The backpack from Teton Sports is best for those newbie hikers who just started to explore the hiking trails. 

The backpack is capable enough to give an idea about how to carry and manage hiking gear with some very basic functionality. 

If you are a beginner so you can go with this best-seller backpack to gain the initial idea at a very low price after that you can go with the above-listed top quality and highly functional backpacks to use their innovative and numerous functions.

As Expert Reviewers, we find its suspension is poorly designed which failed in proper weight management. 

The shoulder and hip belt straps are made with low-quality fabric that feels very uncomfortable while wearing and taking off the backpack.

The backpack is top accessible and its top lid is difficult to access and bottom zippers are covered by an elastic flap that makes it hard to open. 

We find it difficult to put 1 liter of water bottles inside the side mesh pockets and its hip belt has no space to carry some needy small items.

Overall the backpack is not much adjustable and not so comfortable to carry a heavy load but for beginners and for short hiking trips this is the best budget backpack to try.

Detailed Buying Guide And FAQ

If you are planning your next adventure trip for climbing Mount Rainier then having all the necessary gear to deal with the tough weather conditions is a must.

And to organize all the needy things in one place you need a sturdy, comfortable, fully adjustable backpack that has a decent suspension mechanism. 

Normally choosing the right backpack totally depend on 

For how many days have you planned your trip?

What Size Pack Do I Need For Mount Rainier?

If your intention is to reach the top and back to the parking spot on the same day then you can definitely go as light as possible and in this case, a backpack with a capacity of 40L to 50L works great for you. 

If you are on a guided trip then also you don’t need to overstuff your backpack as guides take care of such things.

If your trip is 3 to 4 days long then a 60L backpack with all the latest features (Granite Gear) makes the job done with ease. 

If you are on an unguided trip and are planning for a 3 to 4-day climbing trip still this backpack performance is amazing. 

If you want to explore the beauty of Mount Rainier fullest then you have to plan at least a week-long trip for that. 

In this situation, you have to carry lots of gear like a stove, rain gear, jackets, tent gear, sleeping pads and bags, foodstuff, water, ice tools, etc.

What To Pack For Mount Rainier?

If you are on a guided trip then you don’t need to worry about anything. 

The company provides you with a list of what to keep or what to not.

This packing list is prepared for unguided trips,

Climbing Gears List

  • Climbing Helmet
  • LED Headlamp
  • Sleeping bag & pad
  • Climbing shoes
  • Backpacking tent

Do I Need Crampons For Rainier?

Crampons are one of the most essential elements for mountaineering like Rainier. 

There are two types of Crampons available in the market:

  • Aluminum Based Crampon
  • Stainless Steel Based Crampon

An Aluminum-based crampon is just half the weight of a steel-based crampon. 

Aluminum-based crampon is considered by those climbers, who want to save each gram from their pack. 

Those who want to climb as lightly as possible use Aluminium Crampons but the main downside of such crampons is they can easily bend and break and I will not suggest using them for climbing. 

Not good for any route on Mount Rainier. 

On the other hand, a steel Crampon is a very strong and trustable piece of equipment for your safety on the mountain. I usually prefer steel although its weight is high that is the thing that must be sacrificed for safety purposes. 

How Dangerous is Climbing Mt Rainier?

If I tell you that there is no risk in climbing Mt Rainier then this is totally the wrong information. 

Every mountaineering trip is full of dangerous spots, it depends on you and your training, and how well you can tackle the dangerous situation. 

If you have proper training and have all the safety gear then the chances of a happening unintentional incidents are less but still, there is a risk. 

Every year more than 100 people dead on a mountaineering trip due to Avalanches, rockfalls, and steep snow slope is also a big cause for such indicated. 


If you are planning for an Adventurous Mount Rainier journey on your upcoming trip then this article really helps you to choose the right backpack that can enhance the overall experience of Your Mountaineering trip. 

I would recommend you choose the Granite Gear 60L, which is a perfect mountaineering backpack right now. 

This is one of those backpacks that haul heavyweight almost unnoticed by most of climbers. 

Otherwise, you can choose Osprey Aether Or Atmos. Aether is good in customization, comfort & support, and accessibility while Atmos is lightweight and its fitting mechanism is better than Atmos. 

If you are on a tight budget then go with Teton Sports 4000.
