Amplifi Hipster 4 review
The hip bag is developed in the tranquil Allgäu in Oberstdorf. When it comes to production, Amplifi uses recycled and certified materials whenever possible. The Waistbag is designed for the use of a hydration bladder - but is delivered without it. Of course, this can be purchased as an option. The Amplifi Hipster4 comes with a practical interior and an easy-to-adjust hip belt. Larger side pockets on the fins offer good accessibility. Overall, the hip bag looks very promising at first glance. Practical details such as a mounting option for the rear light and an easy-to-grip zip round off the positive appearance.

Compartment layout & inner workings
The layout of the Hipster4 is mostly convincing: the main compartment can be opened wide, allowing for easy packing and inserting the hydration bladder. Things like a pump, hose and wind jacket can also be stored in this compartment. Also included is a small strap with clip for your key. However, this then dangles loosely in the compartment. The front pocket for utensils is also practical: it can be opened at the top with a zip, or opened completely with a second zip and Velcro. The compartment division works well for multi-tools, CO² cartridges, bars and the like. In the middle you have to decide a bit between smartphone and wallet. The accessibility of the subjects is good.
The disadvantage is that the hydration bladder with its wide shape does not fit optimally - the bladder is too wide for the space in the fins. Therefore, accommodating the bladder in the hip pocket is a bit fiddly. The fins themselves each have a larger pocket with a zip – there is also space for a large multi-tool or two bars.
Strap & adjustment options
The hip belt can be adjusted very easily. Tighter or looser – both are no problem and can be carried out symmetrically on both sides. The strap is attached in such a way that it automatically compresses the contents of the hip bag. The two-sided outlet for the included drinking bladder is also practical. The tube can be worn on the left or right, depending on the driver's preferences.
In action & on the trail
When the Amplifi Hipster4 is full to the brim - which is quickly the case with a pack volume of four liters - it becomes quite round. On the trail, this means that the hip bag wobbles up and down a bit in rough terrain. Otherwise, it fits well and comfortably for the most part, but could fit better overall. If it is not so full, the problems hardly show up. The adjustment of the straps and the handling in general are convincing for the most part. The only thing we missed was a holder for the protectors. In the event of a breakdown, the fully hinged front compartment is very practical.
