It's a good duffel bag, but a mediocre backpack

Sean T LeonardNovember 17, 2025✓ Verified purchase

I bought the 90L duffel a year ago and so far it has survived four international flights and several road trips with no issues. If you use it as intended, it's a good bag for the price. First of all, it is a duffel bag that happens to have backpack straps, it is not a backpack with duffel handles. What that means is that, while you *can* carry it on your back, doing so with a large load for a long duration is going to be extremely uncomfortable. Also, the straps are a compromise item because they need to be stowable when not in use, so they're held in place with plastic buckles which can fail when abused. Also, if you don't secure and stow the straps before checking the bag at the airport, there's a good chance that the baggage handling machinery is going to rip the straps off. As for organization, this bag is geared towards transportation and storage. It's a single large compartment and a few smaller pockets, it's not really meant for living out of while you're traveling unless you're also using bag organizers. Keeping all that in mind, it's a big, sturdy, water repellent duffel that doesn't take up much space when it isn't in use. My only real complaint is that the zippers don't have lock rings, so I have to run my TSA lock through the pull tabs. Read more

Great bag and excellent Value

Jan AlbertiNovember 23, 2024✓ Verified purchase

★★★★☆ A Tough Tank of a Travel Bag! This MIER duffel is a beast - built like a tank with heavy-duty tarpaulin that laughs at rough handling and rain. The massive D-shaped opening and mesh organizer pockets make packing a breeze, while the backpack conversion option adds fantastic versatility. I've stuffed a week's worth of gear in here with room to spare. Only knocked one star off because while the straps are decent, they could use more padding for heavy loads, and I really wish it had a waist strap for better support. Still, for the price, you're getting an incredibly durable, versatile bag that's ready for any adventure you throw at it. Read more
