First of all, I would like to say that I am very happy with the backpack and I am 1.93m tall, so I am certainly not the average person, but I still paid the full price. I use the Shelter Backpack in olive green, the waterproof daypack, the sealed laundry bag and the roll-up toiletry bag. Now to the product review, I have been using the backpack very intensively for about 2 months now and there are a few points that simply have to be said, as it is not just a backpack, it is the most expensive backpack on the market. First of all, it has to be said that the people at Tropicfeel really put a lot of thought into it and have brought a very versatile and well thought-out product onto the market. However, it must also be said that, in my opinion, the product is partly of too low a quality for the price, the functions have not yet been perfected and the price is therefore simply far too high. The specific points are as follows: 1. when wearing the daypack, you sweat extremely on your back, as it is not breathable at all, but it is also not possible, as you have to strap it so tightly so that the resting surface rests on your shoulders and is not on your back. (Suggestion: as with a "normal" rucksack, simply make the shoulder straps longer, as the back surface is just a little too short) 2. the daypack is extremely frayed at all seams, I'm not sure if the daypack will last long, as it already looks very worn at the seams (reminder: I've only been using it for 2 months, hopefully the warranty department will fix it if I make a complaint) 3. now to my biggest complaint, the shoulder straps of the Shelter Backpack are quite wide, but they are not padded. This is an absolute no-go for a backpack costing over €400, as you can get better quality backpacks for around €90. To be fair, it has to be said that you usually only wear the rucksack for a short time when it is fully loaded, as you then get on a plane or bus etc. and drop off your luggage. But there are also other days when you have to carry the fully loaded backpack around for longer and that is really not good with this backpack because, as I said, it is simply not padded and hurts if you carry it fully loaded for longer than 30 minutes. 4. the idea of attaching the daypack to the back behind the shelter is nice, but simply not practical, as the whole construct loses its center of gravity completely and you always have to walk bent forward, which is not possible (Severe back problems are pre-programmed) Fortunately, there are two loops attached to the shoulder straps, which make it possible to attach the daypack to the front, so it's super usable and makes a lot more sense as you also have access to some items. Unfortunately, the loops are attached to the outside of the shoulder strap, so the daypack pulls extremely inwards when you attach it there and it hurts again after a certain time. (Still the best option you have!) (Suggestion: Attach the loops to the inside of the shoulder strap and test how you can best solve this problem so that it no longer hurts and you can comfortably attach the daypack to the front of the shelter). All in all, I can recommend this backpack 100% if you have a high budget, but if you want to travel very cheaply and are looking for a price-performance champion, this backpack is simply not ready yet. That will take some time. But I am confident that the people at Tropicfeel will take the review to heart and try to solve everything and improve. I don't regret buying the backpack because it is simply incredibly versatile and I really enjoy using it!
