MOUNTAINTOP 80L Internal Frame Backpack, Large Capacity Backpacking Pack

I just received this pack today, along with my girlfriends osprey ariel 75 AG for our month long trip to Australia in May. We will be able to do laundry so we will be bringing about enough clothes for a week. As we make our journey I will closely monitor both packs and be able to give a better performance review once we get back. For now, the suspension on the osprey looks like one you would expect on a $330 backpack. The one on my mountaintop looks like a solid $150 pack, but just doesn’t look like it will be as comfortable as the osprey, but it is also less than 1/3rd the price. Both packs seem to have close to the same features. I read a review about someone just recently not getting a pack with the mid pack access, but mine does have it. Not sure what kind of mix up happened there. As of now the pack looks to be well worth the money and I will update when we come back in June. UPDATE: We just got back from our trip and I have to say this pack did pretty well. I managed to get 7-8 days worth of clothes into it with the bottom hatch unzipped to use the entire pack, and did not have to get too creative in finding space. In total it weighed somewhere around 30 lbs when I had it fully loaded. As I was using this for a suitcase basically and not actually hiking, I have no idea how this would hold up in extreme environments but it made it through airport baggage so that’s a feat in itself. We only ended up walking max of about 30 minutes at a time with our packs, and it started to be a pain on my shoulders. Moving some weight towards the back and tightening up the belt very tight seemed to have helped but it wasn’t the most comfortable thing in the world. My girlfriend said her osprey felt much better so the osprey wins in the comfort column. Overall for the +/- $80 I paid for the mountaintop it has done well and I cannot complain too much. If we go on several hiking trips I may break down and spend $300+ on an osprey but for what it’s worth this pack has done very well and got the job done.

Did not have to use the rain cover and I kept it inside of our tent instead of the vestibule so it didn't get very dirty, but it fit everything I needed for the backpacking trip at a great price. It fits down to a 16in torso okay (my wife is petite at 5', 130 lbs) but you'll probably have to get an expensive Gregory backpack if your torso length is under 16 and you need 55+L. For me (5'8", 260lbs) the pack was perfect. It carried the weight of my stuff nicely except the brain of the bag... It can be awkward when stuff is put in there like a puffy jacket or something. I wish it was just a flap instead of a brain because it feels like wasted Ls. The front pouch doesn't stretch, so you can only put certain things in there if your pack is full. The side pockets are great and the hipbelt is awesome. Fit my 46in hips nicely. I would buy again and would buy this for my wife if her torso was 1 inch longer.

Just completed the Rim to Rim to Rim hike at the Grand Canyon which is approx 47-50 miles, with side missions, as well as dramatic elevation changes. I lucked out and had dry weather so I can't speak about the rain fly on the bottom of the bag but there is one and it seems to fit over a full bag. I used the 80L bag to carry my supplies over a 5 day 4 night hike and it held it all and with plenty of zippered pockets to add more if necessary. In the pics my sleeping mat was inside the bag but there are various locations to place a sleeping mat. I brought a sleeping mat that was way too big and heavy but the bag held it just fine. The shoulder straps felt decently comfortable but it could of had a bit more padding and with all the slide buckles I was able to adjust to find a comfortable fit. The bag is adjustable to fit your torso beautifully and the hip belt gives a nice snug fit so the weight sits on your hips nicely. There are pockets on the hip belt but they aren't easy to get into because the hip belt is usually going to be somewhat tight depending on your bag weight which for me was approx 35-40lbs. The side pockets can hold a 32oz Nalgene bottle but like the hip pockets they are too tight to reach back and pull the bottle out and put back. I had to have someone pull and put back the bottle for me. I used my 3L water blabber and it fit fine with the hose coming over the right shoulder and going through the chest strap to hold it. I liked this bag and was kinda impressed with the durability. No tears, zipperes zipped, and hike completed. In summary it is a solid bag that will do what you need it to do. Just plan right and pack it balanced and it will do the job.

I took this on a 7 day mountain backpack trip with a group of teen kids. Each day we tracked 4 to 5 miles up and down the mountain. It had Plenty of ways to adjust it but I found myself not having to make adjustments as much as the more expensive ones that others had. It worked great

Lots of storage space in your survival backpacks, lots of zipper pockets plus plenty of room for your needs

Excellent pack for the money. Most lightweight backpacking setups cost 100s more and offer less features. This pack has a built in rain jacket, great support for attachments, and plenty of compartment space while being reasonably light. You can find lighter packs for sure but they are WAY more expensive. This one is still comparable weight wise with many of the far more expensive brands. I recommend it!

I have had the 65L version of this pack for about 5 years now. I wanted to upgrade to the 80L and I am so glad I did. This pack had more room and more compartments to put stuff in. We just came back from a 4 day trip in the ozarks with up to 50lbs at the heaviest for the last 10 miles of a 30 mile hike. None of the stitching failed and I put this pack through some hell. From throwing it on the ground to make myself a quick seat, to lifting it up fast and throwing back over my shoulders to get ready for the next stretch. This pack held together through all the bumps against rocks and trees. Also had to do a lot of jumping from rock to rock and it held tight to my back with very minimal sliding, I mean hardly noticeable. For a budget backpack I’d say it would hold up against even the higher ends. Very well worth the 110 dollrs as of May 6, 2025

Great bag, lots of room to over pack haha. Padding was comfortable, loved that you could adjust the size.

Resistente y muy cómoda para tu espalda

Excelente todo bien
