TEST: With a volume of just 1,64 L, the Bontrager Rapid Pack Hydro is the smallest hip bag in our list of the best. Nevertheless, the interior looks as if it could accommodate everything needed for normal tours. You can find out here whether this is really the case and how the hip bag performs on the trail.
Bontrager Rapid Pack Hydro in the test
Visually, the Bontrager Rapid Pack Hydro looks like a wide belt - you won't find the classic look of a hip bag here. However, this design promises a body-hugging distribution of the load, which in turn should result in a comfortable fit and no wobbling. The hip bag is made of lightweight fabric and, in addition to the included hydration bladder, also holds a bottle. Two patch pockets hold tools, cell phones, keys and similar things. Bontrager – Trek’s house brand – relies on a wide but unpadded webbing around the hips. There is no holder for protectors.
Facts & figures


Compartment layout & inner workings
The wide hydration bladder is stored in the large main compartment of the hip bag. A spare hose and a pump can also be easily stored here. The latter even has its own Velcro fastener, which is positioned in such a way that it gets in the way of any items of clothing. When the hydration bladder is completely full, accommodating a jersey becomes a little bit of darning work - on the other hand, if you use a bottle, you can accommodate two pieces of clothing despite the small pack volume.
The two patch pockets have small inner pockets made of neoprene, which are ideally designed for mobile phones, wallets, tools and bars. Everything is neatly stored here and the bag sizes are appropriate. Overall, all pockets and compartments are easily accessible.

Strap & adjustment options
When it comes to adjustability, the Bontrager Rapid Pack Hydro is simple. A wide but unpadded strap can be easily adjusted on both sides. For example, the hip bag can be loosened a little quickly and easily for uphill riding. The seat is quite comfortable and good.
A wide, integrated elastic band ensures that the contents of the bag are automatically compressed and also keeps a drinking bottle securely in place. This works quite well even without a bottle and when the pockets are not full.
In action & on the trail
If the hip bag is well filled, its shape will be somewhat round. It no longer fits the back ideally and tends to wobble in rougher sections. If the level is low, the problem is hardly noticeable. Even with the use of a bottle it hardly exists as there is simply more space inside.
The handling on the go is pleasant and unobtrusive and can therefore be described as very good. The small inside pockets in particular are good and make friends when using them.
