The Amplifi Stratos MKII offers a long list of features, ranging from back protectors and a rain cover to a tool bag. We tested what these are good for

Very comfortable - but relatively heavy

The most important thing about a bike backpack is still its comfort. And this is where the Stratos scores highly. The straps are optimally cut and ventilated, the hip belt is tight and supports the backpack well. The Armourgel insert on the back allows the rucksack to fit snugly. Another advantage: the Armourgel also serves as back armor. Although the back is ventilated by mesh inserts, the obligatory sweat line on the jersey is still unavoidable. On the trail, the Stratos sits firmly on the back, no sliding up on the downhill, no bobbing when pedaling. The first impression is convincing. The only drawback: when you lift the Stratos for the first time, you inevitably get the feeling that the rucksack is already packed. The tested version in size L weighs just under two kilograms.

Diverse features

The Stratos not only sits comfortably, it also impresses with its features: the tool bag supplied keeps the rucksack tidy and organized. Thanks to the cell phone and glasses pocket, important companions on a day trip are well protected. Thanks to the discreet fastening system, pads and full-face helmet can be easily attached. And should the rain pour through the clouds, you are well equipped thanks to the concealed rain cover. Amplifi does not include a hydration bladder. The necessary sleeve inside and the holders for the drinking tube are already included.

Conclusion

Even after our extended test, the Stratos looks like new. Sweat and dirt were unable to damage the backpack. The Stratos is extremely spacious (23 liter capacity in size L), but sits well on the back even with smaller pack units. The Stratos is extremely comfortable to wear, and sits quietly and securely. The only drawback is the relatively high weight - but thanks to the back protector, this can be overlooked.
