Development of some icons

Industry: Sports and Fitness
Design details: I am looking to develop 6 icons to represent the effect of garment design on the thermal insulation values of clothing. In other words, an icon that represents superwarm clothing, less warm and so on. These icons would be used in an app. Users will have to select which icon is the closest to the garments they are wearing. I have attached a few examples (some rough drawings and an existing example). The app is for athletes in all sorts of sports. The icons need to be about sport and cannot be regular clothing (shorts and a singlet for example but no dresses or suits).
Target audience: Athletes
Ideas for the visual style: icons stule, think black lines, simple
Preferred colors: b/w
Urls to draw inspiration from: attached examples
Where the design will be used: in an app, to indicate clothing an athlete is wearing
Extra notes: Notes to go with the attachments: The icons should be close to the icons used in the second screenshot with the text. My own drawing can be used as guidance for all 6 icons and the drawing at the top is an existing version that is used for normal clothing, not for athletes. This one is just for context.
