The rise in popularity of outdoor recreation has increased the demand for outdoor equipment. A specific genre of outdoor recreation is called light weight backpacking and participants in that genre creates a demand for lighter outdoor equipment with the same resistance to weather and wind as heavier equipment. The aim of this study is to improve the wind resistance of a lightweight gas stove. This thesis addresses questions about how the existing pot supports affect the wind resistance and how to improve the design. The work is practical rather than theoretical and the data collection comes from testers with the existing product and prototypes. Results from the tester with the existing product shows that the wind direction and wind speed have a great impact on the performance. One of the prototypes was chosen for further development after assessment with the help of a Pugh matrix. The chosen prototype had an average improvement of 18,3% in boiling time and 13,8% in gas usage, regardless of wind direction. The resulting CAD-model of the chosen prototype shows an added weight of 8,44 g and added height of 10 mm compared to the existing product. The additions are still within the product requirements. Since the product is a lightweight gas stove, any weight addition should be defendable. In this case the added weight is less than the weight of gas saved on three uses with the new prototype. When repeating two of the testers, the new results differ from the original ones which adds a margin of error to all testers. This is because the built-in pressure regulator had an inconsistent performance depending on the pressure in the gas container.
