The surface of the water droplets can form a bead-like diffusion without penetrating and wetting the contents of the bag to achieve a water repellent function like a lotus leaf.

(a) The first practical lesson

In order to match the Kaile stone backpack, I chose a brand of kaile stone clothing. Look at what's in your backpack today. SLR cameras, mats, hammocks, jackets, glasses, gloves, small speakers, trekking poles, paper towels, water, snacks and other miscellaneous items. The total weight is 7.1KG.

My height is 170cm. After the bag is packed, we arrange all the drawstrings to receive the bag body. Should adjust the shoulder straps, chest straps, belts, etc., respectively, so that the backpack's weight evenly distributed to the entire back.

Place the kettle into the deeper pocket, and there is a contraction band reinforcement, the kettle should not fall.

The trekking poles are not free to fall off.

Like a shoe, it doesn't fit your own feet and it's the same with a backpack. My backpack is also quite a few, ranging from small backpacks that can be accommodated at work, to large backpacks that are reloaded on foot. The backpack has a reasonable degree of force on the lumbosacral region, and the overall fit of the back, the individual feels more comfortable. The backpack's 3D carrying and multi-belt adjustment system is designed to give the shoulders enough space to relieve pressure on the shoulders. The backpack has a moderate waistband that fits over the pelvis and does not rest against the ribs. The bottom of the backpack is flush with the lower edge of the waist, the backpack load is evenly distributed, and the center of gravity is stable.

It is easy to climb and trekking. It is not because of the large-scale movement in the course of the game that it causes the backpack to shake obviously and cause discomfort to the body. Even if there are sharp rocks, messy branches when climbing, do not worry that the backpack will be worn by rocks, branches, etc.

The main red color of the backpack is matched with the green color, and the hardness and softness are combined. The color is bright and vivid, and it is very eye-catching in outdoor activities.

With temperatures around zero in winter and a few heavy snowfalls, the winds between the mountains are large and very cold. After the snow melted, it was frozen and the ground was slippery. Even the occasional ones were caught with ice. They also saw many slipping along the way. Therefore, during the march, be extra cautious and not sweat like the summer, but there will still be sweaty hair after super sports. After the back is slightly hot and sweating, this backpack will speed up perspiration and perspiration, not only will not feel stuffy, nor will it be cold and lose temperature due to sweating and more strokes. Carrying a bag on the back is like wearing a thick vest and resisting the attack of strong winds on the back, which functions to keep warm. It can be said that this backpack combines breathability and warmth.

(b) The second practical lesson

Look at what's in your backpack today. Tents, sleeping bags, mats, egg nest mats, trekking poles, barbecue grills, carbon, food, water and more. Total weight 12KG.

The above items should be properly put into the backpack. What is particularly noteworthy here is that in order to assist the outer tent on the top bag, another two additional straps are found, bound by the four outer rings of the top bag.

In this way, you can free your hands when walking. Moreover, the weight of the backpack is evenly distributed and balanced.

After a few kilometers on foot, I found a good waterside and camped here.

Keep your backpack on the floor without worrying about getting wet or dirty.

The smell of smoke in the barbecue process is very large, and often the smell of smoke is smoked. The fabric of this backpack is not easy to absorb smoke. Even in the process of grilling, accidentally using a stained, charcoal hand to get the backpack, it is not easy to soil.

Summary advantages:

1, lightweight backpack, suitable for hiking, hiking, travel and many other activities.

2, 3D piggyback system, multi-band adjustment system, so that the backpack load evenly distributed, carrying comfortable.

3, multi-pocket, multi-point plug-in, independent sleeping bag warehouse, water bag warehouse and other design, so that the object storage more convenient.

4, unique watermelon red and green collocation, hardness and softness, is my favorite.

Suggest:

1. It is recommended that chest strap buckles be added to emergency whistle, and reflective strips be added outside the backpack to improve safety.

2, it is recommended to add rain cover. One is to prevent heavy rain, and the other is to better prevent scraping and soiling of backpacks.

3. It is recommended to add a few spare straps to facilitate external use.

4, I got the backpack, the right side of the contraction band, may be in the sewing installation of tape, more twisted in a circle, leading to shrinkage band is not smooth, does not affect the general use. However, if the moisture-proof pad and other items are externally attached, there will be a case of a cassette with a more-twisted shrink tape. It is recommended to check the bag's straps, buckles and other details at the factory.
