHUB models, this duffel trades tech integrations for superior wet-dry separation and shoe storage—making it ideal for athletes and minimalist packers. It’s not the most feature-packed, but for those who value clean organization over charging ports, it’s a standout. While the ECOHUB offers more pockets and USB access, the ETRONIK wins with its dedicated shoe and wet zones—a combo unmatched at this price point.

Don’t let the ultra-affordable price fool you—this foldable duffel is a budget-savvy traveler’s secret weapon against carry-on fees. Sized precisely at 17.7×12.6×6.3 inches, it’s tailor-made to slide under Allegiant, Spirit, and Frontier seats, helping you avoid $40+ baggage charges per flight. The thick-lined interior and full-zip mesh pockets offer surprising organization for such a compact bag, making it a no-brainer for spontaneous trips or as a secondary under-seat pack.

During testing, the bag proved remarkably lightweight and packable—folding down to the size of a large wallet when not in use, perfect for throw-in luggage. The two internal mesh pockets keep smalls like chargers or snacks sorted, and the padded shoulder strap delivers comfort for short hauls. However, it lacks advanced features like a trolley sleeve or wet compartment, and the single main cavity can become chaotic on longer trips. It’s best suited for light packers or weekenders, not those hauling tech or gym gear.

Against pricier rivals like the ECOHUB or LOVEVOOK, this duffel stands out purely on value and portability. It doesn’t compete on features, but for travelers who need a reliable, no-frills personal item, it delivers. While the Taygeer backpack offers makeup storage and USB charging, this bag wins on pure affordability and foldability—a true stealth asset for fee-conscious flyers.

Meet the eco-conscious traveler’s dream: a 30L under-seat backpack that blends sustainability with smart tech. Its 18x13x7.8-inch footprint fits Allegiant’s personal item limits with room to spare, while the USB charging port and expandable water bottle pocket cater to digital nomads and hikers alike. Built from 50% recycled materials, this backpack doesn’t just reduce plastic waste—it’s engineered for endurance with water-resistant fabric and ripstop stitching, making it a planet-friendly powerhouse for frequent flyers.

On the move, the ECOHUB impresses with its suitcase-style opening, allowing full visibility of the interior during packing or TSA checks. The 13 thoughtfully placed pockets include a hidden back slot for wallets, a top-access panel for documents, and a quick-zip toiletry pocket—ideal for stress-free security lanes. Side compression straps let you cinch the bag when half-full, and the luggage pass-through keeps it paired with rollers. Still, the lack of a dedicated shoe or wet compartment may frustrate gym users.

Positioned between the LOVEVOOK and Taygeer, the ECOHUB leans into eco-credentials and charging convenience over storage specialization. It’s lighter than the LOVEVOOK and more sustainable than most, but lacks the packing cubes or shoe bag extras. For travelers who prioritize tech access and environmental impact, it’s unmatched. While the LOVEVOOK includes more organization tools, the ECOHUB pulls ahead with its charging port and recycled build—a smart pick for green-minded jetsetters.

This duffel is a comfort-first game-changer, turning your under-seat bag into a mobile relaxation kit. With a built-in USB port and a free foldable air pillow, it’s engineered for travelers who see flights as downtime—not just transit. The 16x14x7-inch size is a perfect match for Allegiant’s strict personal item rules, and the water-resistant fabric adds peace of mind during rainy commutes or spills. It’s one of the few bags that combines utility with in-flight comfort, making it ideal for red-eyes or long layovers.

In daily use, the USB port works seamlessly with a power bank (sold separately), letting you charge your phone without unpacking. The foldable design means it stows easily in a closet or suitcase when not in use—great for occasional travelers. However, the interior lacks dividers or wet compartments, so organization relies entirely on how neatly you pack. The shoulder strap is comfortable but not padded, and there’s no trolley sleeve for pairing with larger luggage.

When stacked against the ETRONIK or Taygeer, this bag trades advanced storage for comfort perks. It doesn’t offer makeup organizers or shoe compartments, but the included pillow and charging access are unique at this price. While the ETRONIK delivers better organization, this duffel wins for in-flight comfort and simplicity—a rare blend of convenience and coziness for Allegiant flyers.

If you’re after the gold standard in personal item duffels, this 40L powerhouse earns its title as the Best Overall. Sized at 20.5x14x8.7 inches, it fits most major airlines’ carry-on limits—including Southwest and Alaska—while still slipping under Allegiant seats when needed. Built from 900D waterproof nylon, it’s tear-resistant, durable, and weather-ready, with reinforced stitching and smooth SBS zippers that survive repeated use. This is a bag designed to last years, not just weekends.

Real-world testing confirms its versatility: the wet/dry separated side pocket safely holds damp towels or toiletries, while the side shoe compartment keeps soles away from clean clothes. The trolley sleeve frees your hands at the airport, and three mesh interior pockets plus dual side bottle holders ensure everything has a place. At 40L, it’s spacious enough for 4–5 days of travel, outpacing smaller 25L rivals. The only caveat? Its size may push the limits on tighter planes.

Compared to the ETRONIK or Allegiant-specific duffels, this bag offers broader airline compatibility and superior build quality. While pricier than budget picks, it matches the LOVEVOOK in capacity and exceeds it in durability and wet-storage design. For travelers who want one bag that does it all—gym, travel, weekend trips—it’s unmatched. While the Taygeer has more tech pockets, this duffel dominates in ruggedness and storage flexibility.

This 40L powerhouse isn’t just a backpack—it’s a complete travel system. With three included packing cubes and a shoe bag, it delivers unmatched value for organized travelers. The 180-degree suitcase-style opening makes packing and TSA checks a breeze, while the foam-padded laptop sleeve keeps your 17-inch device secure. Sized at 18x14x8 inches, it fits Allegiant’s personal item limits and most major airlines, making it a true one-bag solution for 3–5 day trips.

On the road, the ergonomic padded straps and breathable mesh back reduce shoulder strain, even when fully loaded. The anti-theft back pocket and luggage pass-through add security and convenience, and the built-in USB port (cable included) keeps devices charged. The dedicated wet pocket handles sweaty gym clothes with ease. However, the bag is slightly heavier at 2.2 lbs, and the packing cubes, while helpful, eat into usable space if overused.

Against the ECOHUB and Taygeer, the LOVEVOOK stands out with its all-in-one value pack. While the ECOHUB is lighter and greener, and the Taygeer offers a makeup compartment, this backpack includes everything you’d buy separately. For travelers who hate juggling accessories, it’s a dream. While the ECOHUB wins on eco-credentials, the LOVEVOOK delivers more bang for the buck with its included cubes and shoe bag.

This organization-obsessed backpack is tailor-made for travelers who live by the mantra: everything has its place. With 8 compartments, including a front makeup compartment with brush holders, detachable shoe pouch, and AirTag pocket, it’s the most meticulously designed personal item bag in the lineup. The 18x14x8-inch profile fits Allegiant, Spirit, and Frontier, and the 180-degree lay-flat opening speeds up packing and TSA checks—ideal for business travelers and beauty enthusiasts alike.

In practice, the makeup compartment is a standout, keeping brushes and palettes upright and visible—no more digging through zippers. The wet bag contains damp items effectively, and the hidden anti-theft back pocket adds peace of mind in crowded terminals. The USB charging port and luggage pass-through round out the convenience. However, the shoe compartment is detachable but not ventilated, so odors can build up if used for sweaty footwear.

Pitted against the LOVEVOOK and ECOHUB, the Taygeer wins on specialized storage—especially for makeup lovers. While the LOVEVOOK includes packing cubes, the Taygeer offers built-in, permanent organization. It lacks the LOVEVOOK’s included accessories but excels in daily usability and aesthetic appeal. For travelers who prioritize beauty kit access and compartmentalization, it’s the clear leader—out-organizing every other bag in the test group.
