This is the Deuter Quantum 70 + 10 Convertible travel pack. Really great capacity in the pack for long trips as it has a detachable front pocket that can be used as its own day pack, an integrated rain cover and transport cover and lots of features that make it ideal for travel. You can see that the Quantum is equipped with a nicely padded suspension system with padding in the lumbar and padding up through the back, also in the shoulder straps and a really nice padded hipbelt. There is a laddered system here at the back with a quick velcro system to make adjustments with, to best fit your torso length. There are load lifter straps here and straps throughout the hipbelt as well to help you really dial in that fit. Deuter also build s a smaller version of this pack, the Quantum 55 + 10 SL which is a women’s pack, and what really differentiates the two , other than it being smaller in size, is the placement of the harness system and also contouring in the hipbelt which make it a more ideal fit for most female users. Turing the pack around you can see it looks like a traditional top loader with a large lid and large front pocket. This is a removable front pocket and I’m going to go ahead and actually get that out of the way for the moment so we can look at the main pack body. There is a lower zippered sleeping bag compartment, again similar to a traditional styles backpack, but more similar to luggage there is also a very large, peel back, front panel access that get’s you down into the main body of the pack when laid down like a piece of luggage, again, more similar to a suitcase. So looking at that removable front pocket, really nice functionality in this piece, it cleaned up the profile of the main pack bag which in certain instances might be helpful and you are probably checking this bag at the airport or if you are travelling by rail and it is also a big large for day-n day-out use if you’re using this for hostelling purposes. So, you may leave it behind and use a day pack which is what you’ve got here. Turning this around you can see it has its own integrated shoulder straps with some padding on the back panel, a pocket on the front and interior pocketing as well. There is also some expandability on this via a zipper that runs the entire way around the pack and when opened up allows this to expand a bit and gives you some more room. Keeping it cinched down keeps both packs more compact when you don’t need the extra space. A stand out feature of the Quantum packs it tucked away at the very bottom of the pack bag itself. You’ll see some stitching here that indicates that the transport cover is tucked in underneath in its own integrated transport/rain cover which I have already pulled out and we’ll put that over the quantum pack now. So I’m closing the transport cover. If this is left opened and peeled down it serves as a rain cover and you can still put the pack on while the shoulder straps peek through but when you are checking or loading this somewhere, you’ll want to close that entirely and cinch it down tight and securely. You can see there is an integrated identification piece here for your contact information and there is also haul handles here which again make this a really great option for travel.
