Is there a sizing chart for backpacks?

Which size should i choose? During several field test sessions with hikers of different sizes, we noticed that between 20 and 40 liters, the difference in comfort was mainly down to the back height of the bag. We therefore offer all our models in 2 sizes to meet these requirements. If you are taller than 67'', go for size L. If you are shorter than 67'', you will be better off with a size S.
Question:
Per your sizing info, if taller than 67", you recommend size large. I am 5' - 8" is 68". Shouldn't I be large size?
Answer:
We recommend a size L for you.

Product Customer Reviews

OK
Not practical, not sturdy, some straps broke on first use.
Excellent backpack in all aspects, comfortable, spacious, well organized and with easy access to cargo.
the backpack was comfortable and roomy, but unfortunately after a few trips to the mountains, the material began to crumble from the inside.
Good, convenient to carry.
Vgy
Fg
I have carried it on my back twice when I went abroad. It is breathable and can be contracted in a small area, which is very convenient. I will carry a small foldable 10L backpack with me as an alternative when traveling.
Alright
Used as cabin baggage (regulatory dimensions): easy to take on the commuter train, on airport transfers, then can be slipped under the front seat on the plane.
Lightweight and easy to carry, the functional design is quite practical
Good value for money
Comfortable and good on the back
Very practical with very clever new pockets! Comfortable to carry with numerous adjustments.
The zip of the quick access pocket is located on the strap side. When the bag is placed on the ground (usually straps against the ground) all the belongings in the upper pocket fall to the ground

10-year guarantee
We take care over abrasion resistance to make your bag durable.The heavy clothing R&D department, a Quechua partner for the research and validation of its components and assemblies, performs tests (on components, seams and the finished product) simulating the ageing of backpacks. Their results allow us to guarantee the bags tested for 10 years from the purchase date shown on the receipt.
Don't throw it, fix it!
Our products will join you on your mountain walks. As you progress, they age, and some parts can get worn or break.To make repairs easier, in the ”Bag accessories / hiking trekking”, we sell tightening buckles and chest clips that are compatible with your bag. Don't throw away, repair !
What differences are there with the old mh500 bag?
The back of this new bag has been fully reworked for greater comfort: a tight net with frame gives you more space between your back and the bag to reduce the damp back effect. This net used for the back, called mesh, is also softer than previously. What's more, this new model comes in 2 sizes for small and large sizes. The 2 hip pockets are more spacious and stretchy and access to flask on the sides is easier.
Which size should i choose?

We therefore offer all our models in 2 sizes to meet these requirements. If you are taller than 67”, go for size L. If you are shorter than 67” cm, you will be better off with a size S.
Hydration
This bag can hold 1 liter, 2 liter or 3 liter pockets. However, although the pocket is voluminous, it will take up place that could be used for storing other belongings.The side pockets are designed for flasks of maximum 1 liter.
Why are our rain covers orange?
This is a deliberate choice as we believe it's important to stay visible in the mountains, even in fog, in case of any problem. This orange colour has the advantage of being visible from a helicopter. It's also a visible color on the road if you use your bag when cycling.
Hand luggage
When you are travelling by plane, the authorized hand luggage size is 55x35x25cm3 maximum (warning, this can vary depending on the airline). This bag can be used as hand luggage, so long as you don't load the top too much.
How to pack my backpack?
AT THE BOTTOM of the bag, pack your sleeping material, and heavy material nearer the back. Slide your water pocket into the compartment.AT THE TOP of the bag, store your waterproof jacket and fleece within arm’s reach. In the pockets, you can put your sun cream, maps, cap and sunglasses. Cereal bars or your mobile phone can be stored in the belt pockets for quick access. The straps under the bag can also be used to attach a compact tent.
How do i adjust my backpack?
1 - Loosen all the straps: shoulder straps, belt, load-adjuster straps (these are the small straps above the shoulder straps)2 - Put on the bag. 3 - Close the bag's belt, positioning it at the hips then tighten it until it feels firmly in place 4 - Tighten the bag’s shoulder straps 5 - Tighten the chest strap (not too tight to affect breathing)6 - Adjust the load-adjuster straps (the bag will cling closely to the shoulders)
