What We Liked About The Mountaintop 55L/65L Backpack

Adjustable Torso Length

Mountaintop 55L/65L Backpack is an adjustable backpack that can suit every type of hiker. It has a torso length adjustment with 8 levels which can be set for different torso sizes.
No worries about the bag’s dimensions when you buy it because you can adjust its back length to fit you. This makes it an ideal item for a family who likes hiking since many members of the family can use it.

Available In Two Sizes – 55L and 65L

It is available in two-volume capacities – 55L and 65L. The 65L backpack would be large enough to bring everything you need for a one-week hiking trip. If you are not such an avid hiker, then the 55L backpack would be fine.
The main compartment is divided into two. This is useful for when you bring contents that need to be separated. Also, there is an extension collar that can expand adding 5L more to the main compartment’s capacity.

Durable YKK Zippers and Buckles

Of course, having a large capacity calls for durable materials. The backpack uses high-quality YKK zippers and buckles. They are durable enough for long-time use. Also, the zippers glide open and shut with ease.

Water Resistant Nylon

It is also made with water-resistant nylon which is easy to clean. Take a damp cloth to spot clean the backpack. After hiking on a rainy day or on wet terrain, just air dry the bag.

Inbuilt Hydration System

The overall capacity of its hydration system can carry up to 3L. This is a lot of liquids that can last a long hiking trip. There are also loops to hold hiking poles and ice picks.

Emergency Whistle

For emergencies, the buckle of the sternum strap doubles as an SOS whistle. It is useful since whistles or other small objects are easy to lose when hiking. Also, it is easier to access the whistle from the sternum strap.

Attachment Points

Key hooks inside the main compartment keeps important things secure. You can also use the D-shapes hooks on each of the straps for other objects you need to access quickly.

Separate Wet Storage Area

Under the backpack is another separate compartment. It’s designed as a shoe compartment, but it can also be used for wet items like clothes or towels. The water doesn’t seep through the main compartment.

What We Didn’t Like

Despite all its great features, Mountaintop 55L/65L has its disadvantages.
One main concern here is the poor transfer of the weight on the hips. This problem often occurs when it is at its maximum capacity. After hiking for hours, it can become uncomfortable in this situation.
We have also noticed how some Velcro straps can be sticking out. When using the backpack, the Velcro straps can sometimes stick in the back.
It can also be prone to tears if it is over packed. Filling the bag only up to 30 pounds may be best.
Another thing is that the adjusting feature can be troublesome. It is tedious and may take some time. This backpack may not be suitable for taller people despite the adjusting feature.
As for the little things, it is not water-proof. It may be water-resistant, but it is still not enough to assure you that your belongings will not get wet. This is why the backpack comes with a high visibility rain cover.
The backpack doesn’t have a sleeping bag compartment. It does have compression straps where you can attach a sleeping bag. But, it may not be as secured as backpacks with a sleeping bag compartment.
Popping the backpack in the washer is not an option when cleaning it. This may be a difficult cleaning task for some people.
They could have added more side pockets for easier access.


Mountaintop 55L/65L Backpack may have some issues. But it still is a reliable and versatile hiking backpack. We would recommend this for young, beginner hikers.
It is a versatile and generally comfortable backpack because of its adjustable back. The aesthetic design can be appealing for hikers of different ages. It is sleek, elegant, and there are many colors to choose from.
The backpack may have a 65L capacity. But, it is recommended not to load the backpack up to its limit. We suggest that you only load it up to 30 pounds.
Comparing it with $200 backpacks, the Mountaintop 55L/65L may not stand a chance. But compared to other hiking backpacks in its price range, the Mountaintop 55L/65L is a good option.
After a lightweight, cheap and versatile backpack, then look closer at this backpack. It’s affordable compared to other hiking backpacks. You also get great features for its well worth price.
