This is a fantastic bit of kit! Looks and carries like a Backpack, but loads like a suitcase.
The back system is really good and the perfect fit is easily achieved. Also unlike any other backpack I've known, there are zip mesh pockets on either side for those small items that get easily lost amongst what's been packed and shifted, after rummaging for something at the bottom of the bag. Although that isn't an issue either, because the whole back of the bag has a zip surround, meaning everything is easily accessible whether at the top, middle or bottom of the bag.
The top of the bag is a bag in itself and separates easily from the main bag. This makes it ideal for trips to the shower block when staying on site.
The outer pockets are of a generous size, and ideal for carrying 1l sports bottles. The belt pocket is a good size too with a decent zip allowing it to open fully. This comfortably houses a mobile power pack, and allows a charge lead to be connected to a mobile device whilst on the move.
The lower compartment is accessible from both inside and outside of the bag, and at the bottom of the bag there's a pocket for the included cover. This though is no ordinary cover. It also can be used as a separate bag. Again, ideal when on site, and needing to maybe do a bit of laundry. It can also be used to carry the backpack itself over short distances, or when on public transport, so as to avoid the need to carry it awkwardly or struggle in a confined space to put it on.
All in all this ticks all the boxes, and I highly recommend it.
Great design and quality of fabrics.
A lot easier to access things with the ability to open like a suitcase.
Comfortable to wear when full (of clothing).
Included raincover is handy for keeping it all together when flying.
It not only has the best volume-to-weight ratio, but also smartly designed to fit in all the necessary travel supplies in the most efficient manner.
I recently used this product in Goechela trek. Though slightly bulky but it is awsome, comfortable.
I think I am one of the very first customers in India to buy this bag as soon as it arrived in Hyderabad Decathlon store. Well, There should have been a "Very Good" between your "Good" and "Excellent" rating. I am rating it as "Very Good" as it serves all purpose of a trekker, camper and traveler. The back open system like a suitcase has made it unique in design, and it's a delight thereby using the product. The top portion of the bag can be used as a side-satchel - that's another great feature. Though a locking mechanism doesn't help much in terms of security in this kind of backpack, I must say, it's a unique feature and definitely a plus.
The only downsides I found are that the bag is quite heavy, even when it's empty and that the rain cover that comes with it is also very heavy and takes a good amount of space, even after folding up neatly. The rain cover, I feel, could have been little thinner, like a light plastic one. If you are a serious camper like me and are carrying your tent / sleeping bag etc along with the bag, it may be a bit heavier while ascending steeps.
Else, a fantastic product.
Comfortable and roomy and has a very handy day pack that attaches to the backpack. Open to the front so it's easier for packing. Used it for 2 weeks while backpacking in Europe and was very happy with it!
Disclaimer: I only used this for a few days.
I loved the convenient packets and lockable main compartment. Overall awesome bag. However, I did notice it is around 2x heavier than my main 70L bag. In the end this weight issue was a deal-breaker for me, although I loved everything else.
