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.

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.

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.

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.

Best purchase I’ve made in a while. Used this for the gym. I only used as a bookbag but I kept a basketball (size 7) and my sneakers (size 13) with no issue on space. A great weight but can get heavy if not packed correctly. With it doubling as a duffle bag, packing will take trial and error because when it goes from horizontal to vertical things change & now you have something constantly poking you in your back. It’s has pockets galore, to the point I’m still discovering pockets & slots I never noticed. I put the bag through the wringer, it survived snow , rain , a dog attack and no scuffs or scratches to boot. But the bag I recommend the biggest size or the one right below it and you’ll have all of your prayers answered.

I LOVE THIS 90L BACKPACK/GYM BAG. IT IS REALLY SPACIOUS !!! I AM NOT PLANNING TO HIDE IN THE WOODS FOR A FEW WEEKS, BUT ON MY WAY TO THE GYM, I STOP OFF AT THE LIBRAY AND DO SOME SHOPPING WITH PUBLIC TRANSPORTATION. THIS IS THE ONLY BAG THAT GIVES ME THE SPACE I NEED TO CARRY EVERYTHING I NEED: TWO TOWELS, RUNNING SHOES, SHOULDER BAG WITH SNACKS, WATER BOTTLE, WEIGHT ROOM ACCESSORIES, GROOMING & SHOWER THINGS, LUNCH AFTER WORKOUT, ETC., ETC., ETC. THE 90 L IS NOT MUCH HEAVIER THAN ALL THE REGULAR BACKPACK GYM BAGS I TRIED. IT IS REAL QUALITY!

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.

So far so good. Was asked to review these 2 bags I bought. ( 1 45L and 1 60L). Bare with me as I have to retrain my spell checker and can't shut it off, cuz Google says so. I have barely had had these for a few days, so my opinion and review will change after a few weeks. Overall first impressions. 1. Smaller than imagined, but that's on me. No matter what I do, I always translate liters to gallons in my head instead of quarts. 2. The bag itself seems sturdily built. Reinforced seams, and mount points for straps amd such. Tough plastic bottom that is still flexible. The "fabric" for both the upper and lower portions seems like it could shed water for days. Don't yet know about the seams or zippers tho. 3. As others have mentioned before me. I wished that there was a way to either remove or tuck away the shoulder straps for "backpack mode". ( They do unclasp from the "bottom" of the bag, but this adds another issue ill go over next.) This is costing a star no matter what, as they can get in the way of using the zipper ON THE MAIN COMPARTMENT. Since the main compartment is this bags reason for being and it's primary function, then why were the Non Rrmovable straps placed there of all places??!?! 4. Shoulder strap seems made well enough, double stitched and of a high quality fabric. With a movable shoulder pad like you'd expect. However, ( as alluded to above) the flaw i immediately see is the all plastic triangle connectors on the bag and straps. There's a metal spring hasp on the hooks, But my thought there is "what a waste of money" as the only metal on the entire design is Decorative, not load bearing in any way. So In summary. Just from experience and 10 minutes of close inspection. If you are planing to use these for travel or light camping in average weather once or twice a year, then these should work well for you, and will likely make great weather resistant upgrade. But if you need a durable bag that will last for more than a year of travel and will have to be mission critical in reliability. I.E. Coast Guard, lineman, park ranger, minimalist camper. Than buy the real deal cuz this isn't gonna be a good shortcut for your wallet. The plastic tackle and zippers will most likely fail you when you most need them.
