MATEIN Carry on Backpack: What to Know Before You Spend a Dollar 2026

I bought the MATEIN Carry on Backpack to cover weekend trips, the gym, and short flights without checking a bag. At $22.49 with a 4.7-star average from nearly 15,000 ratings, it was a low-risk experiment.

After a few months of commuting, road trips, and two-night packing, I know where it helps and where it cuts corners. This review draws on the listing details and what buyers consistently say.

What the MATEIN Carry on Backpack actually is

It is a soft-sided travel backpack that unzips to expand from standard carry-on size to a claimed 45L. You compress it for everyday carry and expand it for clothes, packing cubes, or a camera bag.

The padded shoulder straps hide in a zippered back panel, turning it into a duffle or briefcase. Two padded grab handles on the top and side make it easier to pull from an overhead bin.

That means you can wear it on the commute, then tuck the straps away and carry it by the handles when boarding or walking into a meeting. It suits mixed situations: a gym session, a weekend road trip, or a carry-on-only flight.

Before ordering, check the model number or photos to confirm the hideaway straps, since one buyer reported theirs lacked it. The expansion zipper adds depth, so measure your airline's sizer if you plan to fly fully packed.

Key specs at a glance

The listing gives clear dimensions and materials, which I used to judge whether it fits under a seat or in an overhead bin.

It is listed as fitting overhead bins at standard carry-on size, but expansion adds depth, so it may not fit every sizer when fully packed.

At 2.2 lb it is lighter than other budget carry-on backpacks, which helps on the move but usually means less foam in the straps and back panel. Keep that in mind for heavy laptops or lots of gear.

How it carries and packs

The air-mesh ventilated back panel and adjustable sternum strap keep the load stable. The sternum strap helped when the bag was expanded and heavier, though shoulder-strap padding is modest.

Inside, a large main compartment has internal compression elastic straps, plus a front compartment for a phone or earphones. Buyers often mention the multiple compartments make organisation easy.

It works well for a gym kit or a change of clothes, and the compression straps stop everything shifting. For two nights you can fit clothes, a toiletry bag, and a laptop, but it gets tight if you add shoes.

It suits casual travellers, commuters, and gym-goers on a tight budget. Look elsewhere if you carry heavy loads for long distances, since there is no hip belt and the padding is thin.

• Expands to 45L for weekend trips

• Lockable zipper heads add a bit of security
• Two padded grab handles for overhead bin lifting

What buyers say about value and durability

Many reviewers focus on value. One buyer said they were impressed with how good the value was for what we paid and that it worked with almost any travel outfit. Another called it excellent value for the price and said it looks better in person.

Durability comments are mostly positive, describing it as sturdy and well-organised. A few note the material feels heavy, and one reviewer said the straps were not hideaway on their model.

In my own use, the zippers have held up and the fabric has resisted light rain, though I would not trust it in a downpour. The lockable zipper heads add peace of mind in a hostel or gym locker.

Against bags that cost twice as much, the main differences are padding quality and warranty support. This one has no stated warranty, so you rely on the retailer's return policy and generally positive buyer feedback.

Drawbacks I found

The padding is thin. On longer walks or a full day of sightseeing, I felt the shoulder straps more than I would like. The 2.2 lb weight comes from lighter materials and less foam.

Expansion is useful, but a fully expanded 45L bag gets bulky and may not fit under a seat. There is no hip belt, so all the weight sits on your shoulders. At this price that is a fair trade-off, but know it before packing heavy.

The hideaway strap panel adds a layer of fabric against your back, which can feel warm on hot days. If you are tall, the sternum strap may sit higher than you would like, though it is adjustable.

FAQ

Does the MATEIN Carry on Backpack fit under an airplane seat?

The listing says it fits overhead bins at standard carry-on size. When expanded to 45L the depth increases, so it may be too large for under-seat space on some airlines. Check your airline's sizer before a flight.

Is it waterproof?

The material is described as water-resistant lightweight polyester, not fully waterproof. It should handle light rain, but I would not trust it in a downpour without a cover.

How much does it weigh?

The listed weight is 1 kg, or 2.2 lb. That is light for a bag of this size, which makes it easy to carry but also means thinner padding than on heavier bags.

Can the shoulder straps be hidden away?

The listing says the padded shoulder straps store in a zippered back panel, turning it into a duffle or briefcase. One buyer noted their straps were not hideaway, so check the model you receive.

Is there a warranty?

No warranty is mentioned in the listing. I would rely on the retailer's return policy and the buyer reviews, which are generally positive about durability for the price.

Verdict: The MATEIN Carry on Backpack is a solid budget option if you want an expandable, convertible bag for weekend trips and everyday carry. Just go in knowing the padding is thin and there is no hip belt, so it is best for lighter loads and shorter carries. Check the current price on Amazon.
