Most people may think that the waterproof bag is not a must -have equipment for mountain climbing, and can be replaced with plastic bags or large garbage bags.

But plastic bags have the following 3 disadvantages:

It cannot be completely waterproof, causing a long period of rain or heavy moisture on the mountain.

There is no breathable function, causing anti -tide in the bag, and electronic products are easily damaged.

There is no compression function, and items that are easy to swell, such as sleeping bags and down jackets, will occupy many backpack spaces and reduce use efficiency.

The above disadvantages will cause many inconveniences in the process of climbing, so I think mountaineering waterproof bags are actually very important climbing equipment. This article should share how to help yourself choose a suitable hiking waterproof bag.

How to choose a mountaineering waterproof bag?

There are three main selection points for climbing waterproof bags

1. Capacity

The capacity of the waterproof bag is available from a small waterproof bag of 1L to a large waterproof bag of 90L.

<10L: Suitable for packaging (separation and spare clothing separation), personal items storage (electronic products, wallets, headlights)

10-40L: Suitable for equipment with large volume, such as: sleeping bags, down jackets

> 40L: Suitable for the second layer of waterproof layer. Put all the waterproof bags and then put them into the largest waterproof bag to avoid the first layer of waterproof bags from damage.

2. Fabric material

The waterproof bag is divided into Nylon and Event according to the cloth material. Nylon is divided into 15D, 30D, 70D according to the fibrous thickness. D is the abbreviation of Denier Daniel. It is used to express the weight of the wire wire in the length of the unit. The weight of 15g is 15D and 70g is 70D. Simply put, the larger the D represents the heavier and thicker the fabric, but the higher the relatively abrasion resistance.

Event and GOREX are both airproof waterproof fabrics and are made of EPTFE film. But Event’s breathability is better than Gore-TEX, because the protection and treatment of the EPTFE film is different.

3. Function design

According to the functional design, it can be divided into perspective windows, discounted valves, and compressed designs.

The advantage of the perspective window design is that it can be clearly seen in the bag, which is more convenient to find items.

Due to the bulky and difficult operation of the water bottle, the market has gradually been replaced by Event’s breathable waterproof bag on the market.

Compressed design waterproof bags can help us save a lot of strength when the compressed volume (such as: sleeping bag).

What are the types of mountaineering waterproof bags?

The waterproof bag is divided into the following 6 types according to the fabric material and functional design: ultra -lightweight version, lightweight wear -resistant version, EVENT breathable waterproof bag, see -through window design, evacuation valve design, compressed design, can be designed with compressed design, compressed design,

I bought the Event of the Event of the Sea TO SUMMIT and the compressed design waterproof bag, which was used to pack my warm clothing, personal supplies and sleeping bags when I climbing.

After 15 minutes of splashing water testing at home, you can see that water droplets can be seen on the waterproof bag, which has not penetrated at all.

It can be seen that the volume after compression does become much smaller, the compression process is not effortless and it is easy to operate.

The above is the choice method of sharing 6 mountaineering waterproof bags and recommendation. I think I think it is quite worthwhile to start with SeatOSUMMIT breathable waterproof bags and compressed waterproof bags.
