Mountaintop Internal Frame Backpack

Internal Frame Backpack with Gear

A backpack is easily your most important piece of gear when you’re out or a multi-day trek into the wilderness, mainly due to the fact that it’s what allows you to carry all of your essential gear in the first place.

Capacity and comfort are two of the bigger factors that help determine whether or not a backpack is quality and dependable product. Ease of access and additional storage methods follow closely behind. Your backpack’s capacity directly determines the amount of gear you can have, and the comfort factor obviously influences how backpack full of gear feels for 8-10 hours a day.

Overlooking these things can result in a rather miserable outdoor experience, so it’s always best to seek out a backpack that you are fully confident in. This can often leads to spending hundreds of dollars in the process.

Fortunately, Mountaintop has managed to create a large capacity backpack that is both spacious and very comfortable, all for a fraction of the price.

Features & Benefits

There is a lot to like with this backpack, and it's obvious that Mountaintop put a lot of thought and planning into it.

Lots of Adjustability

Size and fit are huge aspects of ensuring that a backpack is comfortable on a long journey, while also distributing weight on your hips and legs more appropriately. The problem is that everyone is shaped different, so this can be a little complicated.

Mountaintop Internal Frame Backpack Adjustability

This backpack features numerous ways to adjust the fit and even size of the pack. The torso length can be adjusted in 8 different sizes, giving you a lot of flexibility in that area when compared to other backpacks. The advantage cannot be stressed enough, as it helps provide a precise fit.

Numerous Storage Options

Not only does this backpack come with a large amount of pockets and compartments, it also includes 10 compression straps that can help you attach anything from a sleeping pad to tent poles in a simple and easy way.

The straps retract when not in use, so you don’t have to worry about them dangling all over the place.

Unique Advantages

Expandable Capacity

This pack can already fit 70 liters worth of gear inside, but if you need a little extra room, a quick pull of the drawstring on the upper extension collar will give you an additional 10 liters. This can come in very handy on longer trips.

Separate Bottom Compartment

One of the most annoying hassles with backpacking is having to fit everything into one giant compartment, whether it’s your sleeping bag, change of shoes, or whwtevr else. Mountaintop combatted this by including a wholly separated bottom compartment that you can easily access in just a few seconds.

Potential Disadvantages

Small zippers

The zipper size leaves a little to be desired, making them harder to zip and unzip when the backpack is at capacity. Mountaintop would be wise to increase the size on their next version of this.

Rainfly Size

While it’s nice to have an included rainfly that can be pulled out and cover your bag to keep it dry, it’s a pretty tight fit. In fact, if your backpack is at capacity, you may not be able to fully enclose the bag.


It’s pretty incredible that you can get a backpack of this size and quality for under $100. The adjustability, smart storage options, and extra capacity features are just a few of the reasons why this Mountaintop backpack is built for even the most demanding journeys.
