What We Like about the Osprey Renn 50 Backpack


Considering the weight and supplies this pack can carry, it offers immense comfort.

The Anti-Gravity pack structure provides comfort from shoulders to hips. And the adjustable waist and shoulder straps allow you to customize the fit to you. 

The shoulder straps adjust up to 5 inches making the torso length shorter or longer. This gives you personalized comfort, a great feature as each hiker's body is different. 

Lightweight but durable

A lightweight and durable pack is a hard combination to find. This backpack is lightweight, weighing 3.31 lbs. but remains sturdy with the 600-denier polyester and 1000-denier nylon pack cloth. 

The polyester material is durable and keeps the pack water-resistant. It also helps the pack keep its shape after washing. Nylon is used to prevent tears and rips and is an excellent waterproofing material.


One of the best features of the pack is the suspended mesh back panel. It makes the pack very breathable!

Having this back panel on a backpack allows airflow between the area of the pack and your back. This feature helps dry the sweat the hiker accumulates during their hike. The suspended mesh back panel is a game-changer on day packs as well.

What We Don’t Like about the Osprey Renn 50 Backpack

No Trekking Pole Loops

This may not be a deal-breaker for all hikers, but there are no attachment loops for trekking poles. These loops come in handy on steep terrain or when you need your hands free. However, it's possible to can use one of the side mesh pockets to store the poles.

No Fit-on-the-Fly Hip Belt

A Fit-on-the-Fly is a pad that extends up to 5 inches on the hip belt to accommodate different hip sizes. This might not be a deal-breaker to most, but it is something to consider before buying. Osprey does offer the Fit-on-the-Fly feature on their Aura AG 50 pack.

No Removable Floating Top Lid

Osprey Renn 50 doesn't have the removable top lid with dual zippered pockets feature. Once again, not a deal-breaker.

It is something to consider if you want to cut weight in your pack. By not having these premium features allows Osprey to price Renn 50 at such an affordable price.

Osprey Renn 50 Backpack Key Features

Padded Shoulder Straps

Shoulder straps are most susceptible to tears. So having the extra padding on your shoulders adds an extra layer of hefty material. Also, these shoulder straps help to reduce the strain on your back.

Rain Cover

All hikers hope for the sunshine and blue sky during their treks. Unfortunately, it isn't always the case. A rain cover does come with the pack to protect it from wet conditions.

Hydration Reservoir Pocket

Inside the main compartment, there is a pocket for your hydration bladder. There is also a small strap on the backpack strap to secure the spout of the bladder.

External Attachment Straps

There are straps located on the outside of the pack toward the bottom. Hikers can use these straps to carry items such as a sleeping bag, a tent, or any item that is too bulky to fit inside the pack.

Osprey Renn 50 Backpack Organization and Pockets

The Osprey Renn 50 makes it easy to stay organized while you are on the trail. Aside from the main compartment, it has six extra pockets, two side pockets, two hip belt pockets, two mesh water bottle pockets, a lid pocket, and a pocket on the lower back.

There is also a very small pocket located on the bottom of the pack for the rain cover. 

Main Compartment

The main compartment has top and bottom access. This is a great feature as you don't have to dig to the bottom of the pack to get something out.

The top of the main closes with a drawstring, which makes it easy to close tight and open wide. Also, the drawstring allows better leeway to store more supplies.

Sleep Bag Compartment

There is a removal divider at the main compartment. This separate compartment makes an excellent space for a sleeping bag.

Keeping your sleeping bag inside your pack prevents the risk of it getting wet from the weather. It also prevents it from ripping or snagging on anything while you trek.

Lid Pocket

There is a hidden pocket on the lid of the pack. This pocket is great to store essentials such as phones, keys, cash, or a wallet.

Lower Back Pocket

There is a zippered pocket located on the lower back on the pack. It does not connect to the main compartment. This is great for those items you want to keep separate from the main compartment jumble.

Hip Belt Pockets

The two spacious hip belt pockets are a great feature to keep your essentials during a hike - things such as sunscreen, chapstick, cell phone, GPS, sunglasses, and snacks.

Side Pockets

There are two spacious zippered side pockets– one on each side of the pack.

Water Bottle Pockets

There is one mesh water bottle pocket on each side of the pack. This feature makes it easy to grab that extra drink of water while you are trekking.

Osprey Renn 50 Backpack Fit & Sizing

One Size Fits All

This women’s pack comes in one size. But not to worry, Renn 50 offers unique, customizable features to form to your body.

Adjustable Fit

Because the Renn 50 comes in only one size, one of their key features is the adjustable shoulder pads. This means you can change the torso length.

The length of the torso ranges from 14 to 19 inches long. You can customize the length to fit your height need. Also, the fit for the waist and hip belt adjusts from 25 to 50 inches.

Lightwire Alloy Frame

With a lightwire alloy frame, this pack can absorb shock better than stiff packs while it’s inaction. This makes it more secure on the hiker’s back.

Recommended Alternatives

Osprey Renn 65 Women's Backpack

If you love all the features the Renn 50 offers but are looking for something bigger, the Osprey Renn 65 is your go-to. Weighing 3.44 lbs, this durable pack can carry up to 40 lbs. The liter capacity is the biggest difference when comparing the two, with the Renn 65 able to carry up to 65 liters.

If you are a male hiker and looking for a Renn 50 equivalent, check out Osprey Rook 50.  The Rook 50 can carry 25-35 lbs. and weighs 3.49 lbs. The pack also can be easily adjusted to fit a wide range of torso lengths and comes with a rain cover.

If you don't have a strict budget, check out Osprey Aura AG.  

This line offers more premium features such as the extendable Fit-on-the-Fly pad and the removable top lid. It offers three different sizes for men and women to choose from, ranging from 4.02 lbs. to 4.42 lbs. This pack is suitable for a week-long backpacking trip.

If you’re looking for something even lighter, check out Osprey Tempest 30

This pack is simple but ventilated and great for day hikes. It is also a lightweight choice for overnight trips. This pack comes in two sizes: a small weighs 1.78 lbs., and a medium weighs 1.896 lbs.

What to Consider when Selecting Your Backpack

First, start by determining what kind of backpack will meet your basic needs while you are on the trail. 

Ask yourself the following questions - 

  • How many days/nights will you be trekking? 
  • Is a spacious main compartment a high priority?
  • What kind of volume should the pack hold?
  • How many pounds are you expecting to fit?
  • Will you be hiking in a wet or dry climate?

Next, keep in mind a lenient rule of thumb: a loaded backpack shouldn’t exceed 20% of your body weight. For example, if the hiker weighs 150 pounds, their packed backpack should weigh 30 pounds at most.

A backpack anywhere between 50 to 70 liters of volume can manage multi-day trips.

Whereas, daypacks ranging from 20 to 35 liters of volume are suitable for overnight or day trips.
