Which waterproof bag fabric is good? How to choose a waterproof bag? Judging from the name "waterproof bag", as the name suggests, it is a waterproof bag. But in fact, a real waterproof bag has more than a simple waterproof effect.

Just imagine, when many travel friends go out to play, they go not only to places with water like Sanya or islands, but also to go through the mountains and into the forest, and it is common to spend the night in the mountains; , The wear resistance and rub resistance of the bag are also very important.

Therefore, most of the waterproof bags on the market now use TPU material, which not only has better waterproof effect than ordinary materials, but also has excellent wear-resistant and scratch-resistant protection effects. The most obvious type of bag is a caving bag; when you go into a cave when you go into a cave, if the bag is not wear-resistant, it will break when you rub it.

The so-called waterproof fabric, generally the surface of the fabric is treated with a waterproof agent, or the surface of the fabric is coated with plastic, PU, PVC, PA, etc., so that the fabric has waterproof work clothes, waterproof jackets, waterproof travel clothes, and can be used as umbrella cloth. , tent cloth, luggage cloth, school bag cloth, hat cloth, shower curtain cloth, car cover, cargo covering cloth, etc., so its sales are increasing year by year.

How to choose a waterproof bag

Step 1: Think about the type of your itinerary

The first condition to decide on a suitable travel waterproof bag is to be able to match the type of activity to be considered.

1. The length of the itinerary;

2. The number of times used in a year;

3. The type of sports you engage in in outdoor activities;

4. What kind of area will be explored;

Step 2: Decide on the Basic Style of a Travel Waterproof Bag

Soft Bags: Small-Medium Size Waterproof Bags Without Internal Support Structure

advantage:

1. The price is cheap and convenient to buy;

2. Lightweight and does not account for volume.

shortcoming:

1. The capacity is so small that it is difficult to meet even basic sleepover activities;

2. Basic carrying system cannot comfortably carry large or heavy equipment

Outer frame type waterproof bag: The fixed outer frame type structure can evenly distribute the equipment between the shoulders and hips, and the waterproof bag body and the carrying system are attached to the outer frame.

advantage:

1. It can provide huge carrying capacity on easy to moderately difficult routes;

2. There is a large amount of storage space inside the waterproof bag body, and it has convenient compartments, side pockets, and outer pockets to facilitate packaging and access to equipment;

3. The ability of external hanging is powerful, which can effectively hang a large number of equipment on the external frame;

4. Because the back of the body and the back frame are lined with a breathable mesh belt, it has good air permeability, and it is more ventilated and dry to use;

5. Compared with the inner frame waterproof bag of the same size, the price is relatively low.

shortcoming:

1. Larger, wider and heavier in weight;

2. The center of gravity of the outer frame type waterproof bag is obviously relatively high when it is filled, and it is difficult to maintain balance in difficult terrain, especially when climbing rock walls or drilling arrows in bamboo forests;

3. The head movement space is limited;

4. The carrying system is not ergonomically designed, so it is not comfortable to carry.

Internal Rack: A structured support system inside the main body of the travel bag effectively distributes the weight evenly between the shoulders and hips.

advantage:

1. The adjustable carrying system can be adjusted according to different body types, which is convenient and comfortable to use;

2. The smooth shape with a streamlined profile has more range of motion and free stretch elasticity in difficult terrain or cramped narrow spaces;

3. The close-fitting design can move the center of gravity of the packaged load along with the center of gravity of the body, making it easier to maintain balance.

shortcoming:

1. The main compartment of the waterproof bag is limited, and it is not easy to pack;

2. Carefully and carefully pack in advance to avoid the dilemma of being unable to find the equipment temporarily or urgently;

3. Because it is attached to the back, the ventilation and ventilation are very poor, and it is often easy to sweat.

4, the price is generally high

Step 3: Decide on the waterproof bag material

Using PU coated nylon fabric (eg: PU coated 450D polyester, 210D nylon), it has the functions of waterproof, anti-dry, wear-resistant, tear-resistant and so on. Whether a waterproof bag is durable or not depends on the fabric. I don't think everyone wants to encounter the situation where the waterproof bag is broken when the donkey is halfway through.

Step 4: Decide on the size

Look for a travel waterproof bag that's big enough to hold all the necessary gear, but small enough to comfortably carry on a day-to-day basis. Remember! No matter how big a travel waterproof bag is, users usually tend to fill up the waterproof bag. Unless it is really necessary, avoid extra-large waterproof bags as much as possible. Generally, the size of the waterproof bag is classified in Europe and Asia. The size of the waterproof bag has a large capacity. The unit of calculation is the number of liters (liters) that can be accommodated:

Below 30 liters: small waterproof bag, suitable for general hiking in the suburbs;

3055 liters: multi-purpose waterproof bag, mostly used for rock climbing, river tracing, suburban mountains or weekend camping;

5580 liters: widely used large waterproof bag, used for intermediate mountain and alpine walk;

More than 80 liters: expedition-type large waterproof bag, long-term mountain walks, overseas expeditions.

Precautions:

1. The inner frame type waterproof bag usually fills the sleeping bag in the lower compartment of the main bag, but the general outer frame type waterproof bag places the sleeping bag on the outer lower layer of the back frame;

2. There are some differences in the calculation of capacity between different manufacturers;

3. The size of the waterproof bag should also consider the difference in height of each person. For example, those with a shorter stature are not suitable for carrying a super-large outer-frame waterproof bag.

Step 5: Consider the look and function of a travel waterproof bag design

Once the correct style and size are determined, the next step is to compare the individual design differences between each waterproof bag. The convenience of packaging should make the waterproof bag easy to organize, and the equipment is easy to access. When packing and unloading the waterproof bag, it is customary and convenient. The following Here are some points to note:

1. How many compartments in the main belt;

2. The way of compartment design - top cover belt type or zipper open type;

3. The number and configuration of small pockets or side pockets.

multifunctional design

Most modern waterproof bags will emphasize multi-functional design to add more equipment matching or technical performance. For example, the side groove pocket can store column-shaped equipment such as camp posts, mountain knives, trekking poles, etc., and the extension bag can increase the capacity and strengthen the waterproof bag. Waterproof (snow) function, crampons, sleeping pads, etc. can be added to the crampon belt on the top cover.

Durability

The use of waterproof bags is to pass the multiple tests of time, high torture and pressure. It is important to find a light and wear-resistant material! At the same time, attention should be paid to whether the stitching is firm, whether the zipper and opening are strengthened, whether the bottom of the waterproof bag is strengthened with double-layer treatment, and whether the contact point between the strap and the main body of the waterproof bag is strong enough.
