Has this bag for 5 years and it has gone all over the world with me. The 45L is the perfect carry on for all my flights and travel. Sturdy, waterproof, and a lot of space for packing. I tell all my friends to buy it!!

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.

I was looking for a duffel backpack that can be used for gym and work. There are many bags out there that have laptop compartment but they’re never comfortable when in use in real life scenario. You’re better off just getting a sturdy laptop case (I recommend Tomtoc or Thule) and using it without a laptop compartment within a strong bag (just my recommendation). That’s where this bag by MIER comes in. The end pocket is perfect for shower sandals and soiled clothes. The main compartment is big and perfect to put in first the laptop, followed by shower toiletry bag, and change of clothes. The zip internal pocket and the external side pocket are big enough to hold your phone, wallet, keys, and everything else. I’ve tried Under Armour, North Face, but this bag does it for me. One thing you’ll have to get used to is the width of the backpack strap. They’re comfortable but really wide. Just something for you to know.

Used this on a trip to Bali. It worked well. Well made and seems durable. Good size. The shoulder straps are not very comfortable at all but it was nice to have them. A hip belt would be extra nice but not necessary.

I will say that as I was using it, I noticed that the straps do not curve inward away from the shoulders and this created a lot of discomfort for me. The straps do curve, but at the wrong end, maybe. Great brand, great bag, but I am small in stature and the straps are made to be very durable, however they are also made for a larger person. This bag can take a lot of weight with no problem. I filled it to the brim with clothes but I have no doubt it can take heavier objects, anything you need in the field will be fine. The walls are sturdy and not easy to tear, the storage is ample, true 90 liters, the pockets are easy to get into, and the positioning prevents things from getting loose and falling out. Zippers are sturdy and plastic and metal, the zipper line is plastic, the zipper catch is metal with smooth zipping. Very secure bag. I recommend this for camping and other ventures, def good for hunting. Waterproof as I tried it out in full rain, everything kept perfecly dry. This is built to last, no flimsy seams, no sloppy sewing in the seams. I will defnitely be buying this brand again. Actually, I already did, just got the smaller version of this bag, as the 90 liters was a mistake for my weight capacity. This is a very no nonsense unit very thoughtfully put together.

im a travel blogger who’s against checking in luggage. I love this bag (45L). Tens across the board. I own the osprey stratos. It’s a 50L hiking backpack I’ve been using for 6 years. The osprey stratos is the perfect overhead bin traveling backpack. It developed a smell after hiking in Asia and I didn’t have time or energy to clean it and I also wanted a backpack that was more casual. Having this bag ship the next day was the easiest solution. My criteria for a new bag was that it was at least 40L, Could double as a duffle bag and a backpack, had side straps for compression . And was decent quality (good zippers and thick skin). This bag checks all the boxes And more. This bag has plenty of room for a weeklong trip or more depending on how and what you pack. Because I tightened the straps there was even more room than what I had packed. It easily stows in the overhead bin with room to spare. It’s also water resistant. That’s a plus. It’s lightweight on its own. Kinda stylish as well. I’m happy and thankful for this purchase. For this price point ($50) I don’t think there’s much out there that beats this. But if I could perfect it, I’d like for the backpack straps to be more padded. They’re a little thin. I would like at least one more pocket on the top lid for convenience. But that’s just me being extra. This bag is fantastic. I’m about to buy 4 more for my family.
