Features to Consider Before Buying
Quality backpacks are manufactured from polyamide and polyester materials. They come in various shapes and sizes, but usually a backpack, which includes an internal frappe backpack, is intended for long hikes.
Most internal frame models are highly organized with numerous compartments. Moving through nature could lead you to different situations and every piece of equipment, which is not essential, should stay home. A backpack, which is not well organized, could also be a potential problem.
It will fall off, get damaged, limit the mobility of a person and even lead to injuries. If you are space limited when packing your gear, then the general rule is the pack upwards, which means adding equipment above the backpack. The hiking poles should be packed faced down and all the gear with sharp edges should be isolated.
Tie Up Straps
The tie up of the straps should be done in a way to help in the weight distribution. The straps should always hold the backpack straight. The gravitational center of the backpack should always be around the hip area.
Othervise, you might end up losing your balance all the time and that can be dangerous, especially if you are in mountain areas.
Most backpacks have an additional layer, which is completely waterproof. However, there are not many backpack manufacturers that are waterproofing the zipper sections. We can protect the backpack from the rain or other humid conditions by adding an additional cover.
Some of the backpacks presented below have a built in cover at the bottom of the backpack.
Size and Capacity
The size you can choose depending on the length of your trips:
- 15-40 L are intended for one day hiking trips
- 40-60 L are for several days hiking
- 60 -100 L are for long backpacking trips
For a several days backpacking trip, it is best that you combine two sizes of backpacks; a small one for daily trips and a large one, which would stay at the campsite location.
When choosing larger backpacks, focus on the waist straps because the hips carry 60% of the weight. Of course, the choices and preferences of an individual should also be taken into consideration. Still, the practicality of a backpack is very important.
Choose a backpack, which would be able to carry all your essential gear. Make sure it has more internal pockets. When choosing a heavy category backpack it is vital that we try it on fully packed in order to check how it handles the weight.
