What is a Backpacking Backpack?

A backpacking pack is a large backpack designed to carry your gear on overnight trips. They are generally between 50 and 110L in size.

The capacity you choose for your pack depends on the length of your trip and the season you’re backpacking in. For example, the Arc'teryx Bora AR 63 has the capacity to carry enough gear for trips between 4-7 days.

Backpacking packs differ from day packs in terms of size. Yet, you’ll find some features on a backpacking pack that are not included on a day pack. Such as extra straps for sleeping pads. 

Why are Osprey Backpacks Good Value?

Osprey is one of the oldest backpacking gear manufacturers in the United States. 

They are known for making high-quality equipment that’s very versatile. We love that Osprey builds their packs with plenty of features to make your life easier when you’re out and about.

Plus, Osprey stands by the quality of their packs. They offer their All Mighty Guarantee.

The company will repair any damage or defect on their packs, free of charge, regardless of when you bought it. 

Should I buy a Gender-Specific Backpack?

These days, it is possible to get a women’s specific backpack. Having “gender-specific” hiking packs may seem odd.

However, many women’s models are better suited for people with smaller bodies.

A women’s pack will usually have a shorter length, which is better for people under about 5’9” (175cm) in height.

Additionally, these packs usually have wider hip belts and curved shoulder straps. These adjustments are to accommodate a woman’s body better.

How to Pick the Right Backpack?

A backpack is a critical piece of gear when it comes to hiking. Thus, it’s vital that you fully understand what you are looking for before you buy.

So, when shopping for your next hiking backpack, here are some of the main factors to consider:

Intended Purpose  - When we buy a piece of outdoor gear, we usually intend to use it for a specific purpose. In particular, backpacks come in many shapes and sizes. Some of which are best suited for a specific activity.

Hike Duration - A day hike can be as short as half an hour while a backpacking trip can last for months. The length of your hiking trip will have much impact on the pack you choose to use.

Comfort - Comfort is key when it comes to buying a hiking backpack. Keep in mind you’ll carry your pack over varied, uneven terrain for hours on end. You don’t want to purchase something uncomfortable.

Capacity - Backpack capacity is traditionally expressed in terms of liters of volume. In general, the capacity of pack that you need is dependent on three things: the length of your trip, the season, and the type of activity.

Here’s a rough guideline for choosing your pack capacity:

  • Summer day hikes: 10-30L
  • Winter day hikes: 30-50L
  • Summer backpacking trips: 60-90L
  • Winter backpacking trips: 75-110L
  • Extended (14+ day) expeditions: 90-110L
