I am impressed with the quality of materials involved with this design. Perfect for those that like organization, each pack can be prepared and ready to go, easy to switch the pack to the harness. If you need a new pack to do all sorts of crazy things outside, try this one!

This is a great quality backpack. Customer service was very helpful with my questions and shipped fast.

I bought the entire bundle and love this transformative product! The quality is top notch and the materials, fabric and attention to details is amazing. 5 stars for me

As someone into hiking and Biking, i bought the duo bundle. What a unique concept. Materials are top notch.

Was able to test it out during the weekend, mainly with the mountain pack. Even without using the raincover (which is included in the mountain pack and the bike pack, but not in the ski pack), it held off enough rain to keep the inside dry (at least for about an hour in the rain).

The freedom of movement with my arms and shoulders was unprecedented. So for climbers who use their arms and shoulders a lot, this is great.

Loading it up with a lot of weight (just to test it out) wasn't so comfortable; the weight was pulling heavily on my chest (at least not on my shoulders as in some of the competitions products). So if you are not a minimalist, for longer tours I would recommend something else. For a day out in nature with not too much weight, it's the perfect gear.

I did the first hike -> selected the bikepack in order to test the maximum load if the smallest option.

The X-harness is amazing!

You feel the load of backpack on completely different points.

And yes receive another level of freedom.

The only cons -> if you untie the X-harness -> the backpack start pulling behind. My perception is that I didn't succeed to fix properly the shoulder-straps so I will play again.

If the X-harness is tied -> everything was perfect even with full backpack.

The bike pack is perfectly OK for 1day hike when you want to be with as small weight on your back as possible.

I bought the Mountain_pack backpack version and I am an enthusiastic user of it. It's perfect for my purpose, it's very useful when I have the necessity to take with me three lens and my camera. I promote it whenever I can on my social network.In the future maybe you can try to produce a fourth pack with more volume, like a 45 or a 50 litres, useful for more days trekking and, for a photographers like me, for more photography gears.

I saw this product in Germany with a friend of mine and was glad to know it was available here as well. I like to bike and run and with these two backpacks I can do both without paying extra.

Love it. It's high quality at a very reasonable cost.
