I also loved the extra padding on the straps, which makes it comfortable to carry - it is the best small climbing backpack I've ever used. There's a compression strap at the top, which is linked by two compression fasteners, and together they create a tremendous rope-carrying structure.

What's more, there is a small zip pocket and a chain to complete the set at the front. The PETZL Bug backpack has a compact build, and my 15-inch screen laptop fits well in it. This is a good choice if you need a climbing backpack to cope with your everyday duties.

While this amazing climbing backpack features extra-thick fabric on the top, bottom, and sides, most of the body has a thinner material. This is handy in reducing the backpack's weight, though it may reduce sturdiness.

When it comes to price, the PELTZ Bug is quite affordable, and it is worth buying if you're looking to buy a comfortable, flexible, and good-looking climbing backpack. It fit securely on my back due to its compact build, and the additional pockets on the exterior and interior are an incredible bonus.

Quick Facts:

  • Capacity: 20 liters;
  • Drawstring & hook are the main closures; 
  • Weighs 27 ounces .

Despite its ample size, you will hardly feel it on your head. That's because, like And that's not all; it also features an incredible suspension system, among other handy features. It has a drawstring liner which creates additional room if you have a lot of gear to carry with you.

Also, this climbing backpack handles your luggage quite well. The compression straps allow for easy management, while the sides feature several gear loops. The Mountain Hardwear multi-pitch backpack has multiple attachment options, making it perfect for fitting all your items and climbing gear.

It has many features, like its compact design and one additional external attachment option for the Ice ax. The central opening is reliable and extremely user-friendly. It is made of a lightweight fabric that does not resist abrasion well. 

Additionally, this alpine climbing backpack only has one external attachment option for the Ice ax, making it hard to manage the gear that could get strapped on without creating the attachment points with the carabiners and strings by yourself.

However, I found that the shock-cord featured on the pack makes it more difficult to utilize this pocket fully.

Climbing Bags FAQs

Top Rated Climbing Packs

What size backpack do I need?

There are several sizes of climbing backpacks, and the size you need depends on the gear you're carrying.

Here are the different backpack sizes:

1. Hydration packs

Hydration backpacks are for people who like long, climbing routes in unwavering weather. They are built to be more superior to rock climbing backpacks.

They are smaller than the other types of climbing backpacks, and they exhibit a narrower build that makes them easier to climb with. On the other hand, these advantages come with drawbacks. Typically, they are not spacious enough for shoes or additional layers. 

Besides, they are less durable. Still, I prefer hydration packs during the sunny, tedious routes when I need water but don't want the inconvenience that comes with a full-fledged climbing backpack.

2. Rock climbing backpack

The rock climbing backpacks are small, mostly with a capacity of 12 to 24 liters, and they are constructed to sit high on your back so it won't hinder a harness.

Moreover, they are more durable than the standard backpack, mostly made using fabric that will easily resist abrasion. Most rock climbing backpacks feature detachable parts which allow you to customize them depending on your needs. 

Additionally, the best rock climbing backpacks also feature reinforced anchor points for intermittent hauling. Hiking backpacks can be suitable for the climber who infrequently climbs longer routes though you will have to sacrifice durability. 

3. Mini Haul packs

This is another suitable option for handling strenuous routes. It could be the best backpack to go for on difficult-to-climb routes. A mini haul backpack has a carrying capacity enough for a day's worth of tools, which is quite impressive.

Besides, if you utilize a capture pulley and a tagline, it becomes easier. Additionally, I like this type of backpack since it is spacious enough to keep the aid gear packed until you require it.

4. Mountaineering and alpine packs 

When the slope becomes steeper and the temperatures drop, climbers have to wear additional gear to stay comfortable. Climbing with an alpine backpack is more suitable for this situation and because an alpine terrain makes carrying it more convenient.

Alpine climbing backpacks can be lighter since abrasion is not an issue in snowy surroundings. They usually have a bigger construction to accommodate the heavier insulating layers.

Out of the five climbing backpacks I've reviewed here, the Black Diamond Blitz 20 and the Arc'teryx AR 20 are constructed purposely for alpine climbing.

What consider when buying a rock climbing backpack?


This climbing pack's size you buy mostly significantly depends on the type of climbing you partake in. When it comes to rock climbing-specific daypack, you require one with a capacity of 16 to 20 liters which is more than enough to carry layers, snacks, or food and water.

Sport vs. Trad

For rock climbers, go for a durable backpack that is extremely abrasion-resistant. Rock climbing involves bolted routes, and it requires a tougher bag like our top pick PELTZ Backpack 18.

Streamlined or Junk show

Ensure you go for a rock climbing backpack that has several options for attaching a rope, a water bottle, as well as other necessities. Also, ensure that the tools attached to it are not dangling around. Make sure you pack most of your rock climbing necessities inside the backpack.

However, you can carry the rope on the outside since most rock climbing backpacks will not have enough space to accommodate it, depending on the number of tools you're carrying.

Consider the number of times you will require strapping gear on the outside and look at every pack's available attachment points.

Climbing Backpack Features 

Haul points 

The Mountain Hardwear 20 features two durable loops designed for rock climbing. On the other hand, the single-haul loop could also be efficient for most rock climbers. You can also create additional haul points utilizing other attachment options or the shoulder straps, a rope, and a bit of creativity.

Hip belts 

Choose a rock climbing backpack with at least one removable hip belt. Also, you can go for one with a permanently attached hip belt.

Emergency whistles 

Rock climbing daypacks should have a safety whistle. They are compact and light and can come in handy as a signaling device in times of emergency.


While this is crucial for any rock climbing backpack, it is relatively difficult to explain in theory. After choosing the rock climbing-specific backpack you need, check if it fits. Your backpack must fit your back length. The lower part of the backpack is supposed to be above the hips.


Hopefully, my guide will help you find the right climbing backpack to help make your adventure more comfortable. The PETZL Bug Climbing Backpack 18L is durable, versatile, and good-looking.

Additionally, it is spacious and durable enough to resist abrasion during your adventure, which is why it is our top pick! Besides, if you need a climbing backpack that will cope with your everyday duties, it is the perfect fit.
