Fully featured with a clean, simple design, the Exion 65 is a highly versatile pack that takes you wherever you want to go, from thru-hikes to multi-day treks between alpine huts. The adjustable V-TRAX™ carry system, with its thermoformed harness and dual densities of foam, ensures full contact with your back while delivering cushioning support where it’s needed and reduced bulk where it’s not. The result is a construction that keeps weight down, carries heavy loads well, and offers you instant comfort which endures over long distances. With an eye-catching embossed pattern and high-comfort, practical design, the Exion 65 is the perfect pack for unhurried miles on the trail.
A properly fitted pack makes all the difference when you’re tackling tricky terrain and steep ascents.
Your backpack should feel unrestrictive and give your body the freedom of movement it needs.
This guide is here to help you find the right size backpack for your next trip, and adjust it to achieve the perfect fit.
You can find your iliac crest by tilting your head forward slightly to find your C7 vertebra, and placing your hands on your hips. Your iliac crest is the most obvious protruding part of your 'hip bone' and where you would naturally place your hands on your hips.
Bear in mind that some of our backpacks have an adjustable back system, so you can further fine-tune the length.
Many of our larger volume packs are also available in ‘ND’ or narrow dimensions, ideal for women or those with smaller frames.
A hiking backpack’s harness is usually made up of four main parts, these are:
Hipbelt
The hipbelt is designed to securely fasten around your hips. A common mistake is to put the weight of the backpack on your shoulders and use the hip strap for stabilisation. In fact, it works the other way round. The hips need to take your weight and the shoulder straps are for stabilisation.
Shoulder straps
The shoulder straps are designed to fit snug to your shoulders, and the front of your upper torso, without restricting movement or blood flow. They should follow your natural shape and be secure enough to stop the pack bouncing around when moving, but loose enough to ensure you have a full range of motion.
Chest strap
The chest strap, or sternum strap, is simply designed to stop your shoulder straps from sliding down your arms. This is particularly helpful when wearing smoother garments, such as shells, where there isn’t much friction to hold the shoulder straps in place.
The sternum straps should be tightened enough to achieve this, but it should not restrict your breathing or freedom of movement.
Load lifter strap
The load lifter strap is the small strap that connects the top of the shoulders to the upper construction of the back system on your backpack. If you loosen the straps, the top of the pack will move away from your body, and if you tighten them, the top of your pack will shift towards your body.
This helps to centre the weight of your pack towards your body, which is useful if you have a lot of weight at the top of your pack.
Achieving a comfortable fit involves adjusting all four parts of your harness. Here’s how to do it:
Load up your backpack with as much weight as you expect to carry for your trip. This way, you’ll ensure your pack is fitted with your load in mind and there are no surprises on the trail.
Adjust the back length using the mechanism provided (if it has one). Measure the pack from the base to the middle of the shoulder straps. This should roughly match your back length measurement.
Loosen all the straps described above and put the backpack on over your shoulders.
Start with the waist strap, securing it so the top of the hipbelt sits about 1” above your iliac crest.
Pull the waist strap to adjust it, until you feel the weight of the pack rest on your hips. The fit should be snug but not too tight, and support the weight of the pack without sliding down.
Now pull the webbing on the shoulder straps to bring the backpack up and in towards your back. The shoulder straps should feel tight enough to hold the pack in place without any movement, but they shouldn’t restrict your mobility.
Gently adjust the load lifter strap to bring the pack weight into your back. Stop pulling before you feel the weight lift off your hips. This feature is especially useful if you have a heavy load and want to pull some of the weight into your centre of balance.
Finally, fasten the sternum strap, and gently pull it in.
The maximum weight you can comfortably carry is really a matter of personal preference and depends on the distance and type of terrain you’ll be covering. However if you’re worried about overfilling your pack, here is our suggested load range as a guide:
| Backpack volume | Suggested load range |
|---|---|
| 5-30 L | 0-16kg |
| 30-50 L | 7-19kg |
| 50-80 L | 12-28kg |
