The Naturehike backpack bag is positioned as a unisex solution for outdoor activities.

The model is available for sale in various colors, and the main tones (blue, black, gray) complement the bright inserts (light green, blue, orange, etc.), which not only act as a design feature, but also increase the visibility of the product in the dark .

One of the main features of the Naturehike 6L Chest Bag is its light weight(only 155 grams). The backpack is made of medium-density nylon fabric (320D), which is claimed to have good waterproof properties. But due to the thinness of the materials, you should not expect that the contents will remain dry during severe precipitation.

The capacity of the backpack is 6 liters, which is generally small, but typical for single strap models. The main compartment will fit a tablet up to 10 inches, a T-shirt or a thin jacket, a light snack. A front pocket is offered for documents or small items. The keys are conveniently hidden in a small compartment with a zipper on the shoulder strap. In addition, there is an elastic pocket for a water bottle on the side.

You can wear the model both on your back (throwing it over your shoulder or just on one shoulder), and moving it on your stomach. The only strap is easily adjustable in length, also thanks to high-quality YKK fittings. And the disadvantages include the lack of ventilation of the back, because of which intense sweating is not excluded in the heat.

But given the low cost, Naturehike 6L Chest Bag looks like a good budget solution for short bike rides, weekend trips or various city trips.

Price, the possibility of hanging the strap, 3 pockets in the main compartment.
Modest capacity.

In the Xiaomi branded line, the shoulder sling bag can be considered the little brother of the Minimalist Urban Style urban backpack. Both models received similar zippers and are made from the same polyester fabric. The latter is characterized by a pleasant appearance and tactile sensations, keeps its shape well, and is also able to “get out of the water dry” with slight precipitation (due to water-repellent impregnation).

The main differences are related to the number of straps (Xiaomi Multi-functional Urban Leisure Chest Pack has one) and dimensions (32x17.5x8 cm versus 30x39x14 cm).

The single strap backpack has a mesh back designed to improve ventilation properties. And the only strap here is fixed both on the right and on the left, which will allow you to throw the model over any shoulder or periodically change sides.

In total, Xiaomi Multi-functional Urban Leisure Chest Pack has two compartments: main + bottom pocketdesigned for various small things. In the main compartment, it is not difficult to correctly distribute the necessary things, avoiding disorder. All thanks to the three inner pockets: two open (for a laptop and a small tablet) and one small with a zipper.

The backpack visually looks larger than it actually is, and its capacity is modest even by the standards of single-strap counterparts - only 4 liters. And it is unlikely that it will be possible to exceed this value, since the dense fabric almost does not stretch. So, only A5 documents, a wallet, a phone, a tablet up to 8 inches will fit inside (larger models need to be tried on), various small accessories, such as a Power bank battery or an action camera. Or instead of gadgets, you can take two half-liter bottles of water.

If you don’t take it for a walk or work anymore, then the Xiaomi Multi-functional Urban Leisure Chest Pack is an excellent backpack, which is also very affordable.
