The Durable & Waterproof Tough Backpack from "Mountain Hardwear" – What Makes the "Scrambler" so Popular?

In winter, you have winter backpacks. Summer backpacks may have some inconveniences, such as snow getting into the mesh, but winter-specific backpacks do not have such worries. Rather, backpacks that can be used in winter are built to withstand year-round usage specs.
 
The popular product from Mountain Hardwear called Scrambler is based on a climbing backpack. It is also suitable for carrying winter gear like axes (ice tools) while being simple enough for year-round use. Its suitability for urban use likely contributes to its widespread popularity. I visited Columbia Sportswear Japan and spoke with Iori Kondo from the Mountain Hardwear product department.

A Versatile Backpack Excelling in Climbing, Trekking, & Urban Use

 "It has a neat appearance, is lightweight and durable, so it's easy to handle for those using a mountain backpack for the first time. The components can be easily removed or customized with options, allowing users to enjoy various mountain activities while keeping it for a long time. I personally selected the 'Scrambler' 35L model (scheduled to return in 2025) for its stylish look, wondering if I could handle it, but it is a very versatile backpack that can be adapted according to level and circumstances.
 
"That’s why it sells very well. It can be said to be the most popular backpack from 'Mountain Hardwear,' representing the brand. The difference between the 25L and 35L models lies not only in capacity but also in the specification of the hip belt. The larger 35L model has a hip belt that provides more support to the hips and can be comfortably carried even on long hikes. Both can be detached, so if you don't need it, you can remove it for simpler use."
 
According to Kondo, what makes the "Scrambler" appealing is its seeming simplicity, while also being easily customizable to the user’s needs. When I asked for details on how it could be detached, it certainly seemed like this one backpack could adapt to various situations.

The 25L capacity and weight of 848g may seem lightweight at first glance, but the aluminum frame and foam on the back of the pack provide stability when worn, making it feel even lighter. Both the aluminum frame and foam are removable, accommodating an ultralight preference. Removing the top rain cover can further reduce weight. Attaching the rain cover enhances waterproof capability, which is a nice option to have. This means fewer backpacks need to be owned.
 
"The compression straps on both sides (the horizontal straps at the top) are also detachable. The one-pull strap that secures the rain cover at the front (the vertical strap) can also be removed, allowing complete detachment for those wanting to minimize weight or use it simply.
 
"The one-pull strap can be easily stretched or shortened, so lengthening it allows for the attachment of climbing gear, such as ropes. This feature seems tailored for those using climbing ropes. Additionally, other than the one-pull strap, both sides' compression straps can be used to secure extra gear."

Compression straps are used to tighten the outer part of a backpack to prevent the internal contents from shifting when there is extra space. Many people also use them to attach items like a sleeping pad for tent camping. They are especially useful for smaller items like a Sierra cup or a bear bell, rather than larger ones.

"To secure trekking poles, pass the tips through the loops at the bottom of the left and right daisy chains (the vertically aligned straps on the front) and secure the handles with the cords attached to the top of the daisy chain. For an axe (ice axe), thread the metal part through the holder at the bottom of the backpack (the horizontal fabric pocket on the front), and secure the handle with the cord at the top of the daisy chain."

By attaching small items with carabiners to the daisy chain or adding extra straps to carry external gear, it is possible to carry more than the backpack's capacity. Adding pockets to the product increases weight and can reduce durability, but the simple "Scrambler" is praised for its lightness, sturdiness, and expandability.

"The lightweight and durable nature comes from using 400D nylon ripstop material for the main body fabric. The TPU coating on the reverse side enhances waterproof capability, making it suitable for tough environments. The side pockets are convenient for carrying bottles; however, they are made of the same material to maintain durability instead of switching to mesh."

The side pockets, made of the same color and material as the main body, are not only durable but also inconspicuous. They contribute to a clean appearance. While many simple single-compartment backpacks lack side pockets, having pockets for easy access to bottles is certainly appreciated. There is careful consideration for drainage as well.

Inside the main body, there is a pocket for a hydration pack (which many also use for storing documents or laptops) along with straps above it to hang the pack. Additionally, hanging a sub-bag from the gear loop (the black loop drawn to the front in the photo) facilitates packing.
 
"Similar loops to those located at the bottom of both sides of the main body are also present at the upper inside. This makes it easy to access frequently used gear or sub-bags hung from these loops. The top of the main body opens widely with a quick-draw cord, allowing for fast tightening. Covering it with the rain flap and securing it with the one-pull strap's hook enhances its rain resistance."

"The rear padding, which enhances comfort, is slightly firmer. It maintains space along the spine to create a pathway for air, ensuring it doesn't get stuffy. Upon closer inspection, the padding features a fine mesh. Coarser mesh allows snow to enter easily during winter, which is not a concern here. This is why the 'Scrambler' can be recommended year-round."
 
Delicate touches of practicality are found throughout. The simplicity, coupled with expandability and durability, ensures it can be customized and used for a long time. Its lightweight and usability surely contribute to its popularity, making it a backpack worthy of the title masterpiece.
