Review: Sturdy, high quality fabric and material, and exceptional customer service. - I debated purchasing the MIER Large Duffel Backpack for quite sometime. It was difficult to see if it was well-made and sturdy. When I received it, I'm glad I purchased it based on these two points. The first duffel backpack I purchased was coming apart at the seams. Customer service contacted me through this review, immediately, and offered to send a replacement. The company representative was very attentive and responsive to my questions and messages. A replacement was sent out swiftly. The turnaround time to send out the replacement was two days and the shipping speed was priority. 1. Company backs up their warranty and replacement program. 2. Exceptional customer service. 3. High quality fabric + material, and very sturdy. 4. It does not feel like a flimsy duffel backpack or bag that you purchase from a sporting goods store. 5. Able to fit a basketball, shoes, clothes, large water bottle, and accessories such as a foam roller in the 45L version. I recommend a larger size if you want more space. 6. Great duffel bag or backpack conversion design. Use the strap as a duffel bag, or use the twin straps like a backpack (three straps total). All straps are removable and easy to store away inside the bag. 7. Understated, subtle look. 8. No big brand name logo plastered all over the bag. 9. Minimalistic look. 10. Excellent value. I'm very picky about sports gym bags. This one ticks all the boxes. It is heavy duty, durable, and has a high quality feel. It is water resistant has the company claims. The minimalistic look without brand name logos being placed all over the bag is a huge plus. Mierlife does stand by their product. They do care. A customer service team member reached out to me first before I even thought about doing so. And they were able to send out a replacement, quickly. Very kind and professional.
Review: Great quality for great price - This is such a great bag for weekend trips or camping trips. I also use it for a gym bag, so it’s nice that they have the inner pocket in the side pocket. I love that the bag comes with both the backpack straps and the regular duffel sling because I can bike to the gym with it on my back, but don’t want it to be a backpack all of the time. The material is great and durable - similar to those expensive north face ones. Plus, the colors are great. Main qualms are this: when backpack straps are on, it is difficult to zip and unzip. I don’t know how you would really circumvent this issue, but i find that the overhang over the zipper contributes to this issue. That overhang is nice for extra protection however. I also wish there were a few more smaller pockets. There’s a really small thin side pocket that runs parallel to the bags length and then one side of the barrel that opens up. I wish both sides opened.

## Questions & Answers

**Q: Can the 60 litre size bag be used for carry-on on an airplane?**
A: That's an iffy situation I had the 90 liter one and I use it as carry on. But I'm a big guy and my girlfriend who's 5"2 had the exact same bag and they wouldn't allow her to use it as carry on.  I think technically it's too big but nobody really pays attention to backpacks unless it's obviously oversized when they look at you

**Q: Hello, i ordered this backpack back in march. and the clips that hold the duffel bag broke on me when carrying the bag. is there any way you can help.**
A: contact the manufacturer - I have done this for another product that I'd taken out of the package and used but it was defective, the manufacturer (contact info on the tags on the bag in this case) would be happy to replace

**Q: Is the 60L still available?**
A: Thanks for contacting MIER. The bigger sizes (60/90L) will be arrival at Amazon warehouse in early January 2020.

**Q: where on the product can I see mark indicating the volume of the bag I was sent?**
A: The volume print is printed on the top flap of the bag.

### ⭐⭐⭐⭐⭐ Great bag..Smaller actual dimensions but still equals far more than 45L
*by A***X on July 19, 2026*

I purchased this 45L after questioning the actual measurements of the 60L and although I was right, it wasn't a bad thing. (I'll post a review on 60L later) So the number don't quite add up based on actual volume vs what's advertised, but that's in a good way. I filled the bag completely to test its true capacity since you can never be too sure. The listing states the 45L to be 23.25" X 13" X 13" and although it's significantly smaller in the maximum height, it's large in the length. Measuring strictly from the outside, it measured 25.25" x 13" x 11" and if you do the math, that equals to about 59L external and probably 58L internally. So clearly that's great, however keep in mind that if you are someone that is seeking to buy a 45L because you're concerned about the overall weight, this may be more of an issue for you. The quality is unquestionably great and if taken care of, it could probably last years. My only gripe about the 45L version is the shoulder straps, they feel like cardboard with almost zero padding and definitely lesser quality than the 60L version. I want to assume they cut corners thinking it needed less support than the 60L, but that would still be wrong considering that when full, this easily weighs 50lbs. It's a good price for the value you're getting.
