Type of backpack: daypacks
Daypacks are the most common types of backpack, designed to be used for anything from popping to the shops to carrying technical gear for a big day in the mountains. The capacity of daypacks range from around 10-40 litres, depending on what they are needed for.
Hiking daypacks
A full day hiking out on the trail requires you to carry plenty of water and enough food to keep you going. Your hiking daypack will also need to hold extra layers and a rain jacket. But most importantly a hiking daypack should be comfortable.

Climbing daypacks
As well as the gear you need to carry for hiking (water, food, layers etc) a good climbing backpack also needs to be able to hold a rope, helmet, harness, rack and shoes. And ideally it needs to be comfortable and close fitting to your body.

Cycling daypacks
The capacity of a cycling backpack depends on how long you hope to be out for. A couple of hours and you can get away with a hydration pack with limited storage. But a big day out on the trails requires you to carry tools, repair gear, extra layers, food and plenty of water. A good cycling backpack should also be comfortable and well ventilated, and not move around too much when loaded.

Snowsports daypack
The capacity to carry your skis or snowboard is the most important feature to look for in the pack you choose for a day on the slopes. Minimal movement of the pack is also really important, so it’s important to choose a pack that fits you snugly without limiting your movements.

Sightseeing daypack
Although it’s important for a sightseeing daypack to be comfortable, it’s not as important as when you are more active. And it’s unlikely you’ll be carrying a heavy load so you can afford to choose something more lightweight than a full-featured hiking backpack.

Type of backpack: large overnight backpacks
For those heading out on grander adventures, a backpack that is big enough to hold your overnight stuff will be needed. As with daypacks, backpacking backpacks can vary greatly depending on your needs, circumstances and preferences. Their capacity can range from around 40 litres to as big as 85 litres.
Hiking/trekking backpacks
Choosing something comfortable and well-fitting is really important when you are carrying heavy loads. But it’s also good to have a hiking backpack with features that make is easy to use. The capacity of your backpack for hiking and trekking largely depends on the length of your trip. Here’s a rough guide to what you might need.
- 1-3 day trip = 40-60l
- 3-7 day trip = 50-75l
- 8+ day trip = 65l+

Lightweight hiking backpacks
As the backpacking world moves closer and closer to embracing ultralight gear, it’s much more do-able to pack all your gear for multi-day hikes into backpacks that are under a 50 litre capacity. Thru-hikers and long distance trekkers often opt for the ultralight way of hiking, aiming to keep their backpack capacity somewhere around the 40-45 litre mark.

Travelling backpacks
For those off jet setting for months at a time, a less technical backpack is required in most cases. Generally, travellers will need to haul their loads for a couple of hours at a time, max. So comfort is less important compared with hiking backpacks. The main focus for this style of backpack is storage options, adaptability and convenience.

Ideal capacity: 45-80 litres
Desirable features:

Type of backpack: hydration packs
If you prefer getting out into the wild in a more active kind of way, hydration backpacks are an ideal solution that turn minimalist adventurers into veritable camels! The capacity of hydration backpacks is usually between 2 and 10 litres, with 1, 2 or 3 litres of that space taken up with a hydration reservoir. They need to fit very snugly to minimise movement, but also be highly comfortable.
Running hydration packs
Many long distance trail runners opt for hydration vests – an evolution of a backpack that spreads the weight of the water and focuses on easy drinking access whilst on the move. But there are also some great low profile hydration backpacks around that many find equally as comfortable and user friendly as a hydration vest.

CamelBak Octane Dart
Amazon | REI | Backcountry
Ideal capacity: 3-5 litres
Desirable features:
- Very comfortable
- Close fitting
- Good ventilation and breathability
- Lightweight
Cycling hydration packs
There is a lot less body movement when cycling, compared with running, so hydration packs for cycling can afford to have a greater capacity – if needed. Comfort is important, but having a good system to easily access the hydration hose when on the move is key.

Other types of backpacks
Dry packs/waterproof backpacks
Fully waterproof dry packs are used in a variety of scenarios, so their capacity can range hugely depending on their intended use. A 15 litre dry pack for cycle commuting is ideal in wet weather. And on the opposite end of the spectrum, those on larger scale water based adventures will require the big 120 litre dry packs to store and haul all their stuff with zero risk of it getting wet or damp.

Sea to Summit Hydraulic Dry Pack
Sea to Summit | Amazon | REI | Backcountry

- Shoulder straps, waistbelt and sternum strap
- Made from durable PVC or TPU/PU
- Internal storage pockets
- External mesh pockets for wet gear
- External gear loops
Packable backpacks
Having a backpack that is highly packable is a very appealing option for long distance backpackers, travellers and sightseers. With minimal padding and support they are not the most comfortable bags, and are not suited to carrying heavy loads.
