How to Choose the perfect Hiking Backpack for your Adventure
Your next adventure is calling, and before you head out, choosing the right hiking backpack is one of the most important decisions you’ll make. The right pack improves comfort, balance, and enjoyment on the trail, while the wrong one can quickly turn a great hike into a struggle.
In this guide, we explain how to choose a hiking backpack by looking at volume, fit, frame type, and essential features. Whether you’re planning a short day hike or a multi-day trekking adventure, this guide will help you find the perfect backpack for your needs.
1. Choosing the right volume
Backpack volume is measured in litres and determines how much gear you can carry. The right size depends on the length of your trip, season, type of gear, and your personal packing style.
| DURATION OR DISTANCE | RECOMMENDED SIZE | WHAT IT FITS | RECOMMENDED COLLECTION |
|---|---|---|---|
| Day Hike (1/2 - 1 Day) | 15 - 25 L | Water, snacks, light jacket, first-aid kit | Nano, Kiro |
| Full-Day Hike / Winter Day | 20 - 35 L | Extra layers, food, hydration system | Arrio, Zulu LT & Jade LT, Citro & Juno |
| Weekend Trip (1 - 3 Nights) | 35 - 50 L | Sleeping bag, compact tent, stove, food | Zulu & Jade |
| Multi-Day Hike (3 - 5 Nights) | 50 - 70 L | Shelter, cooking gear, clothing, food for several days | Paragon & Maven, Stout & Amber |
| Multi-Day Hike Remote | 60 - 100 L | Bulky gear, 4-season tent, insulated cooking, extra food | Baltoro & Deva |
Expert advice:
- Ultralight hikers can often manage with fewer litres if their gear is carefully selected.
- Winter hikes require extra space for gear. Plan for an additional 10-15 litres.
- Family trips often require significantly more space, as you’ll also be carrying children’s gear. Plan for extra-large backpacks in this case.
- Many people tend to pack a lot, so choose wisely what you bring or add a bit more space.
2. Choosing the right model
Once you’ve selected the right volume, the next step is choosing a backpack model that matches your hiking style. You will have to decide whether you prefer a backpack that fits close to your body for maximum stability, or one designed with ventilation in mind for better airflow in warm conditions.
Close-to-body
Close-to-the-body backpacks are ideal for those who prioritise stability and comfort on challenging terrain. They keep the load close to your centre of gravity, reducing strain and improving balance.
Gregory’s Air Mesh technology allows airflow while maintaining a close, supportive fit. Collections such as Miko & Maya are designed for stability, comfort, and confident movement on the trail.
Ventilated
Ventilated backpacks are designed to maximise airflow between your back and the pack. A tensioned mesh back panel, supported by a perimeter frame, creates space for continuous ventilation.
These backpacks are ideal for warm climates, long summer hikes, and high-output activities. The Zulu & Jade collection is a great example, combining effective ventilation with all-day carrying comfort.
Internal Frame
Internal frame backpacks feature a lightweight frame built inside the pack. This design keeps the load close to your body and distributes weight efficiently across your hips and shoulders. Internal frames are ideal for: Multi-day hikes, Backpacking trips, Carrying heavier loads, Steep or uneven terrain.
The Baltoro & Deva series is a prime example, offering outstanding support, balance, and comfort on long-distance adventures.
Frameless
Frameless backpacks are lightweight and flexible, without rigid structural support. They are best suited for ultralight hikers and short trips where speed and agility matter most.
If you’re heading out on a short day hike or travelling with minimal gear, a frameless backpack like the Nano series offers simplicity and freedom of movement.
3. Backpack fitting: Why it’s crucial
A well-fitted hiking backpack improves comfort, reduces fatigue, and allows you to carry weight more efficiently. Proper fit ensures the load is distributed correctly, helping you hike longer and feel better throughout the day.
Men’s, Women’s & Specialised Fits
Backpacks are designed differently for men and women due to variations in torso length, shoulder width, and hip structure. A gender-specific fit improves weight distribution and stability.
We offer backpacks for: Men , Women and Youth
Backpacks also come in different torso sizes. Choosing the correct size ensures the majority of the load rests on your hips rather than your shoulders, essential for comfort on longer hikes.
4. Essential features
Comfort & Carry System
Comfort is the most important factor when choosing a hiking backpack. Once you’ve selected the right volume and size, proper adjustment is key.
Ideally, about 70% of the weight should rest on your hips, with the remaining 30% supported by your shoulders. As pack weight increases, fit and suspension become even more critical.
Some Gregory backpacks feature 3D pre-curved shoulder harnesses and hipbelts, designed to follow your natural body shape and reduce pressure points. The Paragon & Maven collection offers excellent carrying comfort for long days on the trail.
Pack access
An important feature of a backpack is how easily you can reach your gear inside it. There are multiple different options. Here are the most common ones:
- Top-loader: Secure and simple, but access to the bottom can be limited
- U-zip or panel access: Full access from the front of the pack
- Side Zipper: Allows full access from the side.
- Sleeping Bag compartment
For day hikes, simple top or panel access is usually enough, but for multi-day trips or technical adventures, having multiple access points can save time and reduce frustration. Choosing the right pack access depends on how organized you want your load to be.
Pockets and organization
Good organisation makes a big difference, especially on longer hikes. Well-designed backpacks include a mix of internal compartments, external pockets, and mesh storage.
- Hipbelt pockets for snacks or GPS devices
- Side pockets for water bottles
- Internal pockets to separate clothing and gear
- Hydration sleeves for water reservoirs
Minimalist backpacks reduce weight by limiting pockets, making them ideal for ultralight hiking.
Hydration reservoir
A hydration reservoir allows you to drink without stopping, helping you stay hydrated on the move. Many hiking backpacks include a dedicated reservoir sleeve and hose routing.
For long or hot hikes, a hydration system is highly recommended. Gregory also offers features such as magnetic bite valves to keep the drinking hose easily accessible at all times.
