2. Supervision
Although the first priority for buying men's and women's backpacks is the material of the bag, but the appearance, design, and color are the first priority in buying girls' and children's backpacks, because children's connection with objects and devices is visual, and appearance is a much more important issue. is Although it is important to use bright and lively colors, because color is a matter of taste, it is better to ask your child's favorite color before buying a school backpack. Because the variety of colors and designs in school bags and backpacks is high and the customer's hands are open. In addition to color, design and printed photos are also important because every child loves a cartoon and animated character.
2. Sizes and sizes
The gender and height of the student are the criteria for buying a school bag. So avoid buying a big bag separately because nothing is more painful for kids than carrying a big and heavy bag! The wheeled luggage backpack is an ideal purchase for first graders who are short and tall due to its easy carrying and easy handling. Of course, the size of the school backpack should be proportional to the number of books and notebooks of the student. Therefore, the size of a secondary school student's backpack is definitely different from the size of a primary school student's backpack. The width of the school backpack should not be greater than the width of the student's shoulders because it puts a lot of pressure on the shoulder and causes the student's bones to deform. The length of the backpack should not be longer than the belt.
2. Genus
In addition to the variety in design and color, there are also various types of backpacks in the market. From canvas backpacks to leather backpacks, each has its own advantages and disadvantages. For example, a leather backpack is not at all suitable for a 10-15 year old student because leather is difficult to care for. On the other hand, the fabric school backpack does not need any special care and can be washed and cleaned many times. Plastic and polyester backpacks are also suitable for small children and girls due to their light weight. Most fancy girls' backpacks are also in the category of polyester backpacks because it is possible to print various designs and colors in plastic and polyester and it is durable.
Design
Although the standard two-pack backpack has a lot of sales, the single-pack backpack is also one of the products that has its own fans. Its fashionable and new design has made it experience high sales. Of course, the drawback of the crooked strap school backpack is the pressure on one shoulder and hand, which is due to its asymmetric design, because the weight of the backpack and its contents are not divided between the two straps, which makes the student tired. The wheeled backpack, which we mentioned earlier, has a suitable design, and since the load and weight of the backpack and its contents are placed on the wheels, there is no pressure on the student's body and hands. Of course, the wheeled luggage school backpack is not a good option for middle school children! And it is more suitable for children under ten years old, because this age range is small and has little physical strength, and it is difficult and annoying for them to carry a backpack.
5. Air ventilation pad
The pads used in the back of the backpack, which is in contact with the student's waist, is a valuable and practical option that is more common in large backpacks and hiking backpacks, but is also used in some school backpacks. These spongy bumps bear the pressure caused by the contents of the backpack to some extent, and this causes less pressure and weight to be applied to the student's shoulder, back and neck. Another positive point of these pads is to help air circulation where the student's waist contacts the school backpack, and this exchange of heat and air prevents the student from sweating and his clothes from getting wet. In some more expensive and newer models, air capsules are used in the backpack strap, which helps a lot in removing the pressure caused by the weight of the backpack and its contents. Finally, although this option is practical, it is not very usable and does not work in light and compact backpacks that are often designed for students.
What will reduce the life of the backpack?
1- Sharp and winning equipment: it doesn't matter whether the school backpack is cloth or leather; However, it is vulnerable to sharp objects. Therefore, as much as possible, keep the bag away from the winning equipment. Of course, sharp tools do not only include knives, and pencils or even rulers may also damage the inner lining of bags and backpacks. Therefore, it is better to put the pencil and pen in a solid and put the ruler and other tools in the large pockets of the school backpack because tight spaces cause the pressure of the edges of the ruler, which are often sharp, to be greater, which eventually causes damage. 2- Additional load: One of the important issues mentioned in the above headlines was the suitability of school backpacks. In other words, if there are a lot of books, notebooks, and other student items, it is better to order and buy a bigger backpack because one of the factors that reduce the useful life of a backpack is carrying extra weight. Detachment of the stitching from the seams, damaged zippers, torn straps, etc. are among the disadvantages of buying a small and disproportionate school backpack. 3- Dirt and pollution: To wash fabric and canvas bags and backpacks, you do not need to wash them in a washing machine because children's bags and backpacks are washed monthly and do not have deep pollution and dirt that require long washing. To do this, put the school backpack in a pan of hot water plus half a pint of washing powder and after half an hour, clean the body of the bag and backpack with a very soft brush. To wash the delicate parts of the bag, you can use a cloth dipped in washing liquid. Plastic and polyester backpacks do not need to be washed and can be cleaned with a damp cloth. Cleaning and cleaning a sports backpack for girls is more difficult than cleaning other bags because they are more elegant than other bags and backpacks, so more patience and time should be spent cleaning them.
Suitable backpack
The first thing to consider when buying a suitable school bag is the gender of the student. Because the design, printed photos and even the color of the bag should match the gender of your child. Of course, color and photo compatibility is not an important issue for elementary and primary school children, but for students over 12 years old, the issue of color and design compatibility must be observed. The next issue is the weight of the school backpack, according to a claim, the weight of an empty backpack for students should be less than one kilogram and for elementary school children, this number should be less than 500 grams because heavy weight causes defects in the body's skeleton and anatomy. The weight of a full school bag should be less than 10% of the student's weight so that the pressure and weight of the school bag does not harm the student's back, shoulders, neck and hands. Denim and linen school backpacks are heavier than other backpacks. Therefore, if you are going to buy linen or denim bags and backpacks, it is better not to carry heavy things with them because linen or denim bags are heavy enough.
Another point is the ability to wash, which we explained in the above headlines. Since elementary school children have little commitment and responsibility and they constantly dirty their school bags and backpacks, the backpack suitable for students under the age of 15 is a bag that can be easily washed. Additionally, you should choose and purchase a fabric that dries quickly.
The supporting strap and the need to use it is another important issue that is practical and efficient in backpacks that have a heavy weight. Although there is no need for a supporting strap in the backpack of elementary school students, because the weight of school supplies is not that heavy for elementary and primary school students, but for students who may have 8 hours of class during the day, the mentioned strap is practical and can be a considerable amount. Consider the weight of the school backpack.
Do not neglect the extra pockets, even if they are small! A place for a thermos or water bottle, a place for keys, a place for money or a bank teller, etc., are among the advantages of these additional pockets. Independent pockets may be zipped or open; Like net pockets on both sides of bags and school backpacks that hold water bottles and thermoses. In some backpacks, there is a separate place for the laptop inside the bag, and there are small and large protective bubbles on both sides of the said part. The task of these air-filled bubbles is to remove possible shocks caused by impact or dropping the bag on the ground so that the laptop or tablet is not damaged. This option is for students' bags and backpacks who have to carry a laptop to do university work.
