The equipment of the climbers in the movie is not luxurious, but very basic, but it will certainly meet the basic needs. It may be because the more luxurious the equipment, the greater the weight. It is said that such equipment already has 17 kg. You can imagine how difficult it is for actors.

The greater the load, the greater the risk factor, and even experienced ice climbers will not wear a lot of equipment. Therefore, after seeing the actors' equipment, many netizens are still very worried, saying that it is good to perform safely in such an environment. I have seen videos of talented people doing extreme sports before, not to mention inexperienced people.
