This project investigates the merging of performance apparel from mountain biking and ski touring, based on the emerging trend in combining mountain biking and ski touring as sports. Designing apparel for a combination of sports could contribute to a sustainable change in the outdoor industry by affecting the design thinking, demand and consumerism. All the garments are developed based on the female body and needs. This is shown through both commercial pieces and experimental pieces, with garment shapes that are both similar and not so similar to existing garments. Material placement is based on movement and thermoregulatory responses of the female athlete and plays an important part to achieve both expression and function in the garments. The methodology is explained through five parts; field testing, sketching, prototyping, experimenting and evaluation, which are used both numerical and independently of each other. This resulted in a collection of seven outfits where three of these are produced and the remaining four are illustrated through development, sketches and technical descriptions. Results show suggestions of how a combination between sports could be developed and used. It also shows potential to be developed even further into other various directions.
