Answer:
The jacket is thin because it uses a fiber called thinsulate that enables it to have the lightest weight but is also the warmest.
Step-by-step explanation:
In general marketing, the boomerang method refers to the 'reconstruction' of the customer's objection into the main reason for buying. In other words, using the same excuse that a customer has about a product to entice him/her to buy that product by reframing it as a selling point is known as the boomerang method.
In the given scenario, the customer's objection is about the thinness of the jacket can be used as a selling point by the salesman by stating that the lightness of the jacket is what makes it a good product. So, if the seller tells the customer "the jacket is thin because it uses a fiber called Thinsulate that makes it thin but also warm", then that will make it an interesting and important factor for the customer to like the product more.
