Your weight is only of marginal interest to us. What is important is what kind of clothing you are going to be wearing. In most cases today, we recommend life jackets with 275 Newton. We do this for the following reasons:
As a rule, a life jacket has a life time of 10 to 15 years. However, you do not know today which items of clothing you will have acquired in the next few years or into which cold waters you will dare to venture into in the next 8 years. But since the weight of a 275N life jacket is not substantially greater than that of a 150N life jacket, and the price difference is likewise insignificant, even today we are recommending tomorrow's standard.
